摘要

摘要: 为评估长期贮存后固体火箭发动机安全性的变化,对贮存时间为18年的某型固体火箭发动机进行了解剖.测试并比较了经过长期贮存后发动机药柱的力学性能和各种感度,而后进行了长期贮存后推进剂和发动机试件的枪击试验,各种试验项目中均利用贮存期为4年的推进剂方坯进行对比.结果表明:长期贮存后推进剂热安全特性变化不明显,但撞击感度和摩擦感度明显增加并且在枪弹高速冲击下破碎严重,长期贮存后发动机在模拟枪击试验中表现出爆炸倾向,使用安全性大大降低.

Abstract: The safety of a long stored solid rocket motor was evaluated.The solid rocket motor (SRM) stored 18 years was disassembled.The safety of the long stored SRM was evaluated experimentally.Firstly,the mechanical properties and the sensitivity of the propellant were measured,and the popping experiment of the propellant and grain was carried out.The propellant stored 4 years was adopted as comparative sample.This shows that the mechanical sensitivity of the propellant was increased.The aged propellant is broken up badly in popping experiment.The RSM stored 18 years has a tendency to explosion under the popping condition.The vulnerability of the SRM stored 18 years has a remarkable change.
