Description

Technology area

The invention relates to the field of capturing small-sized unmanned aerial vehicles (UAVs) and can be used in military equipment.

Prior art

Various technical solutions are known for capturing a UAV target in the air using a trap network, which is compactly packed in an interceptor UAV.

The known method is described in the patent of the Russian Federation No. 150610 for the utility model "Device for capturing small-sized unmanned aerial vehicles", IPC: F41H 11/02, Application: 2014107027/11, priority: 02/25/2014, published 02/20/2015, authors: Sergey Shishkov Viktorovich (RU).

A device for capturing MBLA is launched when an enemy MBLA is detected by a multi-channel detection tool, or starts capturing while patrolling the space. Using all-round cameras, the device for capturing the MBLA is oriented so as to enter the enemy MBLA from the tail from above. The device equalizes the flight speed, its own and that of the enemy, choosing a certain range. The processor gives a command to shoot one of six nets located in special compartments that open at the bottom of the fuselage. The net with an integrated fastener in the middle and a parachute compartment is fired using pyrotechnic cartridges. Sinkers provide network deployment to capture MBLA. High-strength polymer threads and equalized flight speed of the device for capturing and MBLA of the enemy provide high accuracy and range of the network. At the moment the enemy's MBLA is enveloped by a net, the sinkers get tangled on one of the enemy's MBLA sides. There is a sharp drop in MBLA. A high-strength thread is pulled between the net and the attachment device in a special compartment, while the parachute opens and begins to slow down the descent of the captured MBLA. The developed device transports to the programmed area or selects the most favorable terrain for the successful evacuation of the captured enemy MBLA and continues to patrol the space. In the event of a miss, the attachment device releases the net, and the device for capturing the MBLA repeats the attack, and fires a second shot from another compartment at the enemy MBLA.

Signs that coincide with the essential features of the claimed invention are - a network with a built-in fastening element in the middle and a parachute compartment is fired, the sinkers ensure the deployment of the network to capture the MBLA, when the enemy MBLA is covered by the network, the weights get entangled on one of the sides of the enemy MBLA. There is a sharp drop in MBLA. A high-strength thread is pulled between the net and the fastening device in a special compartment, in case of a miss, the fastening device releases the net, and the device for capturing the MBLA repeats the attack, and fires a second shot from another compartment at the enemy MBLA.

The disadvantage of this device is that the capture can only be made at a low-speed or stationary air target, for example, by a hovering quadcopter. In the case of a high-speed target, the proposed method is ineffective both in aiming the MBLA itself at the target, and in the efficiency of its capture when the target moves in parallel with the dropped network.

There is also known a method described in the patent of the Russian Federation No. 72754 for a useful model "Device for combating remotely piloted (unmanned) aircraft", IPC: F41H 13/00, Application: 2007139175/22, priority 22.10.2007, published 27.04.2008, authors : Parkhomenko A.V., Molokhina L.A., Pushkin V.A., Ustinov E.M., Belyakov V.A., Shishkov S.V. (RU).

The trap net is located in the container. Weights are attached to the edges of the net on keeper tapes. The trap is delivered to the area where the UAV is located using a delivery device (for example, a rocket), where it is guided to the UAV using a guidance device. Then the trap net with sinkers is fired towards the target. In this case, the sinkers stretch the trap net, ensuring that the RPV is covered with the trap. The RPV direction finding process is carried out by a passive two-channel (sound-thermal), that is, a hidden method. The size of the net determines the amount of compensation for aiming errors, and the size of the cells and the material of the net determines the target to be captured. Round bullets of probing cartridges ZP-1 and ZP-2 for a wind gun of the VR-2 type are used as weights, fired to a height of 150 and 200 m, respectively. Bullets have holes for fastening keeper tapes. A network is attached to these tapes. The device can be used for its intended purpose from below from above.

Signs that coincide with the essential features of the claimed invention are - a trap network is placed in a container, sinkers are attached to the edges of the network, the trap is delivered to the area where the RPV is located using a delivery device, directed at the RPV, the trap network with weights is shot towards the target, when In this case, the sinkers stretch the trap net, ensuring that the RPV is covered by the trap.

The disadvantage of this method is that after the container with a trap network is delivered to the area where the RPV is located, its guidance by the sound-thermal method seems to be ineffective, taking into account the sound-thermal parameters of modern UAVs, for example, with an electromotive propulsion or flying in a gliding mode. In the case of a high-speed target, the proposed method is ineffective both in guiding the RPV itself to the target, and in the efficiency of its capture when the target moves in parallel with the dropped network.

There is also known a method of target acquisition, described in patent No. 2495359 for the invention of the Russian Federation "Device for the destruction of remotely piloted (unmanned) aerial vehicles (RPV)", IPC: F41H 11/02, Application: 2012120112/11, priority 15.05.2012, published 10.10. 2013, authors: Chistyakov N.V. (RU).

When approaching the target of the RPV, the operator, using the surveillance cameras at a distance of less than 500 meters, guides the aircraft of the RPV at the target - the RPV. The operator equalizes the flight speed and overtakes the RPV target. When a displacement sensor located in the tail section of the RPV enters the range, the onboard processor (not shown in the drawing) automatically gives a command to eject the parachute. An automatic lock opens. The lid is folded back, and the spring throws out the parachute. The displacement sensor is set to a certain distance, and its range of action is limited by the diaphragm. At the moment of filling the canopy of the parachute, the engine of the fighter operates at maximum power, and at the end of the filling of the canopy, the canopy is fired from the actuation of the parachute separation device. The target of the RPV hits the canopy of the parachute, loses speed and ability to fly and control, and the lines of the parachute reliably hold the target of the RPV inside the canopy.

Signs that coincide with the essential features of the claimed invention are: guidance of a remotely piloted aircraft (RPV), placement of the parachute in a container with a lid, filling the parachute canopy with air, the RPV target enters the parachute canopy, loses its speed and ability to fly.

The disadvantage of this device is that targeting by radar in azimuth is ineffective for targeting a maneuvering high-speed target. It is also unlikely that the target will be ahead of the target for the release of the parachute on its way and the capture of the maneuvering target by the parachute.

As a prototype, a patent for a useful model of the Russian Federation No. 185949 "Device for combating unmanned aerial vehicles" was chosen, IPC: F41H 13/00 F41H 11/04; B64D 1/00 (2006.01); Application: 2018131051, priority 08.10.2018 published on 15.11.2018, authors: Neskin A.G. (RU), Bzita V.I. (RU), Zelenov A.N. (RU), Sokolov M.JI. (RU), Podgornov V.A. (RU), Kipkaev A.E. (RU),

When an unmanned aerial vehicle (UAV) of the enemy is detected, the ground system of the multichannel means gives the command to launch the rocket. According to commands from the ground, the rocket is oriented so as to enter the enemy UAV from the nose from above. The guidance unit fixes the target - the UAV and captures it and corrects the movement of the rocket. When the rocket approaches a predetermined distance to the UAV, at the signal of the non-contact target sensor (not shown), a command is sent to the net throwing unit and the net is fired - a trap towards the UAV. The net throwing block - traps works as follows. The command from the electronic guidance unit goes to the starting control unit battery, from where the voltage is fed through the wire to the igniter. From the igniter, a hot stream of gases and particles ignites a propelling powder charge, during combustion of which gases are released and pressure builds up in the front of the chamber. Under the action of this pressure, the washer is compressed and the channels of the barrels with the projected weights open. Weights are thrown, stretching the trap net into the required shape, providing cover and capture of the UAV. Net - the trap immobilizes the UAV.

Signs that coincide with the essential features of the claimed invention are: when the rocket approaches a given distance to the UAV, a command is sent to the net throwing unit and the net is shot - a trap in the direction of the UAV, loads are thrown, stretching the trap net into the required shape, providing cover and UAV capture, net - the trap immobilizes the UAV.

The disadvantage of this method is that as a result of shooting the trap net, only the net is opened, its movement in the direction of the rocket's flight practically stops due to air resistance and braking of loads. Thus, the capture of an enemy UAV can only occur if it is directed directly into the net and does not maneuver. That is, the volume of airspace in which the UAV can be captured by the network is actually reduced to the projection of the network, which is clearly not enough.

Disclosure of the invention.

The problem to be solved by the claimed invention is to increase the likelihood of capture by the network of an aerial UAV target (unmanned aerial vehicles).

The technical result achieved when solving this problem is to increase the area of the network in its expanded form and move it in the direction of the UAV interceptor flight, maintain the balancing of the UAV interceptor after ejection of the network, and eliminate the collision of the UAV interceptor with the UAV target.

The specified technical result is achieved by the fact that in the method of capturing an air target with a network containing the approach of an interceptor UAV with a network laid in it at a given distance to the UAV target, disconnecting projectile bodies from the interceptor UAV to which the network is attached, deploying the network in the air, contact of the net and the UAV target in the air, according to the invention, small-sized missiles are used as propellants, the net is packed in a container, which is attached to one of the points of the net. The container is placed on an interceptor UAV. After approaching a UAV target in the air, a container with a net is dropped from an interceptor UAV, one of the ends of which is attached to an interceptor UAV. Next, missiles are launched with the ends of the network fixed on them in different directions at an angle to the direction of flight of the UAV-interceptor. An interceptor UAV performs a vertical maneuver upward relative to the missile launch directions. An interceptor UAV, missiles and a container stretch the net in the air and carry it towards the UAV target.

The combination of the listed essential features provides a technical result - an increase in the area of the network in a deployed form and the possibility of its movement in the direction of flight, maintaining the balancing of the UAV interceptor after ejection of the network, eliminating the collision of the UAV interceptor with the UAV target. This makes it possible to increase the likelihood of capture by the network of an aerial UAV target.

Brief description of figures and drawings.

The proposed method for capturing an air target with a network is illustrated by the drawings:

FIG. 1 shows a diagram of a UAV interceptor before launch. FIG. 2 shows a network deployed in the air, side view. Embodiments of the invention.

To implement the method of capturing an air target by a network, a UAV-interceptor 1 is used, shown in Fig. one.

On the UAV-interceptor 1 there is a net 2, with projectile bodies fixed at its ends, which are made in the form of small-sized missiles 3. Net 2 is laid in container 4 with the possibility of opening without entanglement when it is removed from the container 4. The ends of the net 2 are attached to the container 4 , UAV-interceptor 1 and missiles 3. Small-sized missiles 3 are located in cylindrical launchers 5 and are oriented in opposite directions at an acute angle to each other. The container 4 and cylindrical launchers 5 are fixed on the fuselage 6 of the UAV-interceptor 1. In this case, it is possible to disconnect from the fuselage 6 only the container 4, or the container 4 with cylindrical launchers 5.

The method is implemented as follows.

As shown in FIG. 2, the UAV-interceptor 1 with the network 2 laid in it approaches the specified distance to the UAV-target 7. The network 2 is pre-packed in the container 4. In this case, the network 2 at one of its points is attached to the container 4, one of the ends of the network 2 is attached to the UAV-interceptor 1, and the other two ends of the network 2 are attached to the missiles 3. The container 4 is placed on the UAV-interceptor 1.

After approaching the UAV target 7 in the air, the container 4 with the net 2 is dropped from the UAV-interceptor 1. Additionally, the missiles 3 with the ends of the net 2 fixed to them are launched from the UAV-interceptor 1 in different directions at an angle to the direction of flight of the UAV-interceptor 1, as shown in Fig. 2. An option is possible, in which the container 4 with the network 2 and the launching devices 5 of the missiles 3 rigidly connected to it are disconnected from the UAV-interceptor 1, from which the missiles 3 are then launched. Any of the options allows you to increase the area of the network 2 in the deployed form and makes it possible to move it in the direction of flight of the UAV-interceptor 1.

UAV-interceptor 1 performs a vertical maneuver upward relative to the directions of launch of missiles 3. UAV-interceptor 1, missiles 3 and container 4 stretch net 2 in the air and continue the flight with the deployed net 2 towards the UAV target 7. This allows you to keep the balance of the UAV-interceptor 1 after the ejection of the network 2, excludes its collisions with the UAV target 7 and increases the probability of capture by the network 2 of the aerial UAV - the target 7.

If there is a contact between the network 2 and the UAV target 7 in the air, the load on the UAV interceptor 1 is exceeded, the end 8 of the network 2 is disconnected from it.

If the contact between the network 2 and the UAV target 7 did not occur, then after the specified flight time of the UAV interceptor 1 after the start of the network 2, the end 8 of the network 2 is disconnected from the UAV interceptor 1. Thus, in any case, the network 2 will be detached from the UAV-interceptor 1, which will allow it to continue its flight, or to land. In addition to this, it becomes possible to drop the following containers with a network, if an interceptor UAV was equipped with them.

This allows you to obtain a technical result in the form of increasing the area of the network 2 in expanded form and the possibility of its movement in the direction of flight of missiles 3, maintaining the balancing of the UAV-interceptor 1 after the ejection of the network 2, eliminating the collision of the UAV-interceptor 1 with the UAV target 7.

This allows you to solve the problem of increasing the probability of capture of the air UAV target 7 by the network 2.

It is possible to use the invention in non-lethal anti-UAV systems for both civilian and military objects. In general, the contemplated embodiment of the invention has been implemented on existing equipment using existing materials. This confirms its performance and industrial applicability.
