Description

The invention relates to ammunition technology, and more particularly to fragmentation munitions with a controlled field of destruction.

In the patent, selected as the closest analogue (RU 2148244, figure 4), the design of the projectile is proposed, in which, depending on the application conditions, various combinations of axial and circular fragmentation fields can be implemented. The projectile comprises a housing, a bursting unit located therein, consisting of a metal shell and an explosive charge with a detonator located in the inner cavity of the shell, a layer of ready-made striking elements laid on the outer surface of the shell, a bottom powder charge, a fuse, either temporary or non-contact, or command type with a striking mechanism, while the fuse can be placed both in the head and in the bottom of the projectile. The control system is configured to undermine the explosive block both after pushing the block out of the shell of the shell, and when it is inside the shell of the shell. In the first case, an axial lesion field is formed, in the second - circular.

When a tensile block is pushed out of the housing, the inertial pressure of the equipment of the block leads to a noticeable radial expansion of the thin-walled shell of the block, and, as a result, to a possible jamming of the block in the housing and rupture of the latter by the gases of the bottom powder charge. Another disadvantage of the bottom location of the powder charge is that with the head location of the fuse used in the vast majority of designs of fragmentation munitions, the projectile must have an electrical or pyrotechnic connection between the head fuse and the igniter of the bottom powder charge. The constructive implementation of such a connection presents certain technical difficulties. The present invention addresses these drawbacks.

The technical solution consists in the fact that a projectile with ready-made striking elements includes a body, a bursting block placed therein, consisting of a metal shell, an explosive charge placed in the inner cavity of the shell, a layer of ready-made striking elements laid on the outer surface of the shell, an explosive fuse trajectory type, and the device for ejection of the explosive block from the shell of the projectile, while the projectile and the explosive block are equipped with bottom stabilizers of the opening type, and the ejection device is placed in the goal oval part of the projectile and electrically or pyrotechnically combined with a fuse. According to the technical solution, the powder ejection charge or other device of a similar purpose is transferred from the bottom of the projectile to the head, which, when the unit is thrown forward along the projectile, leads, on the one hand, to the replacement of compressive axial stresses in the wall of the unit by tensile ones, which eliminates their possible buckling and loss stability, and on the other hand, allows you to transfer the ignition pulse from the main fuse to the separation device on a short path, which greatly simplifies the design and increase Vaeth her safety.

The invention is illustrated by drawings: figure 1 - an example of a projectile for a tank smoothbore gun; figure 2 is a complete section of a bursting unit with a separation device ballast type; figure 3 - bursting unit with a cumulative charge; 4 is a diagram of the action of the projectile with the formation of the axial field.

The tank projectile for the smoothbore gun (Fig. 1) has a housing 1, in the rear part of which there is a stabilizer 2 with feathers 3. The explosive block 4 is placed in the internal cavity of the housing 1, it contains a metal shell of a block 5 with a charge of explosive 6, a caliber head part 7 and a stabilizer 8. The ready-made damaging elements 9 (in this case, the GGE of a spherical shape) made, for example, of steel or tungsten-based heavy alloys are stacked in the annular gap between the shell of the projectile and the shell of the explosive block and or uranium. The space between the GGE can be filled with lightweight aggregate. More rational is the implementation of the GGE form, ensuring their tight laying on the surface of the explosive block.

The head part 7 of the explosive block contains a detonator 10, an annular powder charge separation 11 located in an annular chamber located at the junction of the shell of the projectile and the explosive block, a pyrotechnic channel 12, an impact trajectory fuse 13 with a command receiver 14, a head contact assembly 15 and an impact mechanism inertial and delayed action.

Figure 2 shows a complete section of the bursting block. The stabilizer unit 8 concentrically sliding type shown in the open state. In this embodiment, the unit is ejected from the shell of the projectile due to the shooting of the goods placed in the chambers 17, inclined to the axis of the projectile, using powder charges 18. The option also differs by the presence of annular shelves 19 on the outer surface of the shell of the unit.

Figure 3 shows an embodiment of the bursting block with placement in front of the cumulative charge 20.

The projectile is as follows. Before firing through the command receiver 14, a setting for the type of action is introduced, and when using a temporary blast, also the flight time of the projectile before rupture. The projectile is multifunctional and allows you to implement three main types of action (see RF patent No. 2148244):

A. With the release of the explosive block and the formation as the main axial field of defeat (figure 4) - (with three types).

B. Without ejection of a bursting block, with the formation of a circular lesion field (with three types).

B. With partial extension of the sliding block.

In total, 7 types of actions can be implemented. The conditions under which it is advisable to use various types of actions, as well as various versions of the bursting unit, are described in detail in RF patent No. 2148244.

As already mentioned above, the main advantages of the proposed projectile compared to the prototype (US Pat. RF No. 2148244) is an increase in reliability and a significant simplification of the design. The decrease in the rate of ejection of the explosive block compared to the prototype, due to the decrease in the path of movement of the block in the shell of the projectile, does not play a significant role for tank shells, used mainly at short ranges and maintaining high speed on the entire trajectory.
