Multi-size pre-control fragment for fragment warhead

By prefabricating a multi-size pre-controlled groove array configuration on the warhead shell to form multi-size fragments, the problem that a single fragment cannot strike multiple targets in the existing technology is solved, achieving efficient damage to different targets and improving damage effectiveness and metal utilization.

AI Technical Summary

Technical Problem

Existing fragmentation warheads can only produce fragments of a single size, making them ineffective at striking multiple targets and resulting in reduced damage effectiveness.

Method used

A multi-sized pre-controlled groove array configuration is pre-fabricated on the warhead casing to form three different sizes of fragments, including small, medium and large fragments. By carving grooves of different sizes in different areas of the casing, it is ensured that the grooves do not interfere with each other, preventing premature breakage and forming multi-sized pre-controlled fragments.

Benefits of technology

It has achieved effective strikes against multiple targets, improved the destructive power of fragmentation warheads, met the kill requirements of different targets, and increased the utilization rate of projectile metal and the density of damage radius.

Abstract

The invention belongs to the technical field of fragment warheads, and particularly relates to a multi-size pre-control fragment for a fragment warhead, according to the fragment warhead, a notch groove is prefabricated in a shell, a multi-size pre-control groove array structure is formed, and the multi-size pre-control fragment is formed during striking; in the multi-size pre-control groove array configuration, grooving is carried out on different areas of the shell according to different sizes, at least three kinds of pre-control grooves of different sizes are formed, and the pre-control grooves correspond to fragments of three different sizes; the fragments with the three different sizes comprise the small fragment (1) with the smallest size, the middle fragment (2) with the middle size and the large fragment (3) with the largest size. After the fragment structure is adopted, the metal utilization rate of a projectile body is increased, multiple targets are damaged by one warhead, the dense killing radius of the warhead and the density of a penetration steel plate both meet index requirements, certain allowance exists, and the damage efficiency of the fragment warhead is greatly improved.
