Problems solved by technology

The preparation of hydride active fragments in the above method is to mix and seal the hydride and oxide into the tubular shell to prepare fragments. Since the hydride will slowly release hydrogen during storage, direct contact with ammonium perchlorate will cause potential safety hazards.

Embodiment

[0025] A new type of warhead active fragment, the active fragment includes a shell, a rare earth hydride, a strong oxidizer and an end cap;

[0026] The shell is a hollow cuboid, and there is a cross grid inside the shell, that is, the cross grid divides the inner cavity of the hollow cuboid into four cavities in the height direction of the cuboid;

[0027] The rare earth hydride is preferably cerium hydride, with a particle size of 10 μm;

[0028] The strong oxidizing agent is ammonium perchlorate;

[0029] Rare earth hydrides and strong oxidants are alternately filled in different cavities of the shell; as figure 1 shown;

[0030] The material of the shell is Ta, the wall thickness of the shell is 0.3mm, and the wall thickness of the grid is 0.3mm.

[0031] The preparation method of a novel warhead active fragment is as follows: Ta 2 o 5 The powder is mixed with a binder and water is added to prepare Ta 2 o 5 slurry. The slurry is extruded through a die and dried to ...

Abstract

The invention relates to a novel warhead active fragment as well as a preparation method and application thereof, in particular to a hydride active fragment which is packaged by a pipe with a grid inner wall and has better stability in a storage process. According to the method, the pipe with the grid inner wall is adopted, wherein hydride and an oxidizing agent are packaged into different unit cells of the pipe respectively; therefore, the purpose of improving the processing and storage stability of the active fragments of the hydride is achieved on the premise that the fragment damage effectis not affected.

Description

technical field [0001] The invention relates to a novel warhead active fragment and its preparation method and application, in particular to a hydride active fragment which is packaged by a pipe with a grid inner wall and has better stability during storage. Background technique [0002] Fragmentation is the basic damage unit of anti-personnel warhead. The anti-injury warhead is usually close to the target at a certain distance, and the explosive is detonated by the proximity fuze to generate a large number of fragments, which rely on the kinetic energy of the fragments to penetrate the anti-injury target. Since the fragments made of inert materials only rely on kinetic energy to damage the target when hitting the target, they often hit but cannot destroy the target, which cannot meet the needs of efficient damage in modern warfare. Therefore, it is hoped that the application of active fragments can increase the damage efficiency. When an ideal active fragment collides with...
