摘要
建立了星孔药柱发动机在旋转状态下工作过程仿真的物理模型和计算模型，给出了部分计算结果。通过数十发实验获得了燃速加速度敏感性的经验关系式，并且采用全尺寸发动机进行了实验验证。实验和理论预示压强时间曲线具有良好的一致性。
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.
