Memory alloy type pressure relief structure of insensitive ammunition

Abstract

The invention discloses a memory alloy type pressure relief structure of insensitive ammunition. The memory alloy type pressure relief structure of the insensitive ammunition comprises an ammunition bottom, memory alloy type springs, sealing plugs, an air guide plate and an air-permeable buffer piece; the air guide plate and the air-permeable buffer piece are sequentially arranged in the ammunition bottom from bottom to top; coaxial circular holes are formed in the centers of the air guide plate, the air-permeable buffer piece and the ammunition bottom; a plurality of grooves are evenly formedin the ammunition bottom in the radial direction, the grooves penetrate through the side wall of the ammunition bottom and form pressure relief holes; the sealing plugs are arranged on the pressure relief holes; the grooves do not communicate with the circular hole in the center of the ammunition bottom; the memory alloy type springs are arranged in the grooves, one ends of the memory alloy typesprings are fixedly connected with the ammunition bottom, and the other ends of the memory alloy type springs are fixedly connected with the sealing plugs; and a plurality of air guide holes are formed in the air guide plate, and the air guide holes communicate with the grooves. The memory alloy type pressure relief structure of the insensitive ammunition can achieve the effective pressure reliefwhen the ammunition is subjected to thermal stimulus.

Description

technical field [0001] The invention belongs to the field of pressure relief at the base of bullets, in particular to a pressure relief structure for memory alloy insensitive ammunition. Background technique [0002] With the development of high technology and the increasingly complex battlefield environment, the requirements for ammunition and weapons in modern warfare are becoming more and more stringent. The warhead is required to have the characteristics of long range, high power, and high energy. At the same time, in order to improve the survivability of one's own combatants, the ammunition system must have the characteristics of insensitivity or insensitivity. In order to improve the insensitivity of ammunition, domestic and foreign studies mainly focus on three aspects: energetic materials, system design, and packaging protection. The main technologies include insensitive explosives and charge technology, warhead pressure relief technology, and warhead thermal / mechani...

AI Technical Summary

Problems solved by technology

These pressure relief structures basically consider opening holes at the bottom of the bomb bottom for pressure relief. On the one hand, the structural strength of the bomb is reduced, and on the other hand, it is easy to cause gunpowder gas to enter the inside of the bomb body during firing, causing a chamber explosion accident.
