月球返回再入着陆场位置选择限定因素分析

月球返回再入着陆场不仅影响月-地返回转移和返回再入飞行,同时也影响整个月球飞行任务的规划和设计.文章首先分析了航天器与地-月间的相对位置关系;结合月-地返回转移及返回再入轨道特性,理清了月球、地球着陆场和航天器三者在惯性空间内相对位置的内在约束关系;最后分析并通过仿真研究,明确了制约航天器返回再入着陆场位置选择的限定因...

Analysis on Selection Considerations of Lunar Exploration Mission Reentry Landing Site

Lunar exploration mission reentry landing site affects not only the trans-Earth and reentry trajectories,but also the whole mission analysis and design.So its location determination is very important.This paper studies the relative positions between the vehicle,the Moon and the Earth,and the characters of the trans-Earth and reentry trajectories,analyzes some considerations of lunar reentry landing site latitude and its center position,and then gives some useful conclusions which will be very useful to the analysis and design of the future lunar soil sampling missions and manned lunar missions.
