固体火箭发动机内弹道性能预示的一种方法

A METHOD FOR PREDICTION OF INTER BALLISTIC PERFORMANCE OF SOLID ROCKET MOTOR

介绍一种在固体火箭发动机药型及其尺寸一定的条件下,利用发动机静止点火试验结果预示其内弹道性能的方法。利用这一方法,可以计算在概率条件下发动机的内弹道参数及总体参数的散布。

A method for prediction of p-t curve and performance parameters of solid rocket motor is presented in this paper. Based on the results of static firing test, and keeping the configuratioa and diameters of the motor grain unchanged, this method can be used with confindence to calculate the distribution of main performance parameters of the motor such as F, m etc.
