RU174313U1 - High-explosive fragmentation projectile - Google Patents

Abstract

The utility model relates to artillery ammunition and can be used to suppress and destroy concealed and uncovered manpower, enemy firing points, destroying field defenses, making passages in barriers, suppressing enemy rear lines (railway junctions, headquarters, troop concentrations).

 However, in a high-explosive fragmentation projectile, low damage by target fragments and low armor penetration due to the fact that detonation is initiated from the head to the bottom, and the bottom of the shell remains undisturbed, that is, the potential resource of the entire shell is not revealed.

 The aim of the invention is to increase the damaging effect of fragments, increase armor penetration and crushing of the entire projectile.

 The task is achieved in that detonation in a high-explosive fragmentation projectile will be initiated from the bottom and will move in the direction of projectile movement. The projectile operates as follows. An impulse arrives from the head fuse through the detonation cord, pressed into the mass of the explosive, to the detonator capsule located in the bottom of the projectile along with the detonation lens, which forms a detonation front in the direction of the head.

Thus, we obtain an increase in the density of damage by fragments, an increase in the speed of inertia of the projectile by concentrating the fragments in a narrower focused solid angle. A fragmentation field will form from the bottom in the direction of the warhead, and all fragments formed during crushing of the hull will move towards the target.

Description

The utility model relates to artillery ammunition and can be used to suppress and destroy concealed and uncovered manpower, enemy firing points, destroying field defenses, making passages in barriers, suppressing enemy rear lines (railway junctions, headquarters, troop concentrations).

Known high-explosive fragmentation shell (122 mm), consisting of the following parts: a steel body with a chamber under an explosive charge. There is a threaded hole in the head of the case for screwing in the fuse. On the cylindrical part of the shell of the projectile there are two centering thickenings, a lead belt made of copper or ceramic ceramics, a burst charge of TNT.

However, in this high-explosive fragmentation projectile, low damage by the target fragments is due to the fact that detonation is initiated from the head to the bottom, and the bottom of the shell remains unbroken, that is, the potential resource of the entire shell is not revealed.

In addition, a high-explosive fragmentation shell (120 mm) is known, consisting of the following parts: a steel case with a chamber for an explosive charge. In the head of the projectile is a fuse. On the cylindrical part of the shell of the projectile there are two centering thickenings and a leading belt made of the shell of the shell with ready-made rifling.

However, in this high-explosive fragmentation projectile, low armor penetration is due to the fact that detonation is initiated from the head to the bottom.

The objective (technical result) of the invention is to increase the damaging effect with fragments and crushing the entire projectile.

The problem is achieved in that in a high-explosive fragmentation projectile consisting of a steel body containing a warhead consisting of a fuse. In the cylindrical part of the projectile there is a leading belt and two centering thickenings, in the shell of the projectile there is a chamber with a pressed explosive, characterized in that a pre-contact fuse located in the head of the projectile is introduced into the projectile, and in the cylindrical part is the lead belt made of the shell of the shell, detonation cord, pressed into the mass of explosive, detonator capsule located in the bottom of the projectile along with the detonation lens.

The drawing shows the proposed high-explosive fragmentation projectile containing 1 - pre-fuse, 2 - steel shell of the projectile, 3 - explosive charge, 4 - lead belt made from the shell of the shell, 5 - detonation lens, 6 - detonation cord, 7 - capsule - detonator. The projectile operates as follows. An impulse arrives from a 1 - head fuse through a 6 - detonation cord, pressed into the mass of the explosive, to 7 - a detonator capsule located in the bottom part of the projectile together with a 5 - detonation lens, which forms a detonation front in the direction of the head part.

The technical result is an increase in the damaging effect of fragments, an increase in the speed of inertia of the projectile, by concentrating the fragments in a narrower focused solid angle. A fragmentation field will be formed from the bottom in the direction of the warhead and all the fragments formed during the crushing of the body will move towards the target.

Claims (1)

A high-explosive fragmentation shell consisting of a steel body, containing a head part consisting of a fuse, a cylindrical part with a leading belt and two centering bulges, in the shell body there is a chamber with a pressed explosive, characterized in that a pre-fuse located in the shell is inserted the head part of the projectile, and in the cylindrical part, a lead belt made of the shell of the projectile, a detonation cord, pressed into the mass of the explosive, a detonator capsule located in constant of the projectile with the detonation lens.
