本文介绍了固体发动机推力终止过程理论分析及预估的各种方法,并对它们的优缺点和应用场合,以及某些问题进行了讨论,文中在指出现有计算方法均不能解释和预估推力终止过程中出现的一系列压力脉冲现象同时,介绍了这一问题的冷模拟实验结果。 In this paper, the theoretical analysis and prediction of the thrust termination of solid-state engines are introduced. Their advantages, disadvantages, applications, and some problems are discussed. It is pointed out that none of the existing methods can explain and estimate the thrust A series of pressure pulse phenomena occurred during the termination process At the same time, the cold simulation results of this problem are introduced.
