针对载人登月短期全球访问任务,月面上升过程存在上升舱与返回舱异面交会问题。以减小调面机动燃料消耗为目标,利用三垂线定理给出上升轨道与目标轨道的最小平面夹角(楔角)求解公式,考虑应急返回任务需求,以降低整个任务期间最坏的平面夹角为目标,给出全月面到达着陆轨道与上升轨道倾角求解方法。仿真结果表明,所提方法计算简单,精度高,可为载人登月任务设计和分析提供参考。
In response to the mission of manned lunar landing on a short-term trip to the moon, the ascent of the lunar surface is exacerbated by the disagreement of the ascent and return of the moon. In order to reduce the maneuvering fuel consumption, the formula of solving the minimum plane included angle (wedge angle) between the rising orbit and the target orbit is given by using the three vertical line theorem. The emergency return mission needs to be considered in order to reduce the worst plane during the whole mission As the goal, the method of solving the full lunar landing arrival orbit and rising orbit inclination is given. The simulation results show that the proposed method has the advantages of simple calculation and high precision, which can provide reference for the design and analysis of manned lunar landing mission.
