Description

The invention relates to the field of aviation technology, in particular to unmanned aerial vehicles (UAVs) and is intended to combat various types of aircraft and destroy ground-based radio-electronic systems using electromagnetic pulses (EMP).

The main technical means of obtaining powerful electromagnetic pulses, which form the basis of low-frequency electromagnetic weapons (EMW), is a generator with explosive compression of the magnetic field. Another potential type of high level low frequency magnetic energy source could be an electromagnetic pulse generator powered by propellant or explosive. The combat charge delivers equipment to the affected area, which becomes a source of destructive radiation for semiconductors, transistors, circuit boards and microcircuits. The most vulnerable to EMP are active phased antenna arrays, which are part of the electronic stations (radar) of modern combat aircraft and ships, ground-based air defense systems, radio communications, aircraft control systems, UAVs, missiles, etc.

One of the pioneers in the field of electromagnetic weapons is Academician Andrei Sakharov, who, back in the 1950s, proposed the concept of a non-nuclear bomb with EMP. Research and development research in this area started in the USSR and Western countries in the 1960s.

Currently, developments in this area have reached a new level, in the field of practical application. The US had previously used an EMP guided bomb in 1999 against Serbia. The bomb was guided, the probable deviation of the irradiation directrix from the aiming point was less than ten meters. The radius of destruction of this electromagnetic bomb did not exceed 200 m. The result of its action was to turn off television broadcasting for several hours. In 2003, the United States repeatedly used such bombs against Baghdad and other cities in Iraq, the power of such bombs was much greater. In a press release dated 07/21/2021, the American military-industrial company Raytheon, which is directly involved in the development of drones, announced the result of a non-kinetic test of the Coyote Block 3 system. They managed to successfully hit 10 drones that differed in “size and complexity, maneuverability and range.” Also, a number of significant successes have been achieved in the field of hitting targets with non-kinetic air-to-air weapons, demonstrating the survivability, recovery and reuse of the drone during the same test event.

It is known that work on the subject of EMO is also being carried out in our country. A few years ago, information appeared in the domestic press about the development of a promising missile system with a warhead in the form of an electromagnetic warhead. This product became known under the name "Alabuga". A number of other developments on this topic are also known. Some of them are reflected in the database of the Federal Institute of Industrial Property.

A known method of combating short-range and short-range unmanned aerial vehicles (RU 2551821 dated December 30, 2013), which consists in detecting an unmanned aerial vehicle, determining the distance to it, orienting a radiating antenna in its direction, calculating the radiation power and generating electromagnetic radiation, characterized in that the wavelengths of electromagnetic radiation are selected in the range of 10-20 cm, while by changing the power of generation of electromagnetic radiation, the radiation power of the antenna is set, which ensures the induction of currents on parasitic antennas of the unmanned aerial vehicle, sufficient to disable the onboard control system.

The disadvantage of this method is the complexity of the constructive implementation, which combines the need to ensure the accuracy of detection and ranging to the UAV and the accuracy of pointing the radiating antenna at it, as well as the need to use energy-intensive energy sources.

Also known is an explosive generator of electromagnetic pulses (RU 2709255 dated 12/17/2019), including a metal case made of structural material, the main charge of a high explosive and a detonation initiation system, including explosive elements - initiating devices, additional transmission and / or amplifying detonators and a set auxiliary devices and devices that ensure the activation of explosive elements of initiating devices, the body is made of two identical parts or box-shaped, having an open shape and representing two parallel plates with edges bent towards each other, or having the shape of hemispheres or semi-ellipsoids, directed by open cavities towards each other to each other, subject to the condition of absence of contact between them, made of thin, up to 0.5 mm thick, sheet of aluminum or aluminum-magnesium alloy, fastened together by at least one tightening device made of thin electric electrically insulating material in the form of electrical tape or adhesive tape of the "Scotch" type, while the main charge is either cast or pressed checkers of individual or mixed explosives, or charges of plastic or elastic explosives, repeating in shape the internal cavities of the hull parts folded together, taking into account a guaranteed gap between these parts, and the initiation system is made double-sided, where the same type of explosive elements and the same type of detonators are placed towards each other on the axis of the device in the gaps between the body parts. In the middle part of the main charge, at an equal distance from the additional detonators and/or explosive elements - initiating devices, there is a checker made of a plasma-forming composition containing ultrafine aluminum.

The disadvantage of this device is the non-selectivity of the effect of EMP on electronic equipment, which imposes certain restrictions on the use, in order to achieve the greatest effect of destruction, it is necessary to increase the power of the generated pulses, which directly affects the mass of the plates and the mass of the explosive and is reflected in the weight and size characteristics of the device or requires maximum approximation to the object of destruction.

The closest in technical essence to the claimed invention is a method of functional suppression of unmanned aerial vehicles (RU 2700206 dated September 13, 2019), which consists in detecting an unmanned aerial vehicle, delivering it to an area at a distance of 50-100 meters, from an unmanned aerial vehicle using a launcher cartridge device containing a warhead, a power source, a self-destruction charge through a tracer designed to self-destruct the device with the simultaneous creation of a cloud of damaging elements, an “electromagnetic charge” with elements that provide functional suppression of an unmanned aerial vehicle, as well as a generator of ultrashort microwave radio pulses that generates a series of ultrashort microwave radio pulses in the frequency range of 0.5-10 GHz towards the unmanned aerial vehicle until the power source is completely discharged, the production of a self-destruction charge is detonated at a distance standing 50 - 80 meters from the affected unmanned aerial vehicle, as a result of which a field of striking elements is formed, which leads to physical damage and destruction of the unmanned aerial vehicle.

The disadvantage of this method is the complexity of the constructive implementation, the need for significant energy costs for the implementation of suppression, the redundancy of the use of several different methods of defeating the UAV.

The objective of the invention is to create an unmanned system capable of deploying at high altitude in a short period of time, staying in the air for a long time, having the ability to detect, approach and hit enemy air and ground targets, which include electronic equipment consisting of semiconductors, circuit boards and microchips.

The required technical result is achieved by the fact that the unmanned aerial vehicle for destroying enemy radio-electronic means consists of a carrier unmanned aerial vehicle and a combat charge separated from it. The body of an unmanned aerial vehicle of a cylindrical shape, with rudders retracted inside the body, surveillance equipment and folding wings, is placed in a transport and launch container.

The combat charge is a detachable rocket projectile with an explosive generator of electromagnetic pulses and a remote detonation system.

The body of the unmanned aerial vehicle has retractable horizontal and vertical rudders in the front of the body, a retractable surveillance system in the upper and lower hemispheres, which is an optical and infrared camera, folding wings in the middle part of the body, a solar battery is applied to the wings and the upper part of the body, inside housings are located: a control system, a communication system, a GLONASS satellite navigation system unit, a storage battery, a parachute system, an electric motor with a screw pusher propulsion unit with folding blades. To the rear of the body is a solid propellant booster, detachable block.

The essence of the invention is illustrated by drawings, where in Fig. 1 and FIG. 2 shows diagrams of an unmanned aerial vehicle for destroying enemy electronic equipment, which contain:

1 - combat charge;

2 - cone-shaped front part of the body;

3 - surveillance system;

4 - folding wings;

5 - parachute system;

6 - solid propellant accelerating, separable block;

7 - screw pusher propeller with folding blades;

8 - body;

9 - horizontal and vertical rudders.

On FIG. 3 shows a diagram of a combat charge:

10 - remote detonation system;

11 - explosive generator of electromagnetic pulses;

12 - jet engine;

13 - lattice.

The invention works as follows: an unmanned aerial vehicle for destroying enemy electronic equipment in the assembled state, in a transport and launch container is transported to the area where the enemy is supposed to use the UAV or deploy electronic equipment. When a danger of use or detection by means of surveillance of an enemy UAV is detected, the device is launched. The launch is made from the transport and launch container in the direction of the possible location of targets. Due to the solid-propellant booster detachable unit (6), the unmanned aerial vehicle is brought to a maximum altitude exceeding the flight altitude of the main types of UAVs used, the use of which is possible in this area. After separating the solid propellant booster, separable block (6), the unmanned aerial vehicle goes into horizontal flight. At the command of the control system, folding wings (4) folded around the body (8), made of flexible plastic and fixed by a fastening device, are opened, horizontal and vertical rudders (9) are also extended to control the flight. At the same time, cameras of the optical and infrared range of the surveillance system (3) are extended to view the upper and lower hemispheres. After disconnection of the solid propellant accelerating, separable block (6), the screw pusher propeller with folding blades (7) is released and put into operation, until that moment being in the folded state in a special space of the upper part of the solid propellant accelerating detachable block (6). An unmanned aerial vehicle for destroying air and ground targets carries out flight due to an electric motor located in the housing (8), receiving power from a battery and a solar battery, like all other consumers. Flight control is carried out from the control point via radio channels through the control system, using horizontal and vertical rudders (9) for maneuvering, located in the front of the body (8) for effective flight control. Due to the large area of the solar battery, which allows replenishing electricity reserves in flight, and the presence of a high-capacity battery, an unmanned aerial vehicle for destroying enemy electronic equipment is able to barrage in the area for a long time, transmitting the state of the air, ground (sea) situation to the control point.

Upon detection of an object of destruction, at the command from the control center, an unmanned aerial vehicle to destroy enemy electronic equipment at the maximum possible speed starts approaching, using, among other things, the rate of descent. Upon reaching the distance of defeat on command from the command post, a combat charge (1) is launched. The jet of a jet engine (12) flows around the cone-shaped front part of the body (2), flowing through the grate (13) is separated from the body (8). When approaching an object at a distance of destruction, using a remote detonation system (10), an explosive generator of electromagnetic pulses (11) is detonated, generating high-power EMP, leading to the destruction of the element base of electronic equipment and, as an additional effect, defeating the enemy with the components of an explosive generator of electromagnetic impulses ( eleven).

The use of such a warhead (1) will be effective for disabling both a single and a swarm of UAVs, enemy aircraft and missiles, and ground-based electronic equipment. The maximum effectiveness of the destruction is achieved by delivering the combat charge (1) close to the enemy's assets, which also ensures safety for their electronic assets.

After launching the combat charge (1), the unmanned aerial vehicle for destroying the enemy's electronic equipment makes a flight to the base and lands using a parachute system (5). It can be used repeatedly by re-equipping with a live charge (1) and performing pre-flight preparation.

An unmanned aerial vehicle for destroying enemy radio-electronic means is a universal means for destroying both mobile and stationary objects. Allows you to hit electronic equipment with high noise immunity, using special devices for protection against energy overloads, operating in a passive mode. Its use will help prevent damage to protected objects from being hit by air attack weapons, even with their massive use.
