摘要:

固体推进剂裂纹扩展的预测是固体火箭发动机中的一个十分重要的问题,这个问题的解决在很大程度上要依赖于试验研究.本文主要介绍国外在某些典型推进剂的裂纹扩展的试验研究中所采用的推进剂试件、试验方法、试验条件和试验结果.

Abstract:

Prediction of crack growth, in solid propellants is one of very important problems in solid rocket motors. Its solving relys on experimental investigation to a great extent.This paper mainly shows some propellant samples which were used in foreign test of crack growth of typical propellants as well as their experimental methods,conditons and results.
