| Abstract: | A physical and mathematical model for numerical simulation of working process in star grain solid rocket motor has been set up.Some calculation results are given.Empirical formula for sensitivity of burning rate to acceleration in the swirling solid rocket motor is obatined from several experiments.Meanwhile the full-scale star grain swirling solid rocket engines were also tested.In comparison with the measured test data the simulation results are consistent with the measured pressure-time curves. |
