| 摘 要： | 双二体模型是深空探测初步轨道设计普遍采用的假设.本文针对月球探测器从月球驻留轨道返回的任务,对直接返回型轨道和间接返回型轨道,建立了基于直观六参数的返回轨道模型.通过对直观六参数及出口点时刻这些可选参数的分析,得到了约束条件和可选参数的定性关系,易于搜索满足要求的返回轨道.最后针对两种返回轨道类型的算例表明该方法是有效的.

| Abstract: | Idealized double two-body model is the universal hypothesis in the preliminary trajectory design of deep space.Based on this hypothesis,a return trajectory model with six independent parameters of lunar spacecraft from parking moon orbit including direct return trajectory and indirect return trajectory is designed.Through analysis of the six independent parameters and the time of outlet point,general relationships between constraint and free parameters are given to easily search certain trajectories.Finally,effectiveness of the proposed approach is validated by examples including two types of return trajectory. |
