Abstract: 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.
