采用非接触测量体积模量系统，测出了复合固体推进剂在不同温度下的体积松驰模量和体积蠕变柔量，并依据时间—温度等效原理迭加拟合求得了体积模量主曲线和温度移动因子的数学表达式，其结果可为发动机药柱结构完整性分析提供依据。
The bulk modulus and bulk creep compliance of the composite solid propellant at different temperatures were measured by using the non-contact measurement bulk modulus system. The bulk modulus The main curve and the temperature movement factor of the mathematical expression, the results can provide a basis for the analysis of the integrity of the engine grain structure.
