| 摘 要： | 通过数值模拟和试验研究，分析了喷口遮挡对姿控火箭发动机性能的影响。结果表明，当发动机喷口被遮挡时，姿控发动机不能跟随控制指令产生所需的反向推力，其稳定弹轴的能力减弱，从而影响火箭弹的落点精度。

| Abstract: | The effect of the blocked spouts on the performance of an attitude control rocket motor was analyzed by using numerical simulation and test. The results show that the attitude control motor can not generate required reverse thrust consistent to control signal when some spouts of attitude control motor are blocked. As the decrease of the capability for stabilizing the axis of rocket, the delivery accuracy is reduced. |
