| 摘 要： | 利用发动机地面试验结果，引入广义的压强系数和推力系数，计算了发动机的特征速度、喷管喉部面积等参数。在此基础上利用随机试件和标准发动机的相关参数预示了发动机的压强、推力、流量及其积分。通过算例可以看出。此发动机内弹道性能工程预示方法简单实用，预示精度满足要求。

| Abstract: | The characteristic velocity, area of nozzle throat and other parameters are calculated by using the static test results of solid rocket motor (SRM) and introducing generalized pressure coefficient and thrust coefficient. Based on this , SRM' s pressure, thrust, mass flow rate and their integration sum are predicted with correlation parameters of random specimen and standard motor. The results show that the engineering method is simple and useful, and the prediction accuracy meets demand. |
