Description

The invention relates to systems of combat unmanned aerial vehicles designed to protect airspace and territories and defeat air and ground intruders.

There is a known system of combat unmanned aerial vehicles (Minefields in the air // “Technology for Youth” 1938. No. 2. P. 19), which is a set of missiles, to the bodies of which springs are rigidly attached at one end. Ammunition is installed at the other ends of the springs. Steel cables are attached to the ammunition at one end, and the other ends of the cables are attached to parachutes. When air intruders approach, the missiles are launched to the desired altitude of tens of kilometers and eject ammunition using springs, the parachutes of which open. As a result, the noted ammunition begins to slowly fall to the ground, and the steel cables unwind under the influence of gravity and are positioned perpendicular to the surface of the earth. Thus, unique “air minefields” are formed. If an aerial intruder touches the steel cable, the ammunition hits it and explodes. All ammunition is equipped with automatically operating fuses that prevent explosion when falling to the ground. The rocket bodies descend to the ground using their parachutes. Thus, both missiles and unexploded ordnance can be reused.

The disadvantage of this system of combat unmanned aerial vehicles is that its operation time is limited by the time the ammunition is lowered to the ground.

There is a known system of combat unmanned aerial vehicles, chosen as a prototype (Novichkov N., Fedyushko D. “Swarm” of drones. New combat tactics of China’s unique weapons // Military-Industrial Complex News. TASS [Electronic resource], - Access mode: https:// vpk.name/news/234717_roi_bespilotnikov_novaya_taktika_boevyh_deistvii_unikalnogo_oruzhiya_kitaya.html (date of access: November 15, 2018)) and is a system - a swarm of impact multicopters with electric motors and power supplies, on the shafts of which propellers are located, each multicopter ter is equipped with a small-sized spherical gyro-stabilized optical- electronic platform, search and targeting radar and other reconnaissance equipment, as well as various airborne weapons, for example, parachute submunitions, shells, guided missiles, aircraft bombs, grenade launchers, machine guns and other weapons. Impact multicopters are equipped with a multi-channel data transmission line.

Tactical scenarios for the combat use of a swarm of attack multicopters include the destruction of armored vehicles and various vehicles, enemy strike formations, artillery, radar stations, technical positions and warehouses, communication centers, personnel, aircraft in shelters, and power supply points. Attack multicopters with air-to-air missiles are also capable of attacking aerial targets such as drones, helicopters, etc. A swarm of attack multicopters can operate within a radius of 30 kilometers and stay in the air for one hour.

The main disadvantage of the prototype is the short operating time, determined by the capacity of the power supply of electric motors.

The objective of the present invention is to increase the operating time of a combat unmanned aerial vehicle system through the use of an induction method for transmitting electrical energy.

The technical result is achieved by the fact that in a system of combat unmanned aerial vehicles containing unmanned aerial vehicles, in the housings of which electric motors connected to power sources are rigidly fixed, propellers are located on the shafts of the electric motors, each unmanned aerial vehicle is equipped with a small-sized spherical gyro-stabilized optical-electronic platform, search and targeting radar station, reconnaissance and navigation unit, multi-channel data transmission line device, receiver-transmitter of “friend or foe” equipment, weapons of destruction are rigidly fixed on the body, electrical windings are rigidly fixed on the propeller blades of the unmanned aerial vehicle, which are galvanically connected to power sources, combat unmanned aerial vehicles are designed to interact with unmanned aerial vehicles-refuelers, in the lower part of the body of which a magnetic field source is rigidly fixed, a permanent magnet is used as a magnetic field source, or an electric coil with a winding is used as a magnetic field source connected to the power source.

The system of combat unmanned aerial vehicles is illustrated by drawings. Figure 1 shows the design of an unmanned aerial vehicle and a refueling unmanned aerial vehicle at the moment of transmitting electrical energy by induction. Figure 2 shows an embodiment of an unmanned aerial vehicle refueling using permanent magnets as a source of magnetic field, and figure 3 shows the design of an unmanned aerial vehicle refueling with an electric coil with a winding.

The system of combat unmanned aerial vehicles contains unmanned aerial vehicles 1, for example, multicopters, quadcopters or tiltrotors, in the housings 2 of which electric motors 3 are rigidly mounted, for example, AXI 2814/22, 037 or Racer star Racing Edition 2306 2700KV or Readytosky 2205-2300 2300KV or Racer star Racing Edition 2205 2300KV. Electric motors 3 are connected to power sources 4, for example lithium batteries LP2-22-xHSw, LP4-22-xHSw or LP6-30-xHSw. On the shafts 5 of electric motors 3 there are propellers 6. Each unmanned aerial vehicle 1 is equipped with a small-sized spherical gyro-stabilized optical-electronic platform 7, for example, “Genesis U200”, “Genesis LE-350” or “Genesis SGC”, search and targeting radar station 8 , reconnaissance and navigation unit 9, multi-channel data transmission line device 10, receiver-transmitter of “friend or foe” equipment 11, for example, the “Password” system (RF) or the Mk12 system (USA), as well as various means of destruction 12, for example, parachute submunitions, projectiles, guided missiles, aerial bombs, grenade launchers, machine guns.

On the blades 13 of the propeller 6 of the unmanned aerial vehicle 1, electrical windings 14 are rigidly fixed, which are galvanically connected to power sources 4, and for unmanned aerial vehicles refueling 15, a magnetic field source 16, for example, samarium-cobalt, is rigidly fixed in the lower part of the body 2. neodymium permanent magnets 17 (Fig. 2) or an electric coil 18 with a winding 19 connected to a power source 4 (Fig. 3).

The operation of the combat unmanned aerial vehicle system is carried out as follows.

After take-off and arrival of the unmanned aerial vehicles 1 into the combat duty zone, the coordinates of which are determined by the flight mission, the unmanned aerial vehicles 1 “freeze” in their positions. Reconnaissance and navigation unit 9 performs the following functions: flight along a given route; changing the route assignment or returning to the starting point upon command from the ground control station; fly around a specified point; automatic tracking of the selected object; stabilization of orientation angles of an unmanned aerial vehicle; maintaining specified altitudes and flight speeds; collection and transmission of telemetric information about flight parameters and operation of target equipment; software control of target equipment devices.

When the unmanned aerial vehicle “hovers,” the spherical gyro-stabilized optical-electronic platform 7 provides round-the-clock monitoring of the terrain, detection and further observation of targets that appear in the combat duty zone.

The transfer of information between the unmanned aerial vehicle 1 and the ground control point (not shown in the drawing) is carried out by a multi-channel data line device 10.

The search and targeting radar station 8 provides surveillance and target detection, automatic and continuous tracking of the attacked target in range and angular coordinates. In this case, the receiver-transmitter of the “friend or foe” equipment 11 recognizes the target by sending a request. If the correct response signal is not received, means of destruction 12 are initiated.

In the event of a discharge of the power source 4 to a level that does not ensure the normal functioning of the unmanned aerial vehicle 1, the device of the multi-channel data transmission line 16 sends a signal to the ground control point, through which a combat unmanned aerial vehicle tanker 15 is sent to the location of the unmanned aerial vehicle 1. exchange of request and response signals from “friend or foe” equipment 11 between the unmanned aerial vehicle 1 and the unmanned aerial vehicle refueling 15. The unmanned aerial vehicle refueling 15 flies up to the unmanned aerial vehicle 1 and “hover” over it. The magnetic field created by the magnetic field source 16, which is rigidly fixed in the lower part of the body 2 of the unmanned aerial vehicle-refueling vehicle 15, meshes with the electrical windings 14 located on the rotating blades 13 of the propeller 6 of the unmanned aerial vehicle 1. According to the law of electromagnetic induction in electrical windings 14, an electromotive force is induced, under the influence of which an electric current arises, charging the power source 4 of the unmanned aerial vehicle 1. After the charging process is completed, the unmanned aerial vehicle-refueling vehicle 15 flies to the next unmanned aerial vehicle 1.

After the charging process is completed, the tanker unmanned aerial vehicle 15 flies to the next unmanned aerial vehicle 1 or returns to the base.

As you can see, charging the power source 4 of the unmanned aerial vehicle 1 by a non-contact inductive method without interrupting its flight allows an unlimited increase in the operating time of the combat unmanned aerial vehicle system.
