摘要： 在给定飞行时间、着月时间、着月入射角及停泊轨道等约束条件下，建立飞月轨道数学模型；采用可变容差多面体算法及罚函数方法进行二点边值搜索，借助双二体理论近似确定迭代初始条件，得到满足要求直接命中月球的飞月轨道。

Abstract: In this paper, obtained the translunar trajectory for direct striking the moon, which satisfied some constraints including translunar flight time, lunar landing date. incidence angle of lunar landing and parking orbit, through building the mathematical models of translunar trajectory, employing varied tolerance polyhedrons algorithm and penalty functions to search two bourdary values, and using the method of a succession of two-body trajectories to determine the approximative initial values of iteration.
