| 摘 要： | 针对载人月球软着陆进程中，由载人飞船发动机失效引起的任务中止问题，首先分析主发动机失效可能引起的撞月轨道、环绕轨道、逃逸轨道等轨道类型及其特点；然后分析了中止任务执行的前提条件及中止过程的导航制导要求，在此基础上，考虑二体模型，提出普适的共面软着陆中止轨道计算方法；最后，在考虑登月飞船生保系统时间限制条件下，给出下降级主发动机失效情况下，撞月轨道的中止仿真算例。仿真结果表明，该方法可以实现登月飞船软着陆制动故障情形下的任务中止，能够确保飞船安全返回环月轨道。

| Abstract: | In case of mission abort of Manned Lunar Soft Landing caused by main engine failure, the abort fashion and the corresponding style of blooey orbits were analyzed. Based on the two body hypothesis, an all-purpose caleulative method was proposed for abort trajectories design in coplanar Lu- nar Soft Landing Mission, and characteristic of abort trajectories was analyzed. The numerical simu- lation was conducted under the condition of the given parameters of Lunar Surface Access Module. The results indicated that the method of abort trajectories design was effective for the abort of manned lunar soft landing mission, and the astronauts could be send back to the circle lunar orbit |
