Modern technologies in the field of detection and development of fires are developing very rapidly today. The latest developments can surprise not only with their appearance; for example, robotic technology is now used in the field of extinguishing and eliminating the consequences of natural disasters.

In our article we will tell you about another fundamentally new technology that is being actively introduced and used in the modern world.

Methodological plan summary by the DOWNLOAD button

Unmanned aircraft can be widely used to solve special problems when the use of manned aircraft is impossible or economically unprofitable:

  • inspection of hard-to-reach areas of the border,
  • observation of various areas of land and water surface,
  • determining the consequences of natural disasters and disasters,
  • identifying outbreaks, performing search and other work.

The use of UAVs makes it possible to monitor the situation remotely, without human intervention and without exposing him to danger, over fairly large areas in hard-to-reach areas at a relative low cost.

Types

According to the principle of flight, all UAVs can be divided into 5 groups (the first 4 groups are aerodynamic type vehicles):

  • with a rigid wing (aircraft-type UAV);
  • with flexible wing;
  • with a rotating wing (helicopter-type UAV);
  • with a flapping wing;
  • aerostatic.

In addition to the UAVs of the five groups listed, there are also various hybrid subclasses of devices, which, based on their flight principle, are difficult to unambiguously attribute to any of the listed groups. There are especially many such UAVs that combine the qualities of aircraft and helicopter types.

With rigid wing (airplane type)

This type of vehicle is also known as a rigid-wing UAV. The lift of these devices is created aerodynamically due to the pressure of air flowing onto the fixed wing. Devices of this type, as a rule, are characterized by a long flight duration, high maximum flight altitude and high speed.

There are a wide variety of subtypes of aircraft-type UAVs, differing in the shape of the wing and fuselage. Almost all aircraft layouts and types of fuselages that are found in manned aircraft are also applicable in unmanned aircraft.

With flexible wing

These are cheap and economical aerodynamic aircraft, in which not a rigid, but a flexible (soft) structure made of fabric, an elastic polymer material or an elastic composite material with the property of reversible deformation is used as a load-bearing wing. This class of UAVs includes unmanned motorized paragliders, hang gliders and UAVs with elastically deformable wings.

An unmanned motorized paraglider is a device based on a controlled wing parachute, equipped with a motorized cart with a propeller for autonomous take-off and independent flight. The wing usually has the shape of a rectangle or ellipse. The wing can be soft, have a rigid or inflatable frame. The disadvantage of unmanned motorized paragliders is the difficulty of controlling them, since the navigation sensors are not tightly connected to the wing. Their use is also limited by the obvious dependence on weather conditions.

Rotating wing (helicopter type)

This type of vehicle is also known as a rotating wing UAV. They are often also called vertical take-off and landing UAVs. The latter is not entirely correct, since in the general case, UAVs with a stationary UAV can also have vertical takeoff and landing.

The lift force of this type of aircraft is also created aerodynamically, but not due to the wings, but due to the rotating blades of the main rotor (rotors). Wings are either absent altogether or play a supporting role. The obvious advantages of helicopter-type UAVs are the ability to hover at a point and high maneuverability, which is why they are often used as aerial robots.

With a flapping wing

UAVs with flapping wings are based on the bionic principle - copying the movements created in flight by flying living objects - birds and insects. Although there are no mass-produced devices in this class of UAVs and they do not yet have practical applications, intensive research is being carried out in this area all over the world. In recent years, a large number of different interesting concepts of small UAVs with flapping wings have appeared.

The main advantages that birds and flying insects have over existing types of aircraft are their energy efficiency and maneuverability. Devices based on imitation of the movements of birds are called ornithopters, and devices that copy the movements of flying insects are called entomopters.

Aerostatic

Aerostatic-type UAVs are a special class of UAVs in which the lifting force is created primarily by the Archimedean force acting on a cylinder filled with a light gas (usually helium). This class is represented mainly by unmanned airships.

An airship is a lighter-than-air aircraft, which is a combination of a balloon with a propulsion device (usually a propeller (propeller, impeller) with an electric motor or internal combustion engine) and an attitude control system. By design, airships are divided into three main types: soft, semi-rigid and rigid. In soft and semi-rigid airships, the shell for the carrier gas is soft, which acquires the required shape only after the carrier gas is pumped into it under a certain pressure.

In soft-type airships, the invariability of the external shape is achieved by the excess pressure of the carrier gas, constantly maintained by balloons - soft containers located inside the shell into which air is pumped. Ballonets, in addition, serve to regulate the lift force and control the pitch angle (differentiated pumping/injection of air into the ballonets leads to a change in the center of gravity of the device).

Semi-rigid airships are distinguished by the presence of a rigid (in most cases along the entire length of the shell) truss in the lower part of the shell. In rigid airships, the invariability of the external shape is ensured by a rigid frame covered with fabric, and the gas is located inside the rigid frame in cylinders made of gas-tight material. Unmanned rigid airships are practically not used yet.

Classification

Some classes of foreign classification are not available in the Russian Federation, light UAVs in Russia have a significantly longer range, etc. According to the Russian classification, which is currently focused primarily only on the military purpose of the devices.

UAVs can be systematized as follows:

  1. Short-range micro- and mini-UAVs – take-off weight up to 5 kg, range up to 25-40 km;
  2. Light short-range UAVs - take-off weight 5-50 kg, range 10-70 km;
  3. Light medium-range UAVs - take-off weight 50-100 kg, range 70-150 (250) km;
  4. Medium UAVs – take-off weight 100-300 kg, range 150-1000 km;
  5. Medium-heavy UAVs - take-off weight 300-500 kg, range 70-300 km;
  6. Heavy medium-range UAVs - take-off weight more than 500 kg, range 70-300 km;
  7. Heavy UAVs with long flight duration - take-off weight of more than 1500 kg, range of about 1500 km;
  8. Unmanned combat aircraft - take-off weight of more than 500 kg, range of about 1,500 km.

Granad VA-1000

ZALA 421-16E

For technical equipment of the Russian Ministry of Emergency Situations with unmanned aerial vehicles, Russian enterprises have developed several options; let’s consider some of them:

This is a long-range unmanned aircraft (Fig. 1.) with an automatic control system (autopilot), a navigation system with inertial correction (GPS/GLONASS), a built-in digital telemetry system, navigation lights, a built-in three-axis magnetometer, a module for holding and active target tracking (“ AC module"), a digital built-in camera, a digital broadband video transmitter of C-OFDM modulation, a radio modem with a satellite navigation system (SNS) receiver "Diagonal AIR" with the ability to work without a SNS signal (radio range finder), a self-diagnosis system, a humidity sensor, a temperature sensor, a sensor current, a propulsion system temperature sensor, a parachute release, an air shock absorber to protect the target load during landing and a search transmitter.

This complex is designed for aerial surveillance at any time of the day at a distance of up to 50 km with real-time video transmission. The unmanned aircraft successfully solves the problems of ensuring the security and control of strategically important objects, allows you to determine the coordinates of the target and quickly make decisions to adjust the actions of ground services. Thanks to the built-in “AS Module”, the UAV automatically monitors static and moving objects. In the absence of a SNS signal, the UAV will autonomously continue to perform the task.

Rice. 1. UAV ZALA 421-16E

ZALA 421-08M

Designed according to the “flying wing” design, this is a tactical-range unmanned aircraft with an autopilot and has a similar set of functions and modules as the ZALA 421-16E. This complex is designed for operational reconnaissance of terrain at a distance of up to 15 km with real-time video transmission. The ZALA 421-08M UAV is distinguished by its ultra-reliability, ease of operation, low acoustic and visual signature and best-in-class target loads.

This aircraft does not require a specially prepared take-off and landing site due to the fact that the take-off is carried out using an elastic catapult, and carries out aerial reconnaissance under various weather conditions at any time of the day.

Transportation of the complex with the ZALA 421-08M UAV to the place of operation can be carried out by one person. The lightness of the device allows (with appropriate preparation) to be launched “by hand”, without using a catapult, which makes it indispensable when solving problems. The built-in “Module AC” allows an unmanned aircraft to automatically monitor static and moving objects, both on land and on water.

ZALA 421-22

This is an unmanned helicopter with eight main rotors, medium range, with a built-in autopilot system (Fig. 3). The design of the device is foldable and made of composite materials, which makes it easy to deliver the complex to the place of operation by any vehicle.

This device does not require a specially prepared take-off and landing site due to its vertically automatic launch and landing, which makes it indispensable when conducting aerial reconnaissance in hard-to-reach areas.

It is successfully used to perform operations at any time of the day: to search and detect objects, to ensure the security of perimeters within a radius of up to 5 km. Thanks to the built-in “AC Module”, the device automatically monitors static and moving objects.

Advantages

The following can be distinguished:

  • carry out flights under various weather conditions, complex interference (gust of wind, upward or downward air flow, UAV getting into an air pocket, in medium and heavy fog, heavy rain);
  • conduct aerial monitoring in hard-to-reach and remote areas;
  • are a safe source of reliable information, a reliable examination of the object or suspected territory from which the threat comes;
  • allow you to prevent emergencies with regular monitoring;
  • detect (forest fires, ) in the early stages;
  • eliminate the risk to human life and health.

The unmanned aerial vehicle is designed to solve the following tasks:

  • unmanned remote monitoring of forests to detect forest fires;
  • monitoring and transmission of data on radioactive and chemical contamination of terrain and airspace in a given area;
  • engineering reconnaissance of flood areas and other natural disasters;
  • detection and monitoring of ice jams and river floods;
  • monitoring the condition of transport highways, oil and gas pipelines, power lines and other objects;
  • environmental monitoring of water areas and coastlines;
  • determination of the exact coordinates of emergency areas and affected facilities.

Monitoring is carried out day and night, in favorable and limited weather conditions. Along with this, the unmanned aerial vehicle provides a search for technical equipment that has suffered an accident (catastrophe) and missing groups of people. The search is carried out according to a pre-entered flight mission or according to a flight route quickly changed by the operator. It is equipped with guidance systems, on-board radar systems, sensors and video cameras.

During flight, as a rule, control of an unmanned aerial vehicle is automatically carried out through an on-board navigation and control complex, which includes:

  • satellite navigation receiver, providing navigation information reception from GLONASS and GPS systems;
  • a system of inertial sensors that provides determination of the orientation and movement parameters of an unmanned aerial vehicle;
  • a sensor system that provides altitude and airspeed measurements;
  • various types of antennas.

The on-board communication system operates in the permitted radio frequency range and provides data transmission from board to ground and from ground to board.

Problems to be solved

Can be classified into four main groups:

  • emergency detection;
  • participation in emergency response;
  • search and rescue of victims;
  • disaster damage assessment.

In such tasks, the senior operator must optimally select the route, speed and altitude of the UAV flight in order to cover the observation area in the minimum time or number of flights, taking into account the viewing sectors of television and thermal imaging cameras.

In this case, it is necessary to exclude double or multiple flights of the same places in order to save material and human resources.

1.2.4. Classification of UAVs by purpose

In many classifications, UAVs are divided into military and civilian by purpose. However, apparently, a more logical division is in which UAVs are first divided into larger areas of use, namely for scientific purposes and for applied purposes; the latter are divided into UAVs for military and civilian use (Fig. 1.79).

In the scientific field, UAVs are used to obtain new knowledge, and it does not matter what area this knowledge comes from and where it will later be applied. This could be testing new technology (including new flight principles) or observing natural phenomena.

Rice. 1.79. Enlarged view of UAV applications

The applied area of ​​UAV use consists of two main directions - military and civil.

Military UAVs can be classified according to their functional purpose as follows:

– observational (can be used, in particular, to adjust fire on the battlefield);

– reconnaissance;

– strike (for attacks on ground targets using missile weapons;

– reconnaissance and strike;

– bomber;

– fighter (to destroy air targets);

– radio broadcasting;

– UAV electronic warfare (for electronic warfare purposes);

– transport;

– UAV targets;

– UAV target simulators;

– multi-purpose UAVs.

The civilian area of ​​application of UAVs is very extensive. The industries and consumers of UAV services also range from agriculture and construction to the oil and gas and security sectors, as well as scientific organizations, advertising companies, the media and individual citizens. To systematize the review of the entire variety of purposes of civil UAVs, we will conditionally identify 5 enlarged groups, formed according to the criterion of the functions performed (the groups are listed in descending order of frequency of use today).

1. Monitoring and similar tasks.

This includes all tasks related to monitoring various objects, collecting measurement and other information. We list the known applications from this group:

– video surveillance for the purpose of protecting various objects;

– monitoring of forest areas by the forest protection service;

– patrolling of designated areas by the police;

– traffic monitoring on railways and highways, navigation control;

– monitoring the crops of farmers and agricultural enterprises;

– control of fisheries;

– mapping of the earth's surface;

– reconnaissance and drawing up plans of premises using small UAVs inside destroyed or dangerous buildings;

– search for minerals using special sensing tools;

– monitoring of oil and gas facilities, especially pipelines;

– inspection of construction sites;

– video photography of hard-to-reach industrial facilities (power lines, bridge supports, chimneys, wind generators, antennas, etc.);

– radiation and chemical reconnaissance in hazardous areas;

– meteorological observations;

– environmental monitoring of the atmosphere and surface of water bodies;

– monitoring of dangerous natural phenomena (floods, volcanic eruptions, avalanche-prone mountainous areas, etc.);

– assessment of the results of natural disasters and the elimination of their consequences;

– observation of wild animals in nature reserves.

This group of UAV applications is currently expanding rapidly thanks to the activities of numerous companies and individual enthusiasts. This may include the following:

– video and photography of objects of architecture, nature, business, as well as public events for the purpose of presentation or advertising;

– use of UAVs as advertising media (for example, on the surface of an airship);

– the use of small UAVs for educational purposes in schools and universities;

– aircraft modeling and aircraft design for numerous amateurs;

– the use of small UAVs as an art object or entertainment object.

3. Cargo delivery and similar tasks.

The specificity of this group of applications allows UAVs used in this way to be called aerial robots. This, in particular, can include such UAV applications as:

- mail delivery;

– delivery of tools, components and materials to construction sites;

– installation of various structures;

– performing or providing repair work on hard-to-reach objects;

– spraying chemicals and applying fertilizers on fields;

– laying cables in hazardous areas;

– delivery of products, fuel, spare parts, power supplies, etc. to hard-to-reach areas to provide for climbers, tourists, expeditions;

– resetting markers (light, radio-emitting) to indicate any objects;

– delivery of medicines and medical equipment for victims in accident and disaster zones;

– evacuation of victims from the disaster zone;

– evacuation of expensive material assets from hazardous areas;

– delivery of life-saving equipment to those in distress on the water;

– dropping explosive devices in the mountains to organize preventive avalanches;

– refueling or recharging of autonomously operating hard-to-reach devices (buoys, beacons, weather stations, relay stations, etc.).

4. Signal relay and similar tasks.

These include the following applications (usually implemented using helicopter or aerostatic UAVs):

– relaying radio signals to increase the range of communication channels;

– use of UAVs as carriers of lighting equipment;

– installation of loudspeakers on board to reproduce sound: commands, music, etc.;

– using a UAV as a platform for generating or reflecting a laser beam.

5. Control of the behavior of living objects.

These still few and rather exotic applications boil down to the following:

– using a UAV as a “shepherd”: controlling the movement of herds of horses, flocks of sheep, etc.;

– scaring away flocks of birds from airfields.

    Conducting work on the development of unmanned aerial vehicles (UAVs) is considered one of the most promising courses in the development of current combat aviation. The use of drones or drones has already led to important changes in the tactics and strategy of military conflicts. Moreover, it is believed that in the very near future their importance will increase significantly. Some military experts believe that the positive shift in the development of drones is the most important achievement in the aircraft industry of the last decade.

    However, drones are used not only for military purposes. Today they are actively involved in the “national economy”. With their help, aerial photography, patrolling, geodetic surveys, monitoring of a wide variety of objects are carried out, and some even deliver purchases home. However, the most promising new drone developments today are for military purposes.

    Many problems are solved with the help of UAVs. Mainly, this is intelligence activity. Most modern drones were created specifically for this purpose. In recent years, more and more attack unmanned vehicles have appeared. Kamikaze drones can be identified as a separate category. UAVs can conduct electronic warfare, they can be radio signal repeaters, artillery spotters, and aerial targets.

    For the first time, attempts to create aircraft that were not controlled by humans were made immediately with the advent of the first airplanes. However, their practical implementation occurred only in the 70s of the last century. After which a real “drone boom” began. Remotely controlled aircraft have not been realized for quite some time, but today they are produced in abundance.

    As often happens, American companies occupy a leading position in the creation of drones. And this is not surprising, because funding from the American budget for the creation of drones was simply astronomical by our standards. So, during the 90s, three billion dollars were spent on similar projects, while in 2003 alone they spent more than one billion.

    Nowadays, work is underway to create the latest drones with longer flight duration. The devices themselves must be heavier and solve problems in difficult environments. Drones are being developed designed to combat ballistic missiles, unmanned fighters, and microdrones capable of operating in large groups (swarms).

    Work on the development of drones is underway in many countries around the world. More than one thousand companies are involved in this industry, but the most promising developments go straight to the military.

    Drones: advantages and disadvantages

    The advantages of unmanned aerial vehicles are:

    • A significant reduction in size compared to conventional aircraft, leading to a reduction in cost and an increase in their survivability;
    • The potential to create small UAVs that could perform a wide variety of tasks in combat areas;
    • The ability to conduct reconnaissance and transmit information in real time;
    • There are no restrictions on use in extremely difficult combat situations associated with the risk of their loss. During critical operations, multiple drones can easily be sacrificed;
    • Reduction (by more than one order of magnitude) of flight operations in peacetime, which would be required by traditional aircraft, preparing the flight crew;
    • Availability of high combat readiness and mobility;
    • Potential for the creation of small, uncomplicated mobile drone systems for non-aviation forces.

    The disadvantages of UAVs include:

    • Insufficient flexibility of use compared to traditional aircraft;
    • Difficulties in resolving issues with communication, landing, and rescue of vehicles;
    • In terms of reliability, drones are still inferior to conventional aircraft;
    • Limiting drone flights during peacetime.

    A little history of unmanned aerial vehicles (UAVs)

    The first remote-controlled aircraft was the Fairy Queen, built in 1933 in Great Britain. It was a target aircraft for fighter aircraft and anti-aircraft guns.

    And the first production drone to participate in a real war was the V-1 rocket. This German “miracle weapon” bombarded Great Britain. In total, up to 25,000 units of such equipment were produced. The V-1 had a pulse jet engine and an autopilot with route data.

    After the war, they worked on unmanned reconnaissance systems in the USSR and the USA. Soviet drones were spy planes. With their help, aerial photography, electronic reconnaissance, and relay were carried out.

    Israel has done a lot to develop drones. Since 1978 they have had their first drone, the IAI Scout. During the 1982 Lebanon War, the Israeli army, using drones, completely destroyed the Syrian air defense system. As a result, Syria lost almost 20 air defense batteries and almost 90 aircraft. This affected the attitude of military science towards UAVs.

    The Americans used UAVs in Desert Storm and the Yugoslav campaign. In the 90s, they became leaders in the development of drones. So, since 2012, they had almost 8 thousand UAVs of a wide variety of modifications. These were mainly small army reconnaissance drones, but there were also attack UAVs.

    The first of them, in 2002, eliminated one of the heads of al-Qaeda with a missile strike on a car. Since then, the use of UAVs to eliminate enemy military forces or its units has become commonplace.

    Types of drones

    Currently, there are a lot of drones that differ in size, appearance, flight range, and functionality. UAVs differ in their control methods and their autonomy.

    They can be:

    • Uncontrollable;
    • Remote controlled;
    • Automatic.

    According to their sizes, drones are:

    • Microdrones (up to 10 kg);
    • Minidrones (up to 50 kg);
    • Mididrons (up to 1 ton);
    • Heavy drones (weighing more than a ton).

    Microdrones can stay in the air for up to one hour, minidrones - from three to five hours, and middrones - up to fifteen hours. Heavy drones can stay in the air for more than twenty-four hours while making intercontinental flights.

    Review of foreign unmanned aerial vehicles

    The main trend in the development of modern drones is to reduce their size. One such example would be one of the Norwegian drones from Prox Dynamics. The helicopter drone has a length of 100 mm and a weight of 120 g, a range of up to one km, and a flight duration of up to 25 minutes. It has three video cameras.

    These drones began to be produced commercially in 2012. Thus, the British military purchased 160 sets of PD-100 Black Hornet worth $31 million to conduct special operations in Afghanistan.

    Microdrones are also being developed in the United States. They are working on a special program, Soldier Borne Sensors, aimed at developing and deploying reconnaissance drones with the potential to extract information for platoons or companies. There is information about plans by the American army leadership to provide individual drones to all soldiers.

    Today, the RQ-11 Raven is considered the heaviest drone in the US Army. It has a mass of 1.7 kg, a wingspan of 1.5 m and a flight of up to 5 km. With an electric motor, the drone reaches speeds of up to 95 km/h and stays in flight for up to one hour.

    It has a digital video camera with night vision. The launch is done manually, and no special platform is needed for landing. The devices can fly along specified routes in automatic mode, GPS signals can serve as landmarks for them, or they can be controlled by operators. These drones are in service with more than a dozen countries.

    The US Army's heavy UAV is the RQ-7 Shadow, which conducts reconnaissance at the brigade level. It went into serial production in 2004 and has a two-fin tail with a pusher propeller and several modifications. These drones are equipped with conventional or infrared video cameras, radars, target illumination, laser rangefinders, and multispectral cameras. Guided five-kilogram bombs are suspended from the devices.

    The RQ-5 Hunter is a mid-size half-ton drone developed jointly by the US and Israel. Its arsenal includes a television camera, a third-generation thermal imager, a laser rangefinder and other equipment. It is launched from a special platform using a rocket accelerator. Its flight zone is within a range of up to 270 km, within 12 hours. Some modifications of Hunters have pendants for small bombs.

    The MQ-1 Predator is the most famous American UAV. This is a “reincarnation” of a reconnaissance drone into an attack drone, which has several modifications. The Predator conducts reconnaissance and carries out precision ground strikes. It has a maximum take-off weight of more than a ton, a radar station, several video cameras (including an IR system), other equipment and several modifications.

    In 2001, a high-precision laser-guided Hellfire-C missile was created for it, which was used in Afghanistan the following year. The complex has four drones, a control station and a satellite communications terminal, and it costs more than four million dollars. The most advanced modification is the MQ-1C Gray Eagle with a larger wingspan and a more advanced engine.

    The MQ-9 Reaper is the next American attack UAV, which has several modifications and has been known since 2007. It has a longer flight duration, controlled aerial bombs, and more advanced radio electronics. The MQ-9 Reaper performed admirably in the Iraq and Afghanistan campaigns. Its advantage over the F-16 is its lower purchase and operating price, longer flight duration without risk to the life of the pilot.

    1998 - the first flight of the American strategic unmanned reconnaissance aircraft RQ-4 Global Hawk. Currently, this is the largest UAV with a take-off weight of more than 14 tons, with a payload of 1.3 tons. It can stay in the airspace for 36 hours, while covering 22 thousand km. It is assumed that these drones will replace U-2S reconnaissance aircraft.

    Review of Russian UAVs

    What is at the disposal of the Russian army these days, and what are the prospects for Russian UAVs in the near future?

    "Bee-1T"- Soviet drone, first flew in 1990. He was a fire spotter for multiple launch rocket systems. It had a mass of 138 kg and a range of up to 60 km. He took off from a special installation with a rocket booster and landed by parachute. Used in Chechnya, but outdated.

    "Dozor-85"- reconnaissance drone for the border service with a mass of 85 kg, flight time up to 8 hours. The Skat reconnaissance and attack UAV was a promising vehicle, but work has been suspended for now.

    UAV "Forpost" is a licensed copy of the Israeli Searcher 2. It was developed back in the 90s. "Forpost" has a take-off weight of up to 400 kg, a flight range of up to 250 km, satellite navigation and television cameras.

    In 2007, a reconnaissance drone was adopted "Tipchak", with a launch weight of 50 kg and a flight duration of up to two hours. It has a regular and infrared camera. "Dozor-600" is a multi-purpose device developed by Transas, which was presented at the MAKS-2009 exhibition. It is considered an analogue of the American Predator.

    UAVs "Orlan-3M" and "Orlan-10". They were developed for reconnaissance, search and rescue operations, and target designation. The drones are extremely similar in appearance. However, they differ slightly in their take-off weight and flight range. They take off using a catapult and land by parachute.

    Send your good work in the knowledge base is simple. Use the form below

    Students, graduate students, young scientists who use the knowledge base in their studies and work will be very grateful to you.

    Performing various tasks, both in the military and civilian spheres, significantly expands the range of UAVs that can be used for this purpose. It is already clear that in the near future several platforms will be required, with different types of engines and, most importantly, with different sets of on-board equipment.

    It can be noted that the most numerous class "drones", today in Russia, these are electric aircraft weighing up to 15 kg. Almost all of them are able to fly Notmore2hours, take off, as a rule, using launch devices and land, in most cases, by parachute. The relatively small take-off weight also limits the payload weight, therefore, most of these UAVs have a replaceable payload, which in itself, in this situation, is justified.

    There are a large number of problems, both in the military and civilian spheres, that can be successfully solved using such devices. These UAVs should be cheap, used by unskilled flying specialists, not require serious maintenance and be mobile without the use of special vehicles. The ground part of such a system should be simple and easy to use. Actually, this is the path that most developers of these systems follow. Given the low weight of the payload, the requirements for on-board optical and infrared sensors increase significantly. The system's sensors should perform mainly observational functions and, to a lesser extent, measuring ones.

    There is no need to create special units to operate these systems. A high degree of automation should allow ordinary specialists in both the military and civilian spheres to operate these systems.

    The next step in the classification of the use of UAVs is the creation of “drones” for conducting reconnaissance of the earth’s surface and water areas at a distance of 100 km. To perform such tasks, “unmanned” equipment must be used, capable of flying day and night, in simple and difficult weather conditions. Apparently such equipment should be able to examine the area in detail before 1000 km 2 in one flight. This can only be achieved by UAVs capable of flying for at least 10 hours. A distance of 100 km is determined by the direct radio visibility distance from a height of up to 3 thousand m, at which it is possible, without signal relaying, to ensure the transmission of streaming images in real time. It is not difficult to calculate that when flying in a straight line, with the condition of returning to the departure point, such a UAV is capable of flying to a distance of 600 km. A device capable of flying for 10 hours will have a take-off weight 100 -20 0 kg and, of course, will require a runway of at least 300 m in length, as well as maintenance by a qualified crew. Currently, such devices are capable of taking off using launch devices.

    For the military, these UAVs can be part of a reconnaissance unit of a formation such as a brigade (to be the brigade’s day and night vision), or for civilian specialists, they can be used as part of the organization that operates it. For the FSB Border Troops, such devices can be part of a unit such as a detachment and provide control over a significant section of the border, especially in high mountains, in the Far North and in conditions of maritime border protection. Transmission of video and photographic images in real time makes it possible to organize interaction with other technical means of protecting the State Border.

    Means of ground support for the operation of such complexes are formed on the basis of mobile control points (MCP), located, as a rule, on a vehicle chassis, as well as from mobile temporary control points (TCP), located in places where UAV take-off/landing is supported. The ability to place PVPU directly on the territory of the outpost allows you to receive information in your area of ​​​​responsibility in real time when a UAV flies along the border. Considering the flight duration of these UAVs, we can say that one UAV unit, consisting of one or two complexes, is capable of monitoring a section of the border up to 1000 km long.

    BYAWSmanagementby flightUAV

    The software allows you to display a video image from a forward-looking camera on the monitor of the pilot-operator's workstation and displays telemetric information. Telemetry information is displayed in the “heads-up display” mode or in the “virtual instruments” mode. The monitor also synthesizes the position of flight mission points and other spatial information that helps the pilot control the UAV’s flight along the route.

    Figure 1: Pilot-operator software frame.

    BYAWSmanagementby flightUAV allows the pilot operator to:

    Control the flight of the UAV during the route and landing;

    Change the flight mission when performing a flight in the radio visibility zone;

    Automatically receive warnings when the UAV goes beyond the established limits (flight speed, roll, pitch, flight altitude above the terrain).

    BY has an intuitive interface, protecting operators from possible errors. Modular architecture BY allows you to configure it to work on computers with different characteristics, connecting new controls or actuators.

    BYAWSoperatortargetequipment(observer)

    BY The observer's workstation (Figure 2) is designed to search for a target, capture and track a target, and issue target designation. The monitor displays video from the UAV's PTZ camera, information about the direction of the camera, information about the position of the center of the frame on the ground. Given BY allows the observer:

    Control the onboard rotating optical-thermal imaging head;

    Control the optical zoom of the camera;

    Determine the coordinates of the center of the field of view or any object in the field of view;

    Designate a target with automatic determination of its coordinates;

    Capture and track a target.

    Figure 2: Frame from observer's workstation software.

    BY processing And representation video information

    Electronicstabilizationvideo used in BY The observer's workstation provides:

    - improved video perception, especially when viewing at high magnification, when the effect of camera shake is especially noticeable;

    - reducing the quality requirements for camera hardware stabilization or completely eliminating the use of hardware stabilization, reducing the weight and cost of the surveillance system;

    - increasing the degree of image compression, which allows you to transmit data over a greater distance with better quality.

    Teleautomatescort

    The tracking teleautomatic is designed to capture and track a target. The teleautomatic device provides automatic target tracking in any real conditions: when changing the scale, viewing angle of the object, changing the illumination and contrast of the object, when the object periodically disappears from the field of view.

    Accuracydefinitionscoordinatesobject

    The error in determining the coordinates of an object identified or indicated by the operator in the image is determined by a combination of instrumental and methodological errors.

    Instrumental errors include:

    - error in determining the coordinates and altitude of the UAV;

    - accuracy of determining the heading, roll, and pitch angles of the UAV;

    - accuracy of synchronization of the moment the camera shutter is released with data from the UAV navigation system;

    - error in determining the camera position relative to the navigation system sensors (UAV center of mass);

    - error in determining camera distortion.

    The magnitude of methodological errors is affected by:

    - UAV flight altitude above the terrain;

    - distance from the positioned object (target) to the nadir point (target removal);

    - complexity of the terrain.

    Taking into account the above factors in the modern configuration of the Dozor UAV:

    Accuracy of determination of orientation angles 0.1є

    The accuracy of determining the heading angle is 1є

    Synchronization accuracy 0.1 sec

    Discreteness of information TsKRM1 ang. sec. (at the latitude of Moscow it is equivalent to 80 m)

    GNSS receiver rated accuracy:

    in plan coordinates 10 m

    in height 20 m

    At a flight altitude of 1000 m above the terrain at a speed of 100 km/h, the total error in determining the coordinates of an object located at an angle of 30° from the camera line of sight will be about 200 m(SKO).

    Increased accuracy can be achieved by reducing instrumental errors (using higher accuracy sensors as part of the navigation system), or by using an accurate pre-referenced photo map of the area, for example, a satellite image.

    We have technologies for linking to both a 2D photo map and a 3D photo map. The average overlay accuracy will be 2-3 pixels of the original map, or about 5 m.

    GluingAndcorrectionmosaicphotographic images

    As a result of area or extended survey, an array of high-resolution photographs is formed. Each photograph has a coordinate reference according to the UAV navigation system and data on the UAV orientation angles at the time the photograph was taken. Original BY allows you to automatically perform the following in the shortest possible time after the array of images is received by the NPU computer:

    - correction of color and brightness of pictures;

    - simultaneous stitching of frames;

    - orthorectification;

    - cutting maps into mosaics.

    Work productivity BY allows you to process 1000 pictures taken with a 12 megapixel camera in 1 hour.

    Figure 4: Stitching together a survey of an extended object.

    Application options

    The above tactical and technical characteristics of the Dozor series UAVs and the characteristics of their on-board systems allow the use of UAVs for aerial reconnaissance purposes as an aviation component that provides:

    - 24-hour surveillance of the battlefield;

    - intelligence secrecy;

    - the ability to conduct reconnaissance in low cloud conditions;

    - safety of personnel.

    Patrolling

    Regular patrols are carried out along a given route.

    To illustrate the use of UAVs within radio visibility, a UAV patrol route was constructed along the state border of the Russian Federation based in the area of ​​Orsk (Figure 5). When designing the route, the specified range of the Dozor-85 UAV command radio link (up to 100 km) was taken into account. Thus, the initial and final PPM are removed from the take-off point (TPL) by 65 km and 61 km, respectively. The length of the patrol route is 135 km, and the flight time at a patrol speed of 100 km is 1 hour 30 minutes (taking into account the curvature of the trajectory). Taking into account the flight time at a speed of 150 km/h, the total time on the route will be 2 hours 20 minutes (total length of the route 235 km).

    Drawing6 reproduces a patrol route based on the limitation of the maximum flight duration of the UAV. The total length of the route will be 615 km (5 hours 30 minutes), including the length of the patrol zone 355 km (3 hours 30 minutes). It should be emphasized that, when performing a flight mission on a route of maximum operational length, the UAV does not have the opportunity to fly over any point at the operator’s command, being outside the radio visibility zone, and complete the execution of the mission. Depending on the “delay” time, the route must be shortened, and at the final waypoints, overflying the area is impossible.

    Concentric circles with radii:

    · 50 km from the starting point approximately corresponds to the reachable zone within 1 hour from the moment the combat order to use the UAV is received

    · 100 km corresponds to 1 hour 15 minutes

    · 200 km - maximum operational range

    Terrain reconnaissance

    Drawing7 illustrates the use of UAVs for reconnaissance of terrain for 1 hour at the maximum operational range. The maximum remoteness of the reconnaissance area is 350 km. At a flight speed of 150 km/h, the UAV will reach the patrol zone in 2 hours 20 minutes, can remain in the zone for 1 hour and return to the starting point. The total flight duration will be 5 hours 30 minutes.

    UAV flight planning in mountainous conditions is carried out using digital terrain maps (DTRM). Freely available commercial CCRMs obtained from satellite imagery provide sufficient accuracy in determining the height of the terrain in combination with precise coordinate reference.

    Experience applications UAV "Watch- 90 E » V mountain terrain

    In 2008, a trial operation of the complex with the Dozor-90 E UAV was carried out in the interests of the Border Service of the FSB of the Russian Federation (Figure 8). In the period from October 15 to October 19, 11 UAV flights were carried out with a total duration of 5 hours 30 minutes. The flights were carried out in the daytime in simple and difficult weather conditions, with wind speeds at the surface of the earth: headwind - 15 m/s, sidewind - 10 m/s, tailwind - 5 m/s. The takeoff was carried out from a site located at an altitude of 1000 m above sea level, the maximum flight altitude of the UAV was 3000 m.

    In operation, the Dozor-90 E UAV showed high flight and operational qualities; all systems of the complex operated normally.

    Based on the results of the flights, a photographic map of the flight area was compiled along the border of the Russian Federation (Figure 8).

    Figure 8: UAV landing on an unprepared site in the outpost area

    Applications of UAVs in the coastal zone

    The scenario of ground-based deployment of a complex with a UAV and reconnaissance over sea waters at the operational range of the UAV is considered.

    Standard optical means of UAV target equipment can be used for short-range reconnaissance and target identification.

    Currently, the main technical component of monitoring the situation at maritime borders is technical observation posts (TSP), which are a network of coastal radar stations. The target detection range of the PTN radar is up to 25 km. This is approximately the distance of one PTN from another. The use of UAVs in conjunction with PTN will allow:

    1) significantly increase target detection range;

    2) reduce the target identification time.

    Patrollingcoastalzones

    When patrolling in the coastal zone, the UAV route is laid along the coastline beyond the range of the PTN radar. In addition to standard equipment, PTNs are equipped with communication equipment with UAVs. Thus, when flying around a route, the UAV is constantly in contact with the nearest PTN, transmitting video and photo information to it.

    At the same time, UAVs are capable of identifying a detected target using optical surveillance means, approaching the target at a close distance. In this case, the target can be detected either directly by the UAV or by any of the STVs of this network. In the second case, the UAV, at the operator’s command, flies to a given area, interrupting the route, or rising from its home base.

    Intelligence serviceremotegoals

    To conduct reconnaissance of remote targets, Dozor UAVs can be used autonomously, similar to use at the maximum operational range (Figure 8).

    Working outside the radio visibility zone of its NPU, the UAV equipment registers all the information of the target equipment in the on-board storage devices. Data analysis is carried out after returning to base. In another embodiment, information is transmitted in real time to a ship located in the direct radio visibility zone from the UAV. Thus, target detection and identification is carried out using on-board optical-electronic surveillance systems.

    ApplicationUAVtogetherWithremotelymanageableby boat

    We have been working on issues of interaction between sea and air remote means for conducting reconnaissance over the seas.

    The following algorithm for the integrated use of funds is proposed (Figure 9):

    Figure 9: Integrated use of remote reconnaissance systems.

    · a UAV performing a reconnaissance flight detects a target and transmits its coordinates to the control post via a communication channel with the PTN;

    · a decision is made to exert influence;

    · a remotely controlled boat is sent to the area with given coordinates;

    · while the boat is moving, the UAV continues to track the target, guiding the boat;

    · Having reached the target, the boat exerts influence on the target, fixing the coordinates and time. Real-time data is transmitted using UAVs to PTN and NPU.

    It is also relevant to use such complexes in the fight against poachers, for example, in the Astrakhan floodplains and in the fight against drug trafficking in certain areas of our country.

    The ground equipment of such complexes allows the deciphering operator to recognize targets and issue the coordinates of found objects with a high degree of accuracy. The user of such a system decides how to use the obtained coordinates.

    Let us show, using the example of a decoder complex developed by Transas Vision, how this process can occur:

    Intellectualcomplexdecryptionimages

    The complex is designed to connect the UAV, as a source of information, to the consumer.

    The complex allows you to connect one or several UAVs to the consumer at the same time.

    Preparation, selection and delivery of formalized messages

    When the desired object is detected, the operator’s monitor displays an image of the object, information about it (type of object, coordinates, speed, etc.) and options for action for the type of object found.

    When the operator selects one of the actions proposed by the system, a formal message is automatically generated.

    The operator can also initiate the issuance of a formal message by indicating the position and type of object in the image.

    Documentation

    The software of the complex also automatically records in the database all operator actions and all formal messages issued by the system.

    The software of the complex can also provide all or any part of the incoming or processed information to a higher level of the control system for its display and analysis.

    The ground equipment of such complexes allows the deciphering operator to recognize targets and issue the coordinates of found objects with a high degree of accuracy. How to use the received coordinates, decidesmyselfconsumersuchsystems.

    The Dozor-100 UAV is a development of the Dozor-85 UAV in the direction of increasing the flight duration and range.

    The extended wing made it possible to improve the flight quality of the airframe and, consequently, reduce fuel consumption during cruising flight. Thus, the flight duration of the Dozor-100 UAV increased to 10 hours with a large payload weight.

    The exhaust system is hidden inside the fuselage, which reduces thermal signature in flight and reduces exhaust noise. Placing the power plant in the aft part of the airframe allows for a rational arrangement of the UAV payload and frees up space for placing antenna devices of various types. The use of a V-shaped tail ensures correct alignment of the airframe when placing the engine in the tail of the UAV fuselage.

    ControlUAV"Watch"

    The UAV is controlled from a mobile control point ( MPU) from the pilot-operator's workstation or a mobile temporary control point ( PVPU). UAV " Watch» are equipped with a modern flight navigation system (FNS) with an automatic control system. The PNC includes:

    - an inertial system integrated with a global navigation satellite system (GNSS) GLONASS/GPS receiver, providing determination of coordinates, flight altitude, heading angles and orientation of the UAV;

    - an air signal system that provides determination of airspeed and barometric altitude;

    - low altitude radio altimeter;

    - an autopilot module that provides control commands to the UAV flight controls.

    AWSpilot operatorUAV

    3 UAV control modes are implemented:

    Directmanualcontrol according to species information coming from a forward-looking video camera. In this mode, the pilot operator controls the UAV and directly acts on the controls, as if he were in the cockpit. The mode is used in the near zone to bring the UAV onto the landing glide path and when landing in manual control mode. The technology used is to display on the windshield information received via telemetry channels from the UAV navigation and flight system (HUD - head-up display).

    Vectorcontrol allows the pilot operator to influence the UAV through the autopilot: change the altitude and speed of flight, perform a turn in a given direction, fly around a point and other standard flight procedures.

    Autoflight is the main method of controlling a UAV and is carried out under the control of an autopilot along a route determined by a given sequence of turning points (RPM). During the flight, the pilot operator can interfere with the operation of the autopilot by issuing the following commands:

    - introduction of new planning points;

    - loading a new flight route;

    - cancellation of the flight mission and command to return the UAV;

    - command to fly over a given point or loiter over a certain area.

    Before the flight, a flight mission (PO) is drawn up in the form of a route determined by the coordinates of the turning points. A scanned map, aerial photographs, or satellite image can be used as a cartographic background. For flights in mountainous areas with difficult terrain, it is necessary to take into account the features of the terrain, both when planning the flight route and when placing a ground tracking station. The flight mission is saved in the memory of the MPU computer and a route database is formed. Upon completion of the drafting of the PP, the program automatically checks it for “feasibility”, taking into account the specified characteristics of the UAV.

    PO planning screen.

    Upon completion of the route, the UAV arrives at the final destination of the route, where it makes an automatic approach and lands like an airplane under the control of a pilot operator.

    The standard configuration of the MPU consists of two workstations: the pilot and the payload operator. A mobile execution of the workstation on a tablet computer is possible, allowing you to transfer information from the UAV directly to the consumer:

    Portable UAV control computer.

    Auxiliarywaysnavigation

    The following methods are considered as auxiliary means of UAV navigation if it is impossible to use GNSS information:

    Airborne coursedead reckoningcoordinates allows you to determine the distance traveled and direction using data from the airspeed sensor and the inertial system (or magnetic compass) as a heading sensor.

    Communication systems

    Onboard communication equipment of the UAV " Watch"(data transmission lines - LTD) provides two-way transmission of data and control commands, as well as real-time transmission of video information from the board to the base station.

    The data channel transmits:

    From "board" to "ground"

    · Telemetric information (coordinates, speed, flight altitude);

    · Information about the status of on-board systems.

    From "ground" to "board":

    · Flight control commands: changing the route, returning, changing flight parameters (speed, altitude, etc.);

    The next type in the UAV line should be medium-altitude UAVs with long flight duration. The military from the Ministry of Defense should first of all be interested in such UAVs. This group of “drones” is very close in its functionality to such well-known UAVs as the “Predator” from the USA. One of the features of these “drones” is the presence of a strike function.

    An analysis of the targeted use of spacecraft and tactical combat systems with unmanned aerial vehicles (UAVs) during the operation to force Georgia to peace in 2008 showed that in its existing form, none of these means is the only sufficient one to meet the requirements of troops in geo-intelligence information .

    The functioning of high-precision weapon systems (HPE) requires not only technical means with highly sensitive sensors and high-speed signal processing facilities, but also appropriate information support, as well as a developed telecommunications network that meets modern requirements.

    The information and intelligence infrastructure being created must provide, in a time scale close to real time:

    Search, detection, recognition, identification and location of targets;

    Formation of the necessary electronic information documents (target forms) for individual flight missions for weapons;

    Assessing the results of strikes.

    Rapid changes in the operational environment require immediatelyOth response and timely adjustment of tasks to the involved forces and means, especially when working with moving targets.

    In addition, in the interests of the WTO, it is necessary to ensure the accuracy of determining the coordinates of the affected objects: no worse 5 - 7 m- for strategic and 3 - 5 m- for operational-tactical command and control levels of the RF Armed Forces.

    If in the interests intelligence If the highest image resolution is required, then it is in the interests of WTO It is also acceptable to use medium resolution images (3 - 5 m).

    For the purpose of continuous information support (IS) for the application of WTO, the US Armed Forces are actively using strategic reconnaissance unmanned aerial vehicles, mainly large ( more24 hours) flight duration - high-altitude UAV RQ-4A " GlobalHawk"and mid-altitude MQ-1B" Predator".

    These devices are designed to conduct airradarAndoptoelectronicintelligence in order to support the actions of the Air Force and other types of armed forces in various theaters of operations, they are capable of transmitting data in real time to ground command posts.

    To quickly obtain geospatial information together with reconnaissance satellites offered use complexes with UAVs.

    When using high-resolution satellite images as a topographic image to superimpose current intelligence information, a significant increase in the accuracy of determining the coordinates of objects is achieved. Company"R.E.T.Kronstadt" has binding technologies, both 2 D-photo map,SoAndTo3 D-photo map.

    To increase the accuracy of target designation, the Transas-Vision company has developed a program TopoTarget. The program automatically stitches the resulting photo with a photo card.

    In the case of undefined (flat) relief, the program provides subpixel stitching accuracy, while accuracy target designation corresponds to the accuracy of the photo map.

    Principleworkprograms

    Before the flight, the TopoTarget program processes a photo map of the flight area, automatically identifying characteristic points on it. The identified characteristic points are entered into a database, then the database is ordered. The photo map can be taken from any aircraft or satellite. Basic photo card requirements:

    The photo map should be taken at approximately the same time of year as the flight time.

    The resolution of the photo card must be such that the stitched frame occupies an area of ​​at least 800x600 pixels.

    When receiving a photograph, the program automatically finds characteristic points in the photograph, the corresponding points in the database compiled during processing of the photo map, selects a self-consistent set in the set of correspondences, and stitches the resulting photo with the photo map.

    Interfaceprograms

    The result of the program is shown below: the photo map was compiled based on the results of aerial photography of 25 frames. Attached to the map is a frame that was not included in the 25 from which it was compiled.

    The following example shows a tank located on a framed frame.

    Performance

    To speed up the program and eliminate errors, telemetry data is used when filing a frame: matches are searched on the photo map within a given radius from the center of the frame.

    Complexes with UAV type "Watch" have a number of significant advantages compared to domestic analogues.

    At the enterprises of JSC " Transas“The technical groundwork has been created, there are flying prototypes and a production base has been deployed to create prototypes of such complexes.

    Along with this, JSC "Transas" has experience in creating training complexes, which will make it possible in the future to organize training for personnel in managing complexes with UAVs.

    UAV "Dozor-85" And "Dozor-100" According to their technical characteristics, they belong to medium-range aircraft. The development used technical solutions similar to UAVs « Shadow-200" And " Predator" According to the characteristics of the UAV target load "Dozor-85"And"Dozor-100" capable of performing the same tasks as the mentioned foreign systems with the exception of drums. Smaller weight and size characteristics were achieved through the use of modern technologies, while foreign analogues were developed in the 90s of the last century.

    In the basic configuration, a complex with a UAV "Watch" can be supplied as part of three aircraft and a mobile control center located on the chassis of an all-terrain vehicle.

    UAV complex " Watch» can be quickly delivered to the area of ​​application using transport aircraft, railway transport, and waterways. The complex is mobile, and its operations require a minimally prepared site: a dirt strip, a lawn, compacted snow. The complex is moved using an all-terrain vehicle with a trailer.

    Periodic maintenance is carried out by trained personnel directly at the base site. Spare parts and necessary tools are supplied included.

    The complex is operated by a crew of four to five people.

    Complex with UAV "Watch" is fullyautonomous. All units and systems are located on one chassis. The base station systems are powered by a motor-generator; the UAV batteries are recharged using a charger included with the UAV from the vehicle's on-board power supply.

    Considering the growing interest of companies in the fuel and energy complex, Russian Railways, the Ministry of Emergency Situations and other departments in the information that can be obtained using complexes with UAVs, it is necessary to provide for the option of a public-private partnership.

    These complexes with UAVs should primarily be created according to a principle that takes into account the dual use of UAVs. At the same time, the customer of such UAVs may be financial and industrial groups interested in using the resource of these complexes in peacetime together with the RF Armed Forces. In the process of implementing such projects on the basis of public-private partnership, the resources and contributions of the parties, as well as financial risks and costs, are consolidated and combined. The results achieved are distributed between the parties in predetermined proportions.

    Not long ago, information appeared in the open press about US plans to build a UAV before2047 of the year. Analyzing this material, we can once again state the fact that we are still significantly behind the current level of UAV development.

    So in this program it is noted that the main emphasis in the development of UAVs will be on devices like PREDATOR and similar devices of later modifications. All UAVs are divided into several groups and each group specifies what equipment the UAVs must carry and what technical specifications they must achieve.

    In our country, a device similar to a UAV has not yet been created at all. PREDATOR. The first attempts to create such a device by the Vega concern under the program "Prokhodchik" turned out to be unsuccessful. Yes, to be honest, the designed device can hardly be called an analogue of a UAV PREDATOR. Neither in range, nor in payload, nor in flight duration does this project significantly fall short of the UAV PREDATOR, I’m not even talking about the lack of a training system for managing such UAVs and the lack of simulators for training operators for them.

    In the current situation, we need a UAV that is functionally equal to the PREDATOR UAV, and such a UAV does not necessarily have to be close in size to it.

    Let's calculate the weight of the load that needs to be lifted into the air in order to perform the functions of a UAV PREDATOR(let's exclude the shock function for now).

    OTG (optical-thermal imaging head) - 5 kg,

    Photo complex - 4 kg,

    AVOVP (analog video take-off/landing system) -1 kg,

    LTD (data line) - 0.7 kg,

    KRL (command radio line) - 0.3 kg,

    AP (autopilot) - 0.4 kg,

    SINS (on-board inertial system) - 0.6kg,

    Radar (radar station) - 4 kg.

    Total: 16 kg.

    Is it a lot or a little? Certainly,Nota lot of. This is the real weight that today is capable of lifting a UAV with a maximum take-off weight 100 - 150 kg and this is provided that he must have enough fuel on board 10 hoursflight.

    In order to fulfill this condition, the design bureau of ZAO "R.E.T. Kronstadt" designed a UAV " Dozor-100» which is based on the wing design with a center section.

    "Dozor-600" and its prototype "Dozor-100" at the MAKS-2009 exhibition.

    IN UAV "Dozor100" an engine from a German company is used " 3 W» stamps "210T.S.» . Rated power of such an engine 21.2 hp. When using a shaft generator rotating from an engine, we lose up to 10% of engine power. Thus, the available capacity of our power plant is 19 hp. From design theory it is known that the acceptable load per unit hp. for low-maneuverable aircraft lies within 6-7 kg per hp Therefore, if we take the load in 6 kg per hp, then max. take-off weight will be 114 kg, and when 7 kg per hp this figure will be equal 133 kg.

    Considering the fact that we take into account the engine power based on the engine manufacturer’s passport data, in the calculations we decided to limit the take-off weight to 1 1 0 kg, at the same time, strength calculations were performed for weight 130 kg. That. We have a reserve in terms of UAV strength.

    At take-off weight of 110 kg we can take on board 40 kg of fuel, in our case it is 54 liters. The maximum fuel consumption obtained during the operation of previous Dozor UAVs with these engines was 5 l/hour. Consequently, we have a fuel reserve that allows us to fly for at least 10 hours at a cruising speed of 120-140 km/h. Accordingly, if there is no wind, we are able to fly 1200-1400 km. Such figures give us the opportunity to conduct reconnaissance for 4-5 hours at a distance of 400 km from the take-off/landing airfield.

    That. the task assigned to the UAV in the topic "Prokhodchik" achieved by using UAVs "Dozor-100".

    Now let's remember that the UAV PREDATOR also performs a shock function, because capable of carrying 300 pounds of external sling load on the wing. This is the function for UAVs " Dozor-100" is not feasible. 300 feet is 120 kg and this is absolutely impossible. Therefore, for a UAV with an impact function, it is necessary to design another UAV.

    Glider UAV"Watch-100", made almost entirely from composite materials. Wingspan - 6.0 m; total take-off weight - 110 kg; power plant - two-stroke engine with a power of 21.2 hp; flight duration - up to 10 hours; cruising altitude 300-1500 m, ceiling 4000 m.

    UAV "Dozor-100" took part in exercises in 2009 "West-2009" in Kaliningrad, where he carried out the task of searching for radio patrol ships of NATO countries located in neutral waters during exercises. The task included transmitting images of the found ships and the coordinates of these targets to the exercise control command post.

    Map of the exercise area with search sectors for ships.

    UAV "Dozor-100" took off from the airfield "Donskoye", located in 20 km from the command post, where the control vehicle with the NPU was located, and flew to neutral waters. In search mode, it flew 200 km in neutral waters, transmitting images over a distance of 55 km in real time. Based on the received images and coordinates, the decryptor operator compiled and transmitted reconnaissance. report to the fleet commander. That. For the first time, a UAV transmitted video images over a distance of more than 50 km.

    Together with representatives of OJSC "Research InstituteTP" The possibility of obtaining target coordinates in real time and transmitting them over a distance of more than 50 km was demonstrated.

    The control of the UAV in takeoff and landing modes was carried out from a mobile temporary control point (TCP), located 20 km from the control vehicle, and this confirmed the correctness of the chosen concept - a takeoff and landing airfield remote from the theater of military operations.

    To complete the assigned task, the UAV "Dozor-100" in total, flew in real conditions more than 300 km in each flight, while the flights were carried out under conditions of intensive use of naval combat aviation, in difficult weather conditions (cloud height 500 m, visibility 2-3 km, side wind - up to 11 m/sec) .

    Simply uncovering goals today is not enough. We need to determine their coordinates (“bind”Togeographic informationfundamentally) with the accuracy required for the application high-precision weapons. Satellite-corrected missiles and bombs ensure accurate hits 5-7 m with the prospect of improvement to meters. It must be appropriate target designation. The entire UAV monitoring system is aimed at such precise alignment.
