Abstract

FIELD: ammunition.

SUBSTANCE: used to increase information about the effectiveness of the destructive effect of cluster bombs on ground-based complex group objects. A method for determining damage to a group object due to the damaging effect of cluster bomblets consists in detonating bomblets extracted from cluster bombs at given trajectory points, delivered to the object and placed at a certain distance from each other, creating an information center for monitoring the delivery of bomblets to the object, each of which is equipped with a beacon that is triggered when a bomblet interacts with an object. After the delivery of all bomblets is recorded by the information monitoring center, a general command is formed to detonate the bomblets. The surveillance information center additionally determines the dimensions and geometric center of the group object, after which it forms a coordinate system associated with the geometric center of the group object, and describes all vulnerable objects in its composition by rectangles with the determination of the coordinates of their geometric centers. The surveillance information center determines the coordinates of the landed bomblets, forms circular reduced zones of bomblet destruction with centers at the points of their detonation, determines the fact that the circular reduced zones of bomblet destruction cover vulnerable objects in the group object, determines the degree of damage caused by bomblets to the group object. The surveillance information center determines the amount of damage caused by projectiles to a group object, which is characterized by the degree of damage U as the ratio of the sum of damage indicators and the number of objects:

where: I_ei are indicators of the destruction of each i-th vulnerable object, and N is the number of objects, after which it transmits information about damage caused by bomblets to a dangerous object to the command control post.

EFFECT: increasing the information content of the method by determining the degree of damage caused to a ground-based complex group object by the damaging effect of cluster bomblets.

Description

The invention relates to the field of combat use of ammunition and can be used to increase information about the effectiveness of the destructive action of cluster munitions.

There is a known [1] method for determining the parameters of a group target for firing, including determining the coordinates and dimensions of the group target, describing all the elementary targets in its composition with a rectangle for aiming weapons, determining the coordinates of the elementary targets in the group, their range, directional angle and elevation angle each elementary target, determining the front and depth of the group target relative to one selected direction of the opposite cardinal points as the difference between the maximum and minimum coordinate values, determine the coordinates of the center of the group target and the average height of the group target, and the received data is transmitted by a formal message to the weapons and converted them relative to the direction of fire , in this case, the transformation of the data obtained by means of destruction is carried out in the following sequence: the directional angles from the weapon to the left and right vertices of the rectangle describing the target are determined relative to the selected direction, the absolute value of the difference in directional angles to the left and right vertices of the rectangle describing the target is determined, relative to the selected direction, determine the range to the near and far boundaries of the target relative to the weapon, as well as the front and depth of the group target for weapons, while leaving the coordinates of the center and the height of the group target unchanged, the aiming points for each gun with an automated gun guidance system are determined in in an automated mode within a truly defined target area.

The disadvantage of this method is the lack of information content, since when it is used, the degree of damage caused to a group target by the damaging effects of weapons is not assessed.

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 is the mass of the charge, kg, at which the interaction of gas-dynamic flows of reacting substances and afterburning of the mixture of active products with atmospheric oxygen is ensured, 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 surveillance information center has recorded the fact of delivery of all submunitions, a general 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 a command from the surveillance information center to detonate the submunition is not received after a specified time, it is carried out explosion from a fuse.

The disadvantage of this method is the lack of information content, since its implementation does not determine the degree of damage caused to the target (object) by the damaging effect of submunitions.

The technical objective of the present invention is to develop a method for determining the degree of damage caused to a ground-based complex group object by the damaging effect of cluster munition submunitions. In this case, a ground-based complex group object is understood as a group object consisting of a set of heterogeneous vulnerable (single) objects interconnected by the unity of functioning when performing a common task, and containing objects that decisively influence the functioning of the entire object (for example, anti-aircraft missile system, etc.) [3].

The technical result of the invention is to increase the information content of the method by determining the degree of damage caused to a ground-based complex group object by the damaging effect of cluster munition submunitions.

The technical result is achieved by using a method for determining damage to a ground-based complex group object by the destructive effect of cluster munition submunitions, which consists in detonating submunitions extracted from cluster munitions at given trajectory points, delivered to the object and placed at some distance from each other, creating an information center for monitoring the delivery to submunition object, each of which is equipped with a beacon that is triggered when the submunition interacts with the object, after the surveillance information center has recorded the fact of delivery of all submunitions to the object, a general command is formed to detonate the submunitions, while the surveillance information center additionally determines the dimensions and geometric center of the complex group object, forms a coordinate system associated with the geometric center of a group object, describes all vulnerable objects in its composition by rectangles with determination of the coordinates of their geometric centers, determines the coordinates of landed submunitions, forms circular reduced zones of destruction of submunitions with centers at the points of their detonation, determines the fact of coverage by circular reduced zones of destruction submunitions of vulnerable objects as part of a complex group object, determines the amount of damage caused by submunitions to a complex group object, transmits information about the damage caused to a complex group object to the command control post.

New essential features of the invention:

- the surveillance information center additionally determines the dimensions and geometric center of a complex group object, forms a coordinate system associated with the geometric center of the group object, describes all vulnerable objects in its composition by rectangles with the determination of the coordinates of their geometric centers;

- forms circular reduced zones of destruction of submunitions with centers at the points of their detonation, determines the fact of coverage of vulnerable objects as part of a complex group object by circular reduced zones of destruction of submunitions;

- the surveillance information center determines the amount of damage caused by submunitions to a complex group object;

- the surveillance information center transmits information about the damage caused to a complex group object to the command control post.

A new set of essential features in combination with known ones provides a solution to the problem with the achievement of a technical result, which consists in increasing the information content of the method by determining the degree of damage caused to a ground-based complex group object by the damaging effect of cluster munition submunitions.

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.

The above set of new essential features in combination with common known ones ensures the solution of the problem with the achievement of the required technical result and characterizes the proposed technical solution with significant differences compared to the known level of technology.

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.

The inventive method is the result of research and experimental work to increase the information content of the method by determining the degree of damage caused to a complex group object by the damaging effect of cluster munition submunitions.

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

1 - complex group object;

2 - 8 - vulnerable (single) objects of a ground-based complex group object;

9 - circular reduced zone of destruction of the submunition;

10 - surveillance information center.

R _P - radius of the reduced zone of destruction of the submunition;

- a vector that determines the position of the submunition and its circular destruction zone relative to the center of the target;

- vector characterizing the position of an elementary object relative to the geometric center of a complex group object;

- a vector characterizing the position of the submunition and its circular destruction zone relative to the elementary object.

Example. The method is implemented as follows. Before an attack on a ground-based complex group object, an information surveillance center 10 is created, which is placed on board an autonomous or remotely piloted unmanned aerial vehicle.

The onboard systems of 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 10.

With the help of the surveillance information center 10, a ground-based complex group object 1 is detected and recognized. Then, a set of cluster warheads of multiple launch rocket system projectiles or cluster aircraft munitions are delivered to the area of the complex group object 1, which in a given area form a “swarm” of submunitions covering the complex group object 1. Each of the submunitions is equipped with a beacon (for example, a radio beacon), which begins to operate after the submunition lands.

The presence of beacons on the submunitions makes it possible to inform the surveillance information center 10 about the fact and coordinates of their landing. Also, at the moment of landing, the submunition fuses are switched into firing position.

The fact of landing and the coordinates of all submunitions is recorded by the surveillance information center 10. Before the landing of the last submunition, the surveillance information center 10 determines the dimensions and geometric center of the ground-based complex group object 1, forms a coordinate system associated with the geometric center of object 1, describes all vulnerable objects in its composition with rectangles with determining the coordinates of their geometric centers. After the landing of the last submunition, the observation information center 10 determines the coordinates of the landed submunitions, forms circular reduced zones of destruction of 9 submunitions with centers at the points of their detonation, generates a command to detonate them, determines the fact of covering vulnerable objects 2-8 within the object with circular reduced zones of destruction of 9 submunitions 1, determines the degree of damage caused by submunitions to object 1, transmits information about the damage caused to object 1 to the command control post.

Determining the degree of damage caused by submunitions to a ground-based complex group object 1 is carried out as follows. For each of the submunitions that hit object 1, a circular destruction zone is determined with a radius determined by the formula , where S is the reduced zone of destruction of the submunition. The value of S is determined from manuals on the combat use of aviation, missile forces and artillery [4]. Object 1 usually consists of N vulnerable objects, which are functional subsystems (nodes, assemblies) of the original object. The position of each elementary object relative to the geometric center of object 1 is specified by the vector , i=1,N. The position of each submunition and its circular destruction zone relative to the center of object 1 is characterized by a radius vector . Then the position of the submunition relative to the i-th vulnerable object is characterized by the radius vector .

Next, in the information center 10, indicators of the defeat of each i-th vulnerable object 1 are determined. These indicators are determined by the following ratio:

where R _P is the radius of the circular zone of destruction of the submunition.

By summing up the damage indicators for all vulnerable objects of object 1, one can assess the degree of damage caused to the object by submunitions.

In accordance with accepted standards for the use of aviation and rocket-artillery ammunition, a group target is considered hit when U≥0.5 [4].

Next, information about the degree of damage U caused by submunitions to object 1 is transmitted from the surveillance information center 10 to the command control post.

If a command from the surveillance information center 10 to detonate submunitions is not received after a specified time, they are detonated using standard fuses.

When using 10 onboard systems of a remotely piloted unmanned aerial vehicle as a surveillance information center, a general command to detonate submunitions can be given by the operator of the remotely piloted unmanned aerial vehicle.

Thus, the proposed method can be used in assessing the degree of damage to a ground-based complex group object due to the group action of cluster munition submunitions. The use of the proposed method will improve the information content of the method by determining the degree of damage caused to a complex group object by the damaging effect of cluster munition submunitions.
