摘要
本文采用圆锥曲线拼接方法,建立了垂直着月轨道的数学模型,给出了垂直着月轨道运动特性的简明分析结果。在适当近拟后,获得了垂直着月轨道的解析解,为初步轨道设计提供了实用的工程方法。
A patched-conic technique is used to formulate the mathematical model and to make an explicit analysis of the normal-impact transfer trajcctory to the moon. Some approximations are required in order to obtain the analytical solutions of the normal-impact transfer trajectory to the rnoon. lt is a practical engineering method for preliminary trajectory designing.
