Abstract: In this paper, a one-dimensi.onal quasi-steady internal ballistic calculation method universal to any grain and the corresponding grain calculation method are given and developed.The matching problem between.the grain calculation, is solved.A computer program is made and used to predict the internal ballistic performance of actual motor.The results of the numerical solution are also comp-ared with the results of zero-dimensional internal ballistic calculation as well, as experiment results.
