Abstract

The complex problem of constructing the return trajectories of a spacecraft (SC) from a circumlunar orbit before entering the Earth’s atmosphere for subsequent landing on the southern territory of the Russian Federation is considered. The problem includes two components: the choice of the conditions for the optimal impulse maneuver for the Moon–Earth flight and the determination of the descent distance from the point of entry into the Earth’s atmosphere to the given landing point. The magnitude of the impulse required and the sufficient descent distance to return on any date are estimated.

月球返回轨迹分析

摘要

考虑了在进入地球大气层以随后降落在俄罗斯联邦南部领土之前，从环绕月球轨道构建航天器 (SC) 返回轨迹的复杂问题。该问题包括两个组成部分：月球-地球飞行的最佳脉冲机动条件的选择和确定从进入地球大气层的点到给定着陆点的下降距离。估计所需脉冲的大小和在任何日期返回的足够下降距离。
