Description

The invention relates to means of combating unmanned aerial vehicles (UAVs), primarily, small-sized UAVs and guided aerial bombs (UAB), which have small body dimensions, but have aerodynamic surfaces.

Known traditional means of destruction of small-sized air targets, which, with the help of fragmentation striking elements, directed at the target mainly in the direction of flight of the projectile when it is detonated, do not have such a significant damaging effect on the target due to the small effective projection area of the air target and the design features of its aerodynamic surfaces , as a rule, made of easily pierced plastic, the penetration of which does not significantly affect the flight characteristics of an air target. To increase the effectiveness of destruction of small targets in the projectile, the explosive charge is increased, the mass of the damaging elements is increased, which leads to an increase in the mass of the projectile and the need to use artillery barrels. Thus, the possibility of using such projectiles with unmanned aerial vehicles used to destroy small-sized air targets is practically excluded due to the significant mass, dimensions and high recoil when firing, the relatively low density of the damaging elements, in addition, due to the high lethality of this kind of projectiles it is difficult to use them in peacetime.

Known fragmentation ammunition having both axial and circular damage fields [RF patent No. 2247929, IPC F42B 12/56, publ. 03/10/2005], including a body with a set of projectile blocks sequentially located along the projectile axis, each of which contains an explosive charge and a set of ready-made striking elements placed on its end surface facing the projectile head. The projectile is made with the possibility of pushing the blocks apart without separating them from the projectile, for which it is equipped with a hollow axial beam, the projectile blocks are made with an axial channel having a section corresponding to the section of the beam. Before blasting, the blocks are moved apart along the beam. Layers of ready-made striking elements are laid on the front ends of the blocks. When the blocks are detonated, the total axial flow of the damaging elements is formed, and at the same time, in accordance with the principle of the active mass of the explosive charge (HE), K.P. Stanyukovich ensures the most complete use of the energy of explosive charges when ejecting blocks.

The disadvantages of the analog are:

- the need to use a significant amount of explosives to achieve the required velocity of the damaging elements;

- insufficient flux density of damaging elements in the case of counteracting small-sized targets, for example, UAVs;

- low efficiency of destruction of UAVs by fragments penetrating the aerodynamic surfaces of UAVs, but not destroying them.

Known fragmentation-beam projectile "POSVIZD" [RF patent No. 2368864, IPC F42B 12/20, F42B 12/58, publ. 09/27/2009 bul. No. 27], containing a body with a set of projectile blocks sequentially located along the projectile axis, motionlessly fixed in the projectile body, each of the propelling blocks contains an explosive charge and ready-made striking elements.

In this device for creating a projectile with a guaranteed provision of axial fragmentation action and hitting the target with an axial flow of ready-made striking elements, the striking elements are laid on the end surface of the explosive charge facing the projectile head, and the distance between the projectile blocks exceeds 0.8 of the throwing block diameter. This device is taken as a prototype.

The disadvantage of the prototype is the relatively low probability of defeat / capture of small UAVs or UAVs, namely:

- insufficient flux density of damaging elements in the case of counteracting small-sized targets, for example, UAVs;

- low efficiency of destruction of UAVs by fragments penetrating the aerodynamic surfaces of UAVs, but not destroying them;

- the need to use a significant amount of explosives to achieve the required velocity of the damaging elements;

- the impossibility of using in peacetime or for non-lethal defeat, incl. target acquisition.

The objective of the claimed invention is to create a projectile for dealing with small-sized UAVs or UABs with an increased likelihood of their destruction or capture.

The technical result to be achieved by the claimed invention is to increase the likelihood of defeat / capture of small UAVs or UABs by increasing the area of effective damage.

The technical result is achieved in that a projectile for combating unmanned aerial vehicles (UAVs), containing a body with a set of projectile blocks sequentially located along the projectile axis, fixed in the projectile body, each of the propelling blocks contains an explosive charge and ready-made striking elements, according to the invention the explosive charge in each propellant block is placed in an explosion chamber, which has gas outlet channels located around the circumference and oriented normally to the direction of flight of the projectile, in which the striking elements are placed, which are weights connected by flexible connecting cutting elements, laid in a folded state on the side the surfaces of the projectiles, the projectiles being rotated relative to each other in azimuth around the projectile axis, and the projectile bottom igniter and the blasting chambers are interconnected by explosive delay lines in the form of a garland.

Placement of explosive charges in each propelling unit into an explosion chamber, which has gas outlet channels located around the circumference and oriented normally to the direction of flight of the projectile, into which the striking elements are placed, which are weights connected by flexible connecting cutting elements, laid in a folded state on the side surface of projectile blocks, allows you to shoot loads normally to the direction of flight of the projectile and unfold a "web" of connecting cutting bodies, thereby increasing the area of effective damage to small UAVs or UABs: either damaging or cutting the aerodynamic surfaces of an airborne object, or catching on it and interfering in the mode capture normal flight. This kind of impact on an air target significantly reduces the requirements for the used mass of explosive in the projectile, because is equivalent to the release of a trapping net, thereby significantly reducing the lethality of the impact of the projectile.

The turn of the throwing blocks relative to each other in azimuth around the axis of the projectile increases the number of unfolded connecting bodies, thereby increasing the area of destruction of the UAV.

The connection between the bottom fuse of the projectile and the explosion chambers by explosive delay lines in the form of a garland makes it possible to synchronously turn the connecting bodies, thereby increasing the area of destruction of the UAV.

In addition, for the technological simplification of the connection of weights and the elimination of the effect of their emissions on the axial stability of the projectile flight, flexible connecting cutting elements of different weights are laid through the center of the throwing unit.

In addition, to simplify the assembly technology of the projectile, the flexible connecting cutting elements can be rolled up on the weights.

In addition, a metal wire or rope, or a braided synthetic thread can be used as flexible connecting cutting elements.

Thus, the combination of all the above signs creates conditions for increasing the likelihood of hitting / capturing small unmanned aerial vehicles or guided aerial bombs.

The presence in the claimed invention of features that distinguish it from the prototype makes it possible to consider it as corresponding to the "novelty" condition.

New features, which contain the distinctive part of the claims, have not been identified in technical solutions for a similar purpose. On this basis, it can be concluded that the claimed invention meets the condition "inventive step".

The invention is illustrated by drawings, where:

in fig. 1 shows a cross-section of a projectile for combating unmanned aerial vehicles;

in fig. 2 shows a projectile with two throwing blocks deployed at 45 ° in azimuth relative to each other, in a state with deployed flexible connecting cutting elements connected to the projectile weights;

in fig. 3 shows a variant of laying flexible connecting cutting elements on weights.

The device is made as follows.

A projectile for combating unmanned aerial vehicles (UAVs) (Fig. 1) contains a body formed by a set of projectile blocks 1 arranged in series along the projectile axis, fixed in the projectile body, each of which contains an explosion chamber with an explosive charge 2. To the explosive chambers 2 adjoin gas ducts 3 located around the circumference and oriented normally (radially) to the direction of flight of the projectile. The fired weights 4 are inserted into the gas outlet channels 3, connected to flexible connecting cutting elements 5, laid (rolled) in the cavity 6 on the side surface of the throwing blocks 1. The laid flexible connecting cutting elements 5 and the ends of the fired weights 4 can be protected by the firing plugs 7. Bottom projectile igniter 8 (or propellant propellant charge) and explosive chambers 2 are interconnected by explosive delay lines 9 in the form of a garland. To technologically simplify the connection of weights and eliminate the effect of their emissions on the axial stability of the projectile flight, flexible connecting cutting elements 5 of two different projectile weights 4 can be single and run in a groove (not shown) through the center of the corresponding projectile unit 1. In addition, to simplify the assembly technology of the projectile, the flexible elements 5 can be in a folded state on the weights themselves 4. The flexible connecting cutting elements 5 can be used: a metal wire or cable, or a braided synthetic thread. In order to increase the affected area, the throwing blocks 1 are rotated relative to each other in azimuth around the projectile axis. For example, in FIG. 2 shows a projectile with two projectiles deployed at 45 degrees in azimuth relative to each other, in a state with deployed flexible connecting cutting elements 5 connected to the projectile weights 4. FIG. 3 shows a variant of laying flexible connecting cutting elements 5 on the free ends of the fired loads 4. The projectile works as follows.

When the projectile is flying (fired) towards a small-sized UAV or UAB at the initially set time, the bottom igniter 8 of the projectile is triggered, which ignites the first of the explosive delay lines 9 connected to it, from which the explosive charge is triggered in the blast chamber 2 of the nearest of the propelling blocks 1. From the gas outlet ducts 3 adjacent to the blast chamber 2, the projected weights 4 inserted into them fly out, connected to flexible connecting cutting elements 5, laid (rolled) in the cavity 6 on the side surface of this propelling unit 1. The weights 4 are ejected normally (radially) to the direction of flight the projectile and pull (unfold) the flexible connecting cutting elements 5, thereby forming a cutting network. The detonation of the explosive charge in the explosive chamber 2 of the first propelling unit 1 ignites the explosive delay line 9 connected to it, leading to the explosive chamber 2 of the next (second) propelling unit 1, in which a similar process of detonation of the explosive charge and the flight of the fired loads 4 take place and pulling the flexible connecting cutting elements 5 from the second throwing block 1. In the same way, the subsequent ignition of the explosive charge and the ejection of the projected weights 4 and pulling the flexible connecting cutting elements 5 from the subsequent throwing blocks occurs. Throwing blocks can be rotated relative to each other in azimuth, increasing the number of beams in the deployed network and increasing the likelihood and effectiveness of hitting or capturing small UAVs or UABs.

Currently, the development of documentation on the results of experimental modeling of projectiles is underway, production and preliminary tests of the device made in accordance with the claimed invention are planned.

The presented information testifies to the fulfillment of the following set of conditions when using the claimed invention:

- the claimed device refers to the means of combating unmanned aerial vehicles (UAVs), first of all, small-sized UAVs or guided aerial bombs (UAB), which have small body dimensions, but have aerodynamic surfaces;

- for the claimed device in the form in which it is described in the claims, the possibility of its implementation is confirmed using the means and methods described in the application and known before the priority date.
