Abstract

A practically useful algorithm for constructing the trajectory of returning from a Lunar orbit to the Earth using one-impulse and three-impulse maneuvering schemes is presented. This algorithm forms the return trajectory to the reentry point of the atmosphere satisfying the given constraints, taking into account the current ephemeris and the fact that the gravitational fields of the Moon and Earth are noncentral. The computer simulation results make it possible to draw conclusions about the advantages and expedience of using a particular maneuvering scheme.

使用三脉冲机动方案从月球轨道返回地球大气的折返点

摘要

提出了一种实用的算法，该算法利用一脉冲和三脉冲机动方案构造从月球轨道返回地球的轨迹。考虑到当前星历和月球和地球的引力场不是中心的这一事实，该算法形成了满足给定约束的返回大气点的返回轨迹。计算机仿真结果使得可以得出有关使用特定机动方案的优势和便利性的结论。
