摘要:
针对环月轨道(Low Lunar Orbit,LLO)共面交会支持的“人货分离”载人登月任务,提出了一种任务窗口与轨道一体化规划方法。分析了基于LLO共面交会的“人货分离”载人登月任务的基本流程和工程约束;针对任务各阶段窗口与轨道求解问题,提出了以动力下降时刻为迭代初值的窗口规划策略,并建立了高精度模型下的环月轨道、双二体模型下的人员和货物运输轨道规划模型。以载人月球探测中国科学家命名的环形山为假想背景,给出仿真实例,仿真结果验证了文章所提方法的正确性,为探月工程任务提供了一种有效的窗口与轨道设计工具。

Abstract:
An integrated design method for manned lunar mission trajectory and trans-lunar window is proposed for the manned lunar mission supported by low lunar orbit (low lunar orbit, LLO) coplanar encounter. Firstly, the basic processes and engineering constraints of the manned lunar mission supported by LLO rendezvous are analyzed. Secondly, in view of the problem of computing windows and trajectories for the tasks in different stages, a window planning strategy by iterating the power down time is proposed. Thirdly, an orbit planning model including the LLO established in the high precision model, as well as the manned and cargo trajectories established in double two-body model, is constructed. Finally, the reliability and effectiveness of the approach proposed in this paper are demonstrated by the simulation tests on the crater named after a Chinese scientists.The researching findings are useful for manned lunar orbit and window design.
