小型固体火箭发动机低压自毁效果研究

Study on the low-pressure self-destruction effect of an analog solid rocket motor

根据导弹自毁装置低爆炸危险性要求,开展了低压自毁效果研究,进行了2发Φ260mm发动机自毁模拟试验。试验结果表明,低压状态下非点火发动机可以自毁,低压状态壳体全切开方案自毁效果及前封头切开方案自毁效果均能够满足安全自毁的要求。

Based on the requirements of low explosion hazard, a study of the low-pressure self-destruction effect and two Φ260 mm solid rocket motor self-destruction simulation tests were carried out. Results show that the non-ignition motors at low-pressure can be destructed. The low-pressure self-destruction effect of both the whole-shell-cutting scheme and the forward-dome-cutting scheme can satisfy the safe self-destruction demand.
