Abstract :
Interior ballistic model of spinning solid rocket motor (SRM) and a method of internal ballistic calculation were presented in this paper. The internal ballistic calculation equations were solved by fourth-order runge-kutta method. The calculation program and the law of pressure along with time were obtained. Through contrasting with test data, correctness of the theoretical model was verified. Finally, experimental methods and data disposal were discussed. The results indicate that the designed motor operates normally, the interior ballistic performance meets requirements, and the experiment can be done repeat. Furthermore, the experimental results have the guidance meaning for the pre-research design of spinning SRM.
