摘要

本文侧重于对垂直着陆可重复使用运载火箭的返回轨迹进行任务分析，包括返回发射场（RTLS）和下段着陆（DRL）回收策略。主要目标是评估从主发动机截止点（MECO）开始的推进剂最优再入和着陆轨迹的任务性能，同时考虑推进剂预算和峰值进入条件限制。因此，建立了性能包络和可行性区域，以全面评估所需的推进剂，并比较各种 MECO 条件下的恢复策略。结果表明，在推进剂消耗方面，DRL 战略实现了更高的效率，而在分散的 MECO 条件方面，则具有更大的鲁棒性。

Mission Performance Assessment of the Recovery and Vertical Landing of a Reusable Launch Vehicle

This paper focuses on the mission analysis of the return trajectory of a Vertical Landing Reusable Launch Vehicle, both for Return-to-Launch-Site (RTLS) and DownRange Landing (DRL) recovery strategies. The main objective is to assess the mission performance of propellant-optimal re-entry and landing trajectories from the Main Engine Cut-Off (MECO) while considering propellant budget and peak entry conditions constraints. As a result, performance envelopes and feasibility regions are built to comprehensively assess the required propellant and compare recovery strategies across a broad spectrum of MECO conditions. The results show that the DRL strategy achieves higher efficiency concerning the propellant consumption and a larger robustness regarding the dispersed MECO conditions.
