丁羟推进剂库房贮存与加速老化规律研究

摘要

采用库房贮存与加速试验的方法,研究了丁羟推进剂在库房贮存与加速老化环境下的规律,得到了丁羟推进剂加速老化与库房贮存的试验数据.利用秩相关系数检验方法对2组试验数据进行了相关性分析,并分析了推进剂老化失效模式和贮存环境对推进剂贮存寿命的影响.%Storage and accelerated aging rule of HTPB propellant were investigated by using storage and accelerated test method. The correlativity of the two methods was analyzed using the obtained test data with rank correlation coefficient method. The aging pattern of propellant and the influence of environment on storage life of propellant were analyzed.
