Description

The alleged invention relates to military equipment, namely to high-explosive fragmentation warheads of rockets and can be used in multiple launch rocket systems.

The object of the invention is a high-explosive fragmentation warhead equipped with a fragmentation bushing with finished fragments, which has increased safety during operation and combat use as part of a missile. A feature of such high-explosive fragmentation warheads is that their normal functioning and effectiveness depends largely on the choice of the design and layout scheme to ensure the required operational safety.

A known design of a high-explosive fragmentation warhead containing a housing, a blast of explosive explosives and a fragmented bushing with fragments placed between them (see, for example, Unmanned aerial vehicles. - M.: Mechanical Engineering, 1967, p. 362 / Ed. Chernobrovkina L.S.), adopted as an analogue.

This design allows you to ensure the necessary effectiveness of the combat use of high-explosive fragmentation warheads at the target.

However, this design does not allow to achieve the required operational safety in the composition of a rocket, the level of which primarily depends on the uniformity of the blasting explosive when it is poured into the body of the head part, which prevents the explosive from entering the gap between the body of the head part and the fragmentation sleeve.

Thus, the objective of this technical solution was to ensure the necessary effectiveness of the combat use of a high-explosive fragmentation warhead at the target.

Common features with the high-explosive fragmentation warhead proposed by the authors are the presence of a shell, fuse, charge of a blasting explosive and a fragmentation sleeve with finished fragments placed between the body and the charge of explosive.

The closest in technical essence and the achieved technical result is a high-explosive fragmentation shell containing a shell, fuse, explosive charge and located between the shell and the explosive charge fragmentation sleeve with finished fragments, fastened by a material with a specific acoustic resistance less than that of the finished material fragments according to the patent of the Russian Federation No. 2106596, MPKF 42 B 13/32, published on 03/10/98, adopted by the authors for the prototype.

This design of a high-explosive fragmentation warhead makes it possible to increase the efficiency of the fragmentation action of the warhead at the target by fastening the finished fragments with polyethylene having a minimum specific acoustic resistance.

For reasons that impede the achievement of the following technical result when using the well-known high-explosive fragmentation warhead adopted for the prototype, the known design does not solve the problem of ensuring the required operational safety.

Common features with the high-explosive fragmentation warhead proposed by the authors are the presence of a shell, fuse, explosive charge and a fragmentation bushing with ready-made fragments located between the shell and the explosive charge.

Unlike the prototype, in the proposed high-explosive fragmentation warhead, the cylindrical part of the casing has an internal thinning, in which a thrust ring and a fragmentation sleeve with finished fragments are placed, the front end of which is pressed against the thrust ring by a threaded bottom, while the amount of thinning is 0.1-0.5 of the wall thickness of the housing, and the thickness of the thrust ring is 0.8-1.2 of the thickness of the fragmentation sleeve.

It is this that allows us to conclude that there is a causal relationship between the totality of the essential features of the claimed technical solution and the achieved technical result.

These signs, distinguishing from the prototype, and to which the requested amount of legal protection applies, in all cases are sufficient.

The objective of the proposed invention is the creation of high-explosive fragmentation warhead equipped with a fragmentation bushing with ready-made fragments, increased safety during operation and combat use of multiple launch rocket systems.

The specified technical result during the implementation of the invention is achieved by the fact that in the known high-explosive fragmentation warhead containing a body, fuse, explosive charge and located between the body and the explosive charge fragmentation sleeve with finished fragments, the feature is that on the cylindrical part of the housing internal thinning is performed, in which a thrust ring and a fragmentation sleeve with finished fragments are placed, the front end of which is pressed against the thrust ring by a threaded bottom, elichina necking is 0.1-0.5 housing wall thickness, and the thickness of the thrust ring is equal to the thickness of 0,8-1,2 fragmentation sleeve.

A new set of structural elements, as well as the presence of connections between them, allows, in particular, to create a kink on the cylindrical part of the body of the internal thinning with a thickness of 0.1-0.5 of the wall thickness of the body, in which the thrust ring and fragmentation sleeve with finished fragments are placed the contact surface of the explosive with the body of the head part, preventing leakage of the explosive when it is poured into the gap between the body of the head part and the fragmentation sleeve. If the thinning value is less than 0.1 of the wall thickness of the case, it is possible for the explosive to fall when it is poured into the gap between the body of the head part and the fragmentation sleeve. When the amount of thinning exceeds 0.5 of the wall thickness of the body, there is a likelihood of mechanical destruction of the thinned body of the head during its operation as part of a rocket, the front end of the fragmentation sleeve is pressed against the thrust ring with a thickness equal to 0.8-1.2 of the thickness of the fragmentation sleeve, threaded provide bottomless endless placement of the fragmentation sleeve in the head housing. When the thickness of the thrust ring is less than 0.8 or more than 1.2 times the thickness of the fragmentation sleeve, there is a difference in the surfaces of the ring and the sleeve, which leads to heterogeneity of the filling of the body of the head with explosive in the area of such a difference, which adversely affects the operational properties of the head, the essence of the invention consists that a high-explosive fragmentation warhead containing a shell, fuse, explosive charge and, located between the shell and explosive charge, a fragmentation bushing with finished fragments, unlike the prototype, according to the invention, internal thinning is performed on it on the cylindrical part of the housing, in which a thrust ring and fragmentation sleeve with finished fragments are placed, the front end of which is pressed against the thrust ring by a threaded bottom, while the amount of thinning is 0.1-0.5 of the wall thickness of the body, and the thickness of the thrust ring is 0.8-1.2 of the thickness of the fragmentation sleeve.

The essence of the alleged invention is illustrated in the drawing, where the drawing shows a General view of a high-explosive fragmentation warhead.

The proposed high-explosive fragmentation warhead contains a housing 1, a fuse 2, an explosive charge 3, a fragmentation sleeve 4, pressed against the thrust ring 5 by a threaded bottom 6.

High-explosive fragmentation warhead works as part of a missile as follows.

After starting the rocket engine, the projectile accelerates to maximum speed, resulting in a flight to the target along a ballistic trajectory. When the fuse 2 is in contact with the target, explosive 3 is initiated, the case 1 is destroyed, and the finished fragments are scattered from the fragmentation sleeve 4.

The implementation of high-explosive fragmentation warhead in accordance with the invention provides uniform filling of the body of the warhead with explosive, which leads to increased safety of the warhead during its operation as part of the projectile.

The specified positive effect is confirmed by flight tests of prototype high-explosive fragmentation warhead made in accordance with the invention.

Currently, design documentation has been developed for a high-explosive fragmentation warhead, and mass production is planned.
