A pressure relief structure of memory alloy insensitive ammunition

Abstract

The invention discloses a pressure relief structure for memory alloy type insensitive ammunition, which comprises a bullet bottom, memory alloy type spring, sealing plug, air guide plate, and breathable buffer sheet; the air guide plate and breathable buffer sheet are sequentially arranged from bottom to top It is arranged in the bottom of the bullet; the center of the air guide plate, the breathable buffer sheet and the bottom of the bullet is provided with a coaxial round hole; the bottom of the bullet is evenly arranged with a plurality of grooves along the radial direction, and the grooves pass through the bottom of the bullet The side wall forms a pressure relief hole; the sealing plug is arranged on the pressure relief hole; the groove is not connected to the center hole of the bottom of the bullet; the memory alloy spring is arranged in the groove, and one end is fixedly connected with the bottom of the bullet. The other end is fixedly connected with the sealing plug; the air guide plate is provided with a plurality of air guide holes, and the air guide holes communicate with the groove; the pressure relief structure of the present invention can realize the effective pressure relief of the ammunition under thermal stimulation.

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.
