Internal Ballistic Numerical Simulation of Solid Rocket Motors with Three Dimensional Grain

A new method to compute the internal ballistics of solid rocket motor with three dimensional fin cylindric grain is presented. The burning surface of three dimensional grain was calculated and the accurate computation results can be obtained by the immediate integration. The numerical simulation was carried out to compute internal ballistics by segmented analytical method in the assumption of grains steady flow of burning product. The calculated results are agreement with the experimental data.
