在分析载人登月再入段应急飞行策略的基础上,对出现升力故障的弹道式应急飞行进行了仿真研究。建立了再入运动方程,通过设计再入角,对标称再入走廊及航程与应急再入走廊及航程进行了对比,对标称再入走廊设计和应急着陆场选择提出了一些有益结论。 Based on the analysis of the emergency flight strategy of the manned lunar landing reentry flight, the simulation study of the ballistic emergency flight with lift failure is carried out. The reentry equation was established. By comparing the reentry corridors with the reentry corridors and voyage re-entry corridors, the re-entry corridors were designed. Some useful conclusions were made on the design of the re-entry corridors and the selection of emergency landing sites.
