Description

The invention relates to ammunition, and more specifically to tank cluster shells with fragmentation submunitions.

As a prototype of the invention adopted tank cluster shell "Likhoslavl" [1,2]. The projectile contains a housing with a head electronic trajectory-contact fuse and a screw bottom, a set of cylindrical fragmentation submunitions located inside the housing, made with a diameter equal to the internal diameter of the housing, an expelled powder charge placed between the fuse and a set of submunitions, each submunition containing an explosive charge and a fuse that provides submarine blasting after ejecting it from the hull.

The projectile provides the creation of a "chain" of gaps above the target and elongated along the trajectory of the affected area, compensating for the error of the gap coordinate relative to the target. The projectile is most effective for hitting group targets elongated along the direction of fire.

In the case when it is possible to ensure high accuracy of the gap above the target or when the group target has a configuration stretched perpendicular to the projectile trajectory, the longitudinal configuration of the lesion field becomes non-optimal. This is a disadvantage of the projectile.

The present invention seeks to remedy this drawback. The technical solution consists in the fact that the projectile is equipped with a roll stabilization device including a projectile angular position sensor and actuators, the submunitions are equipped with pulse motors, the axis of symmetry of which passes through the center of mass of the submunition perpendicular to its axis, the axis of symmetry of all engines are located in one plane passing through the axis of symmetry of the projectile and in flight parallel to the surface of the earth, pulse engines have different momentum values, with half of the submunitions firing one side of the path, and the other half - the other, are provided with fuses subsnaryadov action switch on the trajectory and impact blasting detonation delay elements at a time, the same or different for all subsnaryadov and shock vsyuduuboynogo mechanisms of action. All submunitions are connected by electric circuit to the main fuse, through which the time of transverse ejection of the submunition and the delay time of detonation after firing are introduced into the fuse of each submunition.

Figure 1 presents a longitudinal section of the projectile, figure 2 - the General layout of the sub-shell, figure 3 - section of the sub-projectile, figure 4..12 - types of action of the projectile.

The cassette shell shown in figure 1, contains a housing 1 with a screw bottom 2 and a stabilizer 3 attached to it, containing a tracer 4. A set of cylindrical sub-shells 5 is placed inside the housing. A trajectory-impact fuse 6 with a command receiver 7 is placed in the head of the housing; roll stabilization unit 8, rudders 9, powder outflow charge 10. The housing is made of high-fragmentation silicon steel 60С2 [3,4], 80Г2С [5], 80С2 [6].

Sub-shell 5 (figure 2) contains a pulse motor 11, the axis of symmetry of which passes through the center of mass of the sub-shell perpendicular to its axis. The axis of symmetry of all engines are located in the same plane passing through the axis of symmetry of the projectile and in flight parallel to the surface of the earth. An electric channel 12 with contact nodes 13 is located along the axis of the projectile. A jet engine is used as the pulse engine 11.

Figure 3 shows a submunition with a pulsed engine using ballast mass shooting. The submunition contains a housing 14 with a charge of explosive (BB) 15, a set of ready-made striking elements (GGE) 16, laid on the inner surface of the housing and made of steel or heavy alloys based on tungsten, tantalum, etc. A pulse motor is located on the section axis, containing a barrel 17, a powder charge 18, an igniter 19 and a shot ballast 20. In the rear of the barrel there is a multi-wire electric channel 12. A fuse 21 is attached to the barrel, containing a temporary device 22, an all-barrel impact mechanism 23, and detonator 24.

The projectile is multi-purpose and is designed to carry out the following types of tank shooting:

Action type Conditions, type of goal I With the ejection of submunitions and the creation of a chain of trajectory discontinuities along the trajectory A significant error in determining the range to the target. Group target stretched in direction of fire II With the ejection of submunitions and the creation of a strip of trajectory discontinuities across the trajectory Small error in determining the range. Group target stretched across a trajectory or arbitrary configuration III With the ejection of submunitions with the installation of all fuses or parts to the impact Shooting tank dangerous light armored vehicles and helicopters IV Trajectory detonation of the projectile assembly Small error in determining the range. Complex group goal or single goal V Undermining the projectile assembly when it hits the ground (setting the fuse for instant action) The failure of the tank system trajectory detonation VI Undermining the projectile assembly after penetrating through a concrete wall (setting the fuse to a delayed action) Tank-Infantry Shooting in Structures

Before the shot, the tank fire control system determines the type and configuration of the tank-dangerous target, the range to the target and produces the optimal type of action.

Setting the type of action I-VI: for types I-IV, setting flight time, for types I, II setting time intervals between submunition detonations, for type III, setting the number of sub-shells for impact action is carried out by contact or contactless input of commands through the receiver of installations on the path loading.

When installed in view II after the shot, the roll stabilization device is turned on, ensuring its flight with a continuous orientation of the plane containing the axis of symmetry of the pulse motors parallel to the ground.

Devices of this type are known and are used in real samples of tank shells, for example, in the KhM 943 STAFF shell, which, when flying over a tank, defeats its upper projection with an impact core. In the domestic patent literature, the use of such a device is provided for in the patent for the Svarog tank shell [7]

When shooting type I-III at the calculated point of the trajectory, the temporary mechanism of the head fuse 6 is triggered, the powder charge 10 is ignited and the set of submunitions is pushed back from the case with the bottom thread 2 cut.

When firing type I after the departure of the submunitions from the hull, they separate and diverge, while the orientation of the shells becomes arbitrary.

The time of detonation of the first submunition is calculated so that the submunitions flying in the group have time to disperse at distances at which the probability of damage to the fragments of the first submunition of the remaining submunitions of the group becomes negligibly small. After a predetermined period of time, the second sub-projectile and further subsequent ones are undermined. A chain of discontinuities is built along the trajectory (Fig. 4).

When firing type II immediately after the ejection of the block of submunitions from the body, the submunition fuses give orders for sequential shooting of the ballast mass, as a result of which the submunitions diverge in transverse directions to the trajectory parallel to the surface of the earth (Fig. 5). After the set intervals, the fuses give commands to detonate the submunitions, which leads to the formation of a lesion strip perpendicular to the projectile trajectory (Fig. 5)

The pattern of expansion and undermining of the submunitions for this case with the spaced apart pairwise ejection of the submunitions is shown in Fig. 7. The dotted line indicates the configuration of the group target. O is the ejection point of the first submunition, a, b, c are the trajectories of the submunitions. The estimated range U of the ejection of submunitions is determined by the ratio:

$$U=\frac{S}{2}\frac{V_C}{V_R},$$

where S is the distance between the extreme discontinuities of the submunitions;

V _C is the current velocity of the projectile;

V _R - transverse ejection velocity of the submunition.

On Fig shows a picture of the trajectories with a more complex configuration of the group target and sequential single release of submunitions.

Figure 9 shows the effect of the projectile on the group target of a complex configuration, when the radial speed is reported only part of the submunitions.

Type III is fired at large single targets, such as lightly armored platforms, anti-tank helicopters, unmanned aerial vehicles. In this case, submunition fuses are mounted on the impact. When a target is hit, a submunition explodes with local damage (Fig. 10). A combined action can be applied with the installation of part of the submunitions on the impact effect, and the rest on the trajectory detonation.

Shooting type IV (trajectory detonation of the projectile over the assembled target, 11) is carried out under the condition of accurate shooting, providing a small deviation of the break point from a compact group or single target. In this case, the head fuse generates an electrical impulse immediately to all fuses of the submunitions, which ensures their synchronous detonation in the body. In this case, a high-density circular fragmentation field is formed, which includes the GGE of the sub-shells and fragments of natural fragmentation of the sub-shell and shell shells.

Shooting of type V (undermining the projectile when it hits the ground with the fuse set to instant action) can be used when the tank system of trajectory detonation fails. It can be used when shooting at tanks based on direct hits.

Shooting of type VI (detonation of the projectile assembly after breaking through a brick or concrete wall with the fuse set to slow action, Fig. 12) is used to destroy tank dangerous infantry located in structures. Shooting can be used to destroy dugouts and bunkers.

The technical result of the invention is to increase the effectiveness of self-defense of the tank from tank infantry, including in structures from ground anti-tank equipment and anti-tank helicopters.
