大长径比固体火箭发动机旋转发射过程中装药结构完整性

Structural Integrality Analysis of High Length-Diameter Ratio SRM Grain on Rotary Launching Process

摘要:

以防空导弹大长径比双推力固体火箭发动机装药为研究对象,分析了导弹旋转发射出筒过程中承受的各类载荷。通过计算装药的应力—应变场,发现了装药的危险部位,进而分析了燃烧室发生高压爆炸原因。

Abstract:

A kind of anti-aircraft missile solid rocket motor with high length-diameter ratio was taken as the ob. ject of study, all kinds of load on the grain during the process of the missile rotary launching out of the con. tainer was analyzed in detail. By computing the stress-strain field of the grain, the danger part of the grain was found, and the cause of the combust chamber high pressure explosion was analyzed.
