Description

    The invention relates to the field of weapons, namely to fragmentation and high-explosive fragmentation warheads with contact fuses of instant action, mainly to shells, mines and warheads of missiles with hinged firing trajectories, wearable grenade launchers, aerial bombs.

Such warheads are a cylindrical body with a bottom filled with an explosive charge with an instantaneous contact fuse. The case is made with voltage concentrators in the form of a grid of special notches for regulating the size and number of fragments (see, for example, the design of fragmentation warheads selected as an analogue and presented in the Fundamentals of the Design of Powder Missile Shells V.D. Kurov, Yu. M. Dolzhansky, Oborongiz, 1961).

As the closest analogue of the prototype, a warhead with spherical finished striking elements was selected (see, for example, US patent No. 3945321 (A), IPC F42B / 32, F42B 12/02). It consists of a thin-walled cylindrical body, a bottom, a head fairing with a fuse, an explosive charge and spherical finished striking elements located between the charge and the shell of the projectile.

The disadvantages of the known fragmentation and high-explosive fragmentation warheads include their low efficiency due to the fact that:

- during the explosion of fragmentation and high-explosive fragmentation warheads, the bulk of the fragments - spherical finished striking elements are located in a narrow sector (about 70% of the fragments) in the radial direction from the warhead, while in the warheads with contact fuses of instant action the projectile fires directly at the ground and with the hinged trajectory, when the warhead approaches the surface of the earth with angles close to 90 °, a significant part of these fragments goes into the ground;

- with a large charge weight and a large number of spherical ready-made striking elements, such warheads have a small reduced destruction zone.

The technical task of the present invention is to eliminate the disadvantages of the known fragmentation and high-explosive fragmentation warheads, namely, increasing the efficiency of hitting the target by reducing the loss of spherical finished striking elements due to the deviation of the dispersion zone of the spherical finished striking elements from the ground when triggering fragmentation and high-explosive fragmentation warheads parts with mounted shooting trajectories, while reducing the weight of the charge and the number of spherical ready-made lesions impeding elements in the warhead.

The solution to this problem is achieved by the fact that in the warhead, consisting of a cylindrical body, the bottom of the warhead, the head fairing, charge, contact fuse and spherical ready-to-hit elements located between the charge and the body of the warhead, the charge is new in the form of a thick-walled glass with a bottom facing the side of the fuse, and an open end to the bottom of the warhead, while the thickness of the side wall of the charge is made variable, with its increase from the middle of the length of the strips and charge toward the fuse, and the bottom charge - with increasing thickness from the center to the periphery.

The invention is illustrated in the graphic material of figures 1, 2 and 3.

Figure 1 shows the design of the warhead fragmentation or high-explosive fragmentation.

Figure 2 - zone of expansion of spherical finished striking elements in the well-known fragmentation and high-explosive fragmentation warheads.

Figure 3 - zone of expansion of spherical finished striking elements in the fragmentation and high-explosive fragmentation warheads of the invention.

The warhead contains:

1 - contact fuse instant action;

2 - head fairing;

3 - cylindrical body;

4 - spherical finished damaging elements;

5 - charge in the form of a glass with an increase in the thickness of its side wall 9 from the middle of the length of the charge cavity 8 towards the fuse 1 and the bottom 10 of the charge with an increase in thickness from the center to the periphery;

6 - the bottom of the warhead;

7 - filler in the form of glue (for example, K-153 epoxy adhesive or KGE-3/16 sealant);

8 - the internal cavity of the charge;

9 - side wall of the charge;

10 - bottom of the charge.

The work of the warhead of the proposed design is as follows.

When the warhead approaches the surface of the earth, a contact fuse 1 is triggered and the charge 5 detonates from it. The products of the explosion of the bottom 10 of the charge 5 propagate along the surface of the earth, creating a charge 5 on the side wall 9 flying away under the action of the products of the explosion.

As follows from the description of the device of the invention:

- charge in the form of a thick-walled glass with a bottom facing the fuse, and an open end to the bottom of the warhead, i.e. the concentration in the head of the warhead of the explosive charge due to the larger thickness of the charge in the cross section along the length of the charge allows you to create a powerful reflected wave at the moment the charge is triggered on the surface of the earth, deflecting the flow of spherical finished striking elements from the earth's surface;

- the execution of the side wall of the charge of variable thickness with increasing it from the middle of the length of the cavity of the charge towards the fuse, and the bottom of the charge with increasing thickness from the center to the periphery additionally contributes to the deviation of the flow of spherical finished striking elements from the surface of the earth;

- execution of the charge in the form of a thick-walled glass with the bottom facing the side of the fuse, and the open end to the bottom of the warhead, the thickness of the side wall of the charge variable with increasing it from the middle of the length of the cavity of the charge towards the fuse, and the bottom of the charge with increasing thickness from center to the periphery, all this, taken together, allows to reduce the overall weight characteristics of fragmentation and high-explosive fragmentation warheads and their combat effect while reducing the charge weight and the number of spherical ready-made striking elements vnost increase the reduced lesion area.

This is especially important when developing wearable grenade launchers, for which warheads are developed in the same caliber and weight, for example thermobaric, smoke, incendiary, high-explosive fragmentation, etc. while maintaining external ballistic characteristics and when using one unified warhead corps.

Thus, the present invention allows to increase the effectiveness of hitting a target by reducing the loss of spherical finished striking elements due to the deviation of the dispersion zone of spherical finished striking elements from the ground when firing fragmentation and high-explosive fragmentation warheads with hinged shooting paths while reducing the weight of the charge and the number of spherical ready-made striking elements in the warhead.
