摘　　要：针对M型固体火箭发动机的具体结构,建立了其在储存环境条件下的传热模型,并进行了计算,分析了环境温度变化对“压差法”气密性检查结果的影响,验证了采用“压差法”对固体火箭发动机进行气密性检测的可靠性。Based on the structure of a kind of solid rocket motor, the model of heat transfer of the motor in the storage environment was given, and calculated with the method of simulation. The influence of temperature on the result of the airtight test was analyzed, and the reliability of the method of pressure discrepancy test for airtightness was validated.
