摘要

网关是阿耳特弥斯计划的一个关键要素，该计划的目标是在 2030 年代中期建立可持续的月球存在。本文研究了从 "网关 "到低月球轨道（LLOs）的最小燃料双脉冲轨道转移，最长飞行时间为 48 小时。本文分析了两种不同的情况：(i) 具有上升节点自由右升角（RAAN）的目标轨道；(ii) 具有指定 RAAN 的目标轨道。对于情况(i)，利用基于启发式算法的全局优化技术来获得最小燃料转移量。考虑了目标轨道的几种倾角。对于情况(ii)，提出了两种不同的技术：(a)一种纯粹的启发式方法，和(b)一种基于朗伯解的局部细化的半分析方法。在包括所有相关扰动的高保真框架内，对所有情况进行了数值传播。对不同策略和相关数值结果进行了比较。

Optimal Impulsive Orbit Transfers from Gateway to Low Lunar Orbit

Gateway represents a key element of the Artemis program for the upcoming lunar exploration aimed at establishing a sustainable presence by the mid-2030s. This paper investigates minimum-fuel bi-impulsive orbit transfers from Gateway to low lunar orbits (LLOs) with a maximum time of flight of 48 h. Two distinct scenarios are analyzed: (i) target orbits with free right ascension of the ascending node (RAAN), and (ii) target orbits with specified RAAN. For case (i), a global optimization technique based on a heuristic algorithm is exploited to obtain the minimum-fuel transfer. Several inclinations of the target orbit are considered. For case (ii), two distinct techniques are proposed: (a) a purely heuristic approach, and (b) a semi-analytical method based on local refinement of a Lambert-based solution. Numerical propagations are conducted in all scenarios in a high-fidelity framework that includes all relevant perturbations. A comparison between the different strategies and the related numerical results is provided.
