Description

The invention relates to ammunition with targeted fragmentation fields (see, for example, V.A. Odintsov. Design of fragmentation ammunition. Part 1, study guide, publishing house of MSTU named after N.E.Bauman, 2002. p. 32-35).

Known fragmentation-beam projectile, selected for the closest analogue, containing a shock-time fuse, directed fragmentation warhead, consisting of throwing units sequentially located along the axis of the projectile, each of which contains a body with a charge of explosive and a fragmentation plate, bottom expelling powder charge , ground fuse, a device for breeding throwing blocks in radial directions and a synchronous blasting system of blocks (RU 2237233, publ. 2004) The disadvantage of this projectile is the presence in lifting charge for discharging propellant blocks and simultaneous detonation systems, which complicates its design, as well as low density striking field caused by the expansion of submunitions.

The present invention is aimed at improving the effectiveness of the damaging effect, by giving the PE beam a rational shape and optimal focus when flying towards the target.

The problem is solved in that the projectile contains a shock-time fuse and a directional fragmentation warhead consisting of throwing blocks, each of which contains a body with an explosive charge and a fragmentation plate. The projectile is equipped with an axial load-bearing beam, and the throwing blocks are parallelepiped-shaped and made of two types, while the throwing blocks of the first type are located on the axial load-bearing beam at certain distances from each other, and the throwing blocks of the second type are laid on the axial load-bearing beam and are hinged to the ribs throwing blocks of the first type with the possibility of their disclosure and fixation in the open position using mechanical or pyrotechnic systems.

In particular embodiments, recesses can be made on the rear sides of the throwing blocks of the second type to fit them tightly onto the axial load-bearing beam. The fragmentation plate can be made in the form of a single-layer or multi-layer set of ready-made striking elements (GGE) or in the form of a plate of a given crushing, or in the form of a plate with spherical depressions extruded on it, facing the vertices to the explosive charge. GGE can be made of steel or heavy alloys based on tungsten in a form that ensures their tight packing in a set. The axial carrier beam can be hollow and it contains a set of wires going from the fuse to the igniters of the opening devices of the throwing blocks of the second type. The projectile can be equipped with jet or ballast pulse engines to compensate for the moments that occur when opening throwing blocks of the second type. The projectile can be equipped with a composite pallet with a square socket.

The invention is illustrated by drawings:

figure 1 - the shell in the initial state;

figure 2, 3 - shell after the disclosure of blocks;

figure 4 - diagram of the action of the projectile;

5 is a shell with detachable pan.

The fragmentation-beam projectile (Fig. 1, side view) is made with a transverse square section, along the axis of the projectile there is a longitudinal support beam 1, on which central throwing blocks of the first type 2 are located with a certain distance from each other. To the edges of these blocks located on their rear side, hinged 3 connected folding throwing blocks of the second type 4. The central blocks are indicated by hatching, folding - white. In the front of the projectile there is a shock-time fuse 5, which includes a slip measurement device 6, a command receiver 7 and a head contact assembly 8. When the projectile is executed as a controlled one, it can also contain a control unit 9, rudders 10, wings 11, an engine 12. The axial clearances between the blocks are shown conditionally in an enlarged view.

Each throwing unit includes a housing 13, an explosive charge 14, and a fragmentation plate 15.

Figure 2, 3 shows the projectile with the side blocks open, 4. The side blocks are opened and locked in the open position using a mechanical or pyrotechnic system (not shown in the figures). Submission of commands from the fuse to ignite the pyrotechnic devices for opening the blocks and to detonate the central blocks is carried out electrically using the internal cavity of the axial beam 1.

The transfer of detonation from the central blocks to the lateral ones is carried out using the detonation channels 16 (Fig. 3). The dense laying of the second type of blocks on the supporting beam is provided by recesses 17 applied on their rear sides.

The fragmentation plate is made in the form of a single-layer or multi-layer set of ready-made striking elements or a plate of predetermined crushing, or a plate with spherical depressions extruded on it, facing vertices to the explosive charge. Finished damaging elements can be made of steel or heavy alloys based on tungsten in a form that ensures their tight packing in a set.

The action of a projectile having a shock-temporary fuse is as follows. Before firing (starting, dropping) through the receiver, the type of action (shock or trajectory detonation) is set and in the second case a temporary setting is entered. When approaching the target, the miss value sensor determines the expected miss. With a small expected miss (the shell goes directly to the target), the temporary mechanism is blocked, and the detonation occurs due to the firing mechanism of the fuse with a direct hit.

With an average miss when approaching the target area, a temporary fuse gives a command to trigger the opening mechanism of the hinged blocks. In this case, the sequence and time intervals for opening the blocks are calculated in such a way that the opening process has a minimal effect of the incoming air flow on the deviation of the projectile from the calculated trajectory. A variant of the projectile is provided that provides compensation for moments arising from the opening of the side blocks using jet or ballast pulse engines. After opening the blocks with a temporary fuse, a command is given to detonate the charges, and each block forms an axial flow of the GGE. In case of detonation of the throwing unit, the minimum impact of the backward flying bottom of the unit and detonation products on the forward-moving fragmentation plate of the next unit must be ensured.

The firing scheme for this case is presented in Fig. 5 (D is the distance from the firing system to the target, S is the flight range to the disclosure of the blocks, R is the projectile span during the opening of the blocks, U is the distance between the projectile and the target at the time of detonation). With the expected large magnitude of the miss, the fuse automatically increases the time setting to the value of the flight time of the distance D. In this case, the target will be hit by a radial four-beam field.

During firing, the temporary channel is blocked and undermining occurs due to the operation of the firing mechanism.

An option is provided for firing and launches from large-caliber barrels (rifled and smooth) using pallets 18 (Fig. 5). The use of fragmentation-beam shells "Rugodiv" in the ammunition of large-caliber assault guns "Tver" is very promising (Ross. Patent N2213315). The pallet consists of two parts and has a square nest.
