Description

The invention relates to cluster munitions, and more particularly to cluster munitions with axial flows of ready-to-use striking elements (GGE).

The projectile "P" [1] contains two throwing units with expelling powder charges. The block consists of a body with an explosive charge and a single-layer set of GGE at the end and a fuse with a moderator. When the projectile approaches the target, the blocks are expelled by successive charges from the hull, and then they are undermined and thrown by the GGE. The disadvantage of this design is the non-optimal configuration of the throwing blocks (their relatively high height), which leads to a low utilization of explosive charge energy and a small number of blocks.

This disadvantage is eliminated in the design [2], in which the throwing unit is made in the form of a low cylinder. Blasting blocks through the nodes of the slowdown. The dispersion of the response time of the moderators is quite large, which can lead to the destruction of propellant blocks by fragments and GGE of previously triggered blocks. The design lacks a mechanism for breeding blocks, which can lead to overlapping axial flows of individual blocks.

The present invention addresses these drawbacks. The technical solution consists in the fact that the cluster shell with fragmentation-beam blocks contains a housing with a head trajectory fuse with a shock mechanism of contact action and a detonation channel, a bottom expelling powder charge and a set of cylindrical throwing blocks located in series along the axis of the shell and consisting of the case of the block, the explosive charge located therein and the fragmentation disk located on the front end of the explosive charge and the fuse block. The projectile is equipped with a bottom fuse, a device for breeding throwing blocks in radial directions and a synchronous blasting system for blocks.

It is the specified combination of features that eliminated the disadvantages of the prototype.

In private embodiments of the invention, the bottom fuse is equipped with an inertial mechanism.

The head trajectory fuse is made of a temporary, non-contact or command type.

The head traction fuse is equipped with a pyrotechnic device for separating from the body.

The throwing unit is made with a device for shooting ballast weight in the radial direction, while the axis of the ballast weight is made passing through the center of mass of the throwing unit.

The angles between the axes of the ballast weights are 360 ° / n, where n is the number of blocks.

The unit is equipped with a retractable rod, which is under the action of a preloaded spring and connected to the fuse trigger.

The head fuse is equipped with an emitter of optical or radio frequency signals mounted on the bottom surface of the fuse and provided with a deceleration element, and the missile unit is equipped with a radiation receiver connected via an electronic circuit to the detonator of the missile unit.

The invention is illustrated by drawings.

In Fig.1 shows a cluster fragmentation-beam projectile for a smoothbore tank gun, Fig.2 is a longitudinal section of a propelling unit, Fig.3 is a cross section of a propelling unit, Fig.4 is a rotation transmission device, Fig.5 is a propelling block with a layer of GGE, Fig.6 is a diagram of the action of the projectile.

The cassette shell shown in figure 1, includes a housing 1 containing a bottom fuse 2 with an inertial shock mechanism, a knockout powder charge 3, a set of throwing blocks 4, a head fuse 5 trajectory action (temporary, non-contact or command) with a fuse separation mechanism 6, the emitter of the actuation signals 7, the receiver settings 8, the head contact node 9, the detonation channel 10. Stabilization of the projectile in flight is provided by a drop-down stabilizer, while the stabilizer blades are made with a small angle of attack, which ensures twisting of the projectile and gyroscopic stability of flight of the blocks after ejecting them from the shell of the projectile.

The throwing block (figure 2, 3) contains a housing 11 with a charge of explosive 12 placed in it. The housing is integral with the hollow axial strut 13 and radial tubes 14. At the front end of the throwing block a fragmentation disk 15 of predetermined crushing with a central hole 16 is located. an optical axis 17, a fuse of a propellant block 18 of a safety type with a pyrotechnic channel 19, a detonation channel 20, a detonator 21 and transfer charges 22. is placed in the hollow axial strut 13. An expelling powder charge 23 and b is placed in the upper (in FIG. 2) allast weight 24. The axis of the ballast weight passes through the center of mass of the propelling unit. In the lower (in figure 2) radial tube there is a movable rod 25 with a preloaded spring 26 connected to the trigger of the fuse.

The transmission of torque from one throwing unit to another and from the shell of the projectile to a set of throwing blocks is implemented using a mechanical device, for example, presented in figure 4 (27). Figure 5 shows the design of the throwing unit with a fragmentation disk made in the form of a single-layer set of GGE (28). The blocks are laid in the housing in such a way that the angle between the axes of the ballast weights placed in the radial tubes 14 is 360 ° / n (n is the number of blocks).

The projectile is multi-program, i.e. depending on the installation introduced, it can carry out a trajectory action (with a gap in front of the target and its defeat by the total stream of GGE of throwing blocks and a gap over the target of the projectile assembled with the target hitting the target with a circular field of fragments of the shell and blocks) or impact action. Setting the type of action is introduced before firing through the receiver settings 8.

When installed on the axial action of the GGE flow, which is the main type of projectile action, the fuse is triggered at the calculated point of the trajectory and is separated from the body. The shock acting on the shell is perceived by the inertial mechanism of the bottom fuse, as a result of which the expelling powder charge 3 is ignited and the blocks are ejected from the shell. When the unit exits the front end of the housing, the movable rod 25 is pushed out of the housing of the unit under the action of a spring, turns on the electronic circuit of the fuse, removes the protection stage, at the same time the outburst charge 23 is ignited and the ballast load is shot 24. Under the action of the pulses, the blocks diverge in radial directions, freeing up space for throwing fragmentation discs. At the calculated moment of achieving the necessary dilution of the blocks, which corresponds to the absence of overlapping projections of the blocks of each other, the radiation source is activated, located on the bottom surface of the fuse. Infrared radiation is considered as the main type of signal, however, a radio signal, including a microwave signal, can also be used. The signal is perceived by the receiver 17, amplified by an electronic circuit and fed to the detonators of the throwing units. There is a synchronous undermining of all blocks with the formation of a directed axial flow ("beam") of GGE. Signaling with fiber optics is not ruled out. When using the method of command detonation from an external console, a command is first issued to separate the warhead, and after exiting and breeding throwing blocks, a command is given to detonate them.

In the case of firing at the impact, the percussion mechanism of the head fuse through the detonation channel causes detonation of the explosive charge of the front block with the transfer of detonation to the entire set of blocks. Similarly, the projectile operates with a trajectory rupture carried out without throwing throwing blocks. In these cases, targets are defeated due to the compression action of the projectile (the action of an air shock wave) and fragments flying from the side surface of the throwing blocks, as well as fragments of the natural fragmentation of the body. GGE sets with this type of action have a relatively small radial velocity, but, nevertheless, make a significant contribution to the overall fragmentation effect of the munition.

The advantages of the proposed projectile are most pronounced for shells that have a flat trajectory, since they provide a large depth of damage. One of the most promising applications for shells of this scheme are shells for tank guns, designed to suppress tank-dangerous ground and air targets. This projectile can be successfully used in the ammunition of a 125 mm smoothbore tank gun 2A46M-2 of the T-90S main tank, equipped with the Aynet remote-blasting system [3]. A 3VM18 electronic remote-contact fuse with a 52 mm spectacle thread has been developed for this system [4]. The characteristics of one of the design options for a 125 mm cassette fragmentation beam projectile are: the mass of the projectile (corresponding to the mass of a regular high-explosive fragmentation projectile 3OF19) - 23.2 kg, the number of throwing units - 5, the weight of the throwing unit - 2.8 kg, the mass of the explosive charge throwing unit - 0.54 kg, the mass of the fragmentation disk of a given crushing (ZD) - 0.6 kg, the number of fragments of the ZD in one plate - 120, the mass of one fragment of the ZD - 5 g, the total number of fragments in the axial flow - 600, the initial speed fragments relative to the block (calculated) - 1020 m / s, p The total initial velocity of the fragments at a projectile speed of 700 m / s is 1720 m / s, the probability of hitting the target (calculation of ATGMs at a distance of 2000 m) is 0.95.

Cluster fragmentation-beam projectile is very promising for light helicopter transportable assault guns of mobile forces. According to the tactical conditions of regional conflicts, fragmentation-compression shells with an increased explosive charge and axial-action shells with a large depth of destruction are necessary for these systems. Due to the fact that the initial velocity of the assault cannon shells is small (250-300 m / s), the possibility of using conventional powder shrapnel and card shells disappears, and the most promising is the fragmentation-beam projectile of a single-block or cluster type. Calculations show that when suppressing small maneuvering groups of the enemy in the conditions of persistent firing, a cluster fragmentation-fragmentation shell has a significant advantage over other types of shells, including monoblock fragmentation-fragmentation shells according to patents
