| 摘要: |
| 对于月面中高纬度着陆且定点返回地球中高纬度着陆场的载人登月任务而言，月面着陆窗口与定点返回轨道设计存在耦合关系，这是工程任务面对的关键技术之一。针对任务背景及约束条件，建立月面着陆窗口与定点返回轨道求解数学模型；通过数值求解着陆窗口与返回轨道参数规律，并从空间几何关系分析耦合机理；以2025年载人月面虹湾探测为例，给出了着陆窗口与定点返回轨道求解流程及验证算例。计算结果经商业软件STK校验正确，表明该方法是一种简捷精确的载人登月任务规划方法，可在未来载人登月工程任务规划时直接使用。 |

| Abstract: |
| For the manned lunar landing mission that lands on the moon high latitude destination and returns to earth high latitude recovery field, a design of moon landing window and point return orbit is coupled in complexity, so it is one of the key technologies in the engineering task. In view to task demands and engineering constraints, the mathematical models for finding lands window and designing point return orbit were established in the first place; Secondly, by solving the rules of landing window and point return orbit parameters, the coupled geometrical principle was analyzed; Taking a mission that lands on Sinus Iridium in 2025 for example, the strategy of coupled design landing window and the point return orbit were given, which was provided by validation example. The verification by commercial Software STK(system tool kits, by AGI company) of simulation results is correct, the proposed strategy is a simple and precise method for planning manned lunar landing mission, which can be used in the future manned lunar landing mission directly. |
