吸气式激光推进中推力形成过程的研究

将激光推进中的推力形成过程与传统化学火箭发动机中的推力形成过程进行了比较，分析了两者之间的异同；对激光引致的激波与喷管壁面流固耦合而产生的推力和气体从喷管出口端反冲而获得的推力分别进行了计算，计算结果表明：2种推力在一个力作用周期内的平均推力相等，也即力学效应相同；研究所得的结论为进一步研究吸气式激光推进机理提供有用的参考。

Study of Thrust Forming Process in Air-breathing Laser Propulsion

The thrust forming process of laser propulsion was compared to that of chemical rocket engine with the discussion of their similarities and differences. The thrust generated by the coupling process of laser-induced shock waves and nozzle wall and that caused by ejecting of the high temperature gases from the nozzle exit were computed separately. The study results show that the mean thrust of the two types in a force action period is equal to the identical mechanical effect. The conclusion of this paper will provide some meaningful information for the further study of the operation mechanism of air-breathing laser propulsion.
