固体推进剂热安全性研究进展

Research progress in thermal safety of solid propellant

综述了近年来固体推进剂热安全性的研究进展,认为固体推进剂发生热爆炸主要是由于推进剂生热速率大于散热速率导致热量累积。影响推进剂热安全性的因素主要由其组成、形状和尺寸等内因,以及贮存环境、老化时间等外部因素构成。固体推进剂热安全性研究多采用分析仪器与实验相结合的方法,借助计算机模拟仿真研究将是今后固体推进剂性能研究的重点。

The research progress in thermal safety of solid propellant in recent years is reviewed. It is considered that the thermal explosion of solid propellant is mainly caused by the heat accumulation resulting from the fact that the heat generating rate of propellant is more than its heat dissipating rate. The factors affecting the thermal safety of solid propellant are mainly composed of the intrinsic factors such as composition, shape and size of solid propellant and the external factors such as storage environment, aging time and so on. The methods combining the analytical instruments and the experiments are usually used to investigate the thermal safety of solid propellant. The analogue simulation research using computer will be the focus of the future research on performance of solid propellant.
