近地一次环月两次交会的载人登月任务规划

Manned lunar mission planning based on once low earth orbit and twice low lunar orbit rendezvous and dockings

针对近地一次环月两次交会的载人登月任务飞行阶段多、周期长、约束复杂,导致各阶段飞行窗口与轨道衔接匹配复杂的难题,提出分层分解、正逆向结合的全任务标称飞行窗口与轨道衔接设计策略。介绍近地一次环月两次交会的载人登月任务飞行模式特点和应用前景,假定任务基本需求与工程约束,仿真验证所提方法的有效性,可以快速规划出近地一次环月两次交会的载人登月任务飞行轨道与窗口。

Aiming at the complex problem of matching flight windows and orbits connection due to the multiple flight stages,long duration and complicated constraints of the manned lunar mission based on once LEO(low earth orbit)and twice LLO(low lunar orbit)RVDs(rendezvous and dockings),a design strategy of connecting the full-mission nominal flight windows and orbits with the combining layered decomposition and the forward and reverse design approach were proposed.The characteristics and application prospect of the manned lunar mission based on once LEO and twice LLO RVDs were introduced,and the basic mission requirements and engineering constraints were supposed.The effectiveness of the proposed method was verified by simulation.The nominal flight orbital elements and windows of the manned lunar mission based on once LEO and twice LLO RVDs can be responded rapidly.
