Description

The invention relates to group explosion technology and can be used to increase the efficiency of hitting area targets using attack unmanned aerial vehicles.

There is a known method of firing at an area target [1], which consists in determining the aiming point for the battery guns and firing at the target, while first assessing the position and nature of the target elements, then, in accordance with the data obtained, determining the exact contour of the area target in the form of an arbitrary polygon, determining the number and position of aiming points inside the polygon, depending on its type, with the ability to ensure a uniform density of shelling of targets, the number of guns in the battery, the nature of the target, ballistic firing conditions, after which the area target is fired upon.

The disadvantage of this known method is its insufficient efficiency, since when using projectiles there is a difference in the time of their landing, which leads to their non-simultaneous detonation, and, consequently, to a reduced probability of hitting an area target. In addition, shells are detonated on the surface of the earth, and not at the optimal height, which also reduces the effectiveness of hitting the target.

The closest to the claimed invention is a method of hitting an area target with the group action of cluster munition submunitions [2] based on the detonation of submunitions delivered to an area target and placed at a given distance determined from the expression

Where:

R - distance between submunitions, m;

m - charge mass, kg,

in which they ensure the interaction of gas-dynamic flows of reacting substances and the afterburning of a mixture of active products with atmospheric oxygen, while creating an information center for monitoring the delivery of submunitions to an area target, each of which is equipped with a beacon that is triggered when the submunition interacts with an area target, after the fact of delivery is recorded by the information center for monitoring of all submunitions, a common command is formed to detonate the submunitions, while the submunitions for delivery to an area target are removed from the cluster munition at specified trajectory points, and if, after a specified time, a command is not received from the surveillance information center to detonate the submunition, it is detonated from the fuse.

The disadvantage of this known method is its lack of efficiency, since the ammunition is detonated on the surface of the earth, and not at the optimal height, which reduces the probability of hitting the target.

The technical objective of the present invention is to develop a method for hitting an area target with the group action of ammunition, eliminating the shortcomings of the prototype.

The technical result of the claimed invention is to increase the probability of hitting an area target by ensuring the simultaneous detonation of ammunition placed at a specified distance from each other at an optimal height relative to the target surface.

The technical result is achieved by the method of hitting an area target with the group action of ammunition, which is based on the detonation of ammunition delivered to the area target and placed at a given distance determined from the expression

where m is the mass of the charge, kg, R is the distance between the ammunition, m, which ensures the interaction of gas-dynamic flows of reacting substances and afterburning of the mixture of active products with atmospheric oxygen, in which, according to the invention, an information center is created for monitoring the delivery of ammunition, used as ammunition attack unmanned aerial vehicles, at the command of the information center, carry out the hovering of attack unmanned aerial vehicles over the target surface at a given distance from each other, determine in the information center the optimal hovering height of attack unmanned aerial vehicles above the target surface, carry out the movement of all attack unmanned aerial vehicles with the help of the information center devices to a previously determined optimal height, after the observation information center has recorded the fact that all attack unmanned aerial vehicles are hovering at a given distance from each other and the optimal height above the target, a common command is formed to detonate them.

New features of the invention:

- unmanned aerial vehicles are used as ammunition;

- at the command of the information center, attack unmanned aerial vehicles hover over the target surface at a specified distance from each other;

- using the information center, they move all attack unmanned aerial vehicles to a previously determined optimal height;

- after the observation information center has recorded the fact that all attack unmanned aerial vehicles are hovering at a specified distance from each other and at an optimal altitude above the target, a common command is formed to detonate them.

The above distinctive features and the known features specified in the first paragraph of the claims are essential.

A new set of essential features ensures the solution of the problem with the achievement of a technical result, namely, the probability of hitting an area target by ensuring the simultaneous detonation of ammunition placed at a given distance from each other at an optimal height relative to the target surface.

The use of a single set of essential distinctive features in known technical solutions has not been found, which characterizes the compliance of the technical solution under consideration with the “novelty” criterion.

In a particular case, the surveillance information center is placed on a manned aircraft.

In a particular case, the surveillance information center is placed on an autonomous unmanned aerial vehicle.

In a particular case, the surveillance information center is placed on a remotely piloted aircraft.

In an advantageous embodiment of the invention, the bodies of attack unmanned aerial vehicles are equipped with charge components based on explosives, rubbers and metal fuels with a total content of no more than 20% by weight.

The inventive method is the result of research and experimental work to increase the probability of hitting an area target by ensuring the simultaneous detonation of ammunition placed at a specified distance from each other at an optimal height relative to the target surface.

The drawing shows a typical implementation diagram of the method, where:

1 - observation center;

2 - attack unmanned aerial vehicle;

3 - area target;

N _opt - optimal detonation height;

R _pr - reduced distance between attack unmanned vehicles.

Example. The method is implemented as follows. Before attacking an area target 3, an information surveillance center 1 is created, which is placed on board a manned aircraft, an autonomous or remotely piloted unmanned aerial vehicle. The on-board systems of a manned aircraft, an autonomous or remotely piloted unmanned aerial vehicle, for example, a radar station, an optical-electronic system, etc., can be used as the surveillance information center 1. With the help of the surveillance information center 1, the state of the area target 3 is monitored. Then, a group of attack unmanned aerial vehicles 2 are delivered to the area target 3 area, which form a “swarm” in the target area and, at the command of the surveillance information center 1, hover over the surface of the target 3 on the given distance from each other. Then, in the surveillance information center 1, the optimal hovering height of the attack unmanned aerial vehicles 2 above the surface of the target 3 is determined, with the help of the surveillance information center 1, all attack unmanned aerial vehicles 2 are moved to a previously determined optimal height, after the observation information center 1 has recorded the fact of all the strikes hovering unmanned aerial vehicles 2 at a specified distance from each other and an optimal height above the target 3 form a common command to detonate them.

It is known [3] that detonating a weapon at an optimal height above the surface makes it possible to obtain an increase in the excess pressure of the positive compression phase of the shock wave, on average, up to 30%.

When using the on-board systems of a remotely piloted unmanned aerial vehicle as a surveillance information center 1, the command to detonate the attack unmanned aerial vehicles 2 can be given by the operator of the remotely piloted unmanned aerial vehicle.

Simultaneous detonation of attack unmanned aerial vehicles 2 at an optimal height relative to the surface of an area target 3 makes it possible to increase the likelihood of its destruction.

In one example of the invention, it is possible to equip the hulls of attack unmanned aerial vehicles with 2 charge components based on explosives, rubbers and metal fuels with a total content of no more than 20% by weight, using rubber that ensures the adhesion of the ammunition charge to the walls of the hull and the detonation speed, not exceeding 6000 m/s.

Thus, the proposed method can be used to hit an area target with the group action of ammunition. The use of the proposed method will increase the probability of hitting an area target by ensuring the simultaneous detonation of attack unmanned aerial vehicles located at a specified distance from each other at an optimal height relative to the target surface.
