摘要: 对不同贮存期的某型固体火箭发动机进行了零部件的功能试验和燃烧室的解剖试验。根据试验测得的推进剂化学性能和力学性能的变化,对不同贮存期的发动机进行了内弹道和结构完整性计算。比较理论分析和综合性能试验的结果,对该型发动机服役寿命进行了评估,发现决定其寿命的因素是粘接界面的失效。

Abstract: The functional tests of the parts and units and the dissection tests of the combustion chambers had been done for the solid rocket motors which were in variable storage times. According to the change of the chemical properties and the mechanical properties obtained from the tests, the simulation of interior ballistic and the structural integrity analysis for these motors were conducted. By investigating the results from the theoretical analysis and the comprehensive property tests,the service life of these motors were evaluated and it was found that the factor determing the service life of these motors is the misfunction of the binding interfaces.
