Interlayer structure for reducing interlayer strain of double-pulse solid engine

Abstract

The invention discloses an interlayer structure for reducing interlayer strain of a double-pulse solid engine. The interlayer structure separates a grain into I pulse grains and II pulse grains, the interlayer structure comprises an axial interlayer and a radial interlayer, the radial interlayer is wrapped on the inner circumferential surface of the II pulse grain, the tail part of the radial interlayer is overlapped on the inner side of the head part of the axial interlayer, the axial interlayer is transited from the head part arc to the tail part, and the axial interlayer is wrapped on the opposite end surfaces of the II pulse grain and the I pulse grain. According to the interlayer structure, the hoop strain of the radial interlayer can be reduced, so that the strain of the interlayer of the double-pulse solid engine is reduced.

Description

technical field [0001] The invention relates to the technical field of solid motors, in particular to an interlayer structure for reducing the strain of an interlayer of a double-pulse solid motor. Background technique [0002] In order to meet the power requirements of the new generation of tactical missiles, a dual-pulse solid motor with energy management advantages came into being. By designing the I / II pulse working time and pulse interval time, the energy during the whole working process of the engine can be effectively distributed without increasing the missile In the case of the maximum speed, the average speed of the missile can be effectively increased, which can better meet the energy controllable demand of the missile power plant and improve the combat effectiveness of the missile. [0003] The compartment isolation method is one of the advanced solutions to realize the double pulse technology of solid motor, which has the advantages of light negative mass and hig...

AI Technical Summary

Problems solved by technology

The radial compartment of the conventional compartment type double-pulse solid motor is as follows figure 1 As shown, the radial compartment A and the axial compartment B are designed with a vertical structure, the structure of the I / II pulse grain is simple, and the adjustment ability of the internal ballistic is weak; under the same quality requirements of the I / II pulse grain, the radial Longer interlayer lengths, resulting in greater hoop strain under pressure and greater susceptibility to failure
