月球轨道交会任务的远程导引变轨策略研究

对国内外月球轨道交会远程导引段变轨策略的2~5脉冲变轨方案进行了比较分析,在考虑月球轨道交会飞行任务测控资源有限和航天器所带燃料受限等特点的基础上,确定了我国月球轨道交会远程导引段的变轨策略为4脉冲方案;并介绍了在4脉冲基线轨道方案的基础上,进行标称轨道设计和月面上升窗口初步分析的结果。研究结果可为我国月球轨道交会对接任务提供参考。

Study of Orbit Maneuver Strategy for Lunar Orbit Rendezvous Mission

The paper compares the 2～5 impulse schemes of the phasing strategy for lunar orbit rendezvous missions.Based on the consideration of the characteristics of lunar orbit rendezvous missions such as limited tracking resources and fuel consumption constraint,the 4-impulse scheme is selected as the phasing strategy.A brief review is given on the nominal orbit design and preliminary analysis of lunar surface ascent window,based on the discussion of the 4-impulse scheme.This research can serve as a good reference for the future lunar orbit rendezvous missions of China.
