固体火箭发动机压强调节稳态过程数值模拟

NUMERICAL SIMULATION OF STEADY PROCESS FOR THRUST MODULATED SRM

对涡流阀调节固体火箭发动机压强的稳态过程进行了理论研究。采用稳态分析方法，对涡流阀结构参数设计进行了探讨，得出了一些有用的结论。当绝热条件越好时，调节效果更佳。

The steady process of solid rocket motor modulated by the vortex valve is investigated theoretically.The design of structural parameters for the vortex valve is considered with the method of steady analysis,and some useful conclusions are drawn.The modulation effect is much better if we have better heat-insulating situation.Reduction of the pressure exponent of the main chamber grain helps increasing the modulation effect.
