摘要

本文介绍了南京航空航天大学团队参加第12届全球轨道优化竞赛的结果和设计方法。为了解决可持续小行星采矿问题，我们重点分析了约束条件和涉及的小行星；选择一组易于执行采矿任务的候选小行星；建立了采用相位指示器、多目标波束搜索和遗传算法确定采矿船小行星访问顺序的算法流程；通过间接方法和全局优化对低推力轨迹进行优化。此外，提出了一种中心节点法，以简化设计过程，降低执行重复小行星交会任务的计算成本。竞赛中开发的方法可以通过20艘采矿船开采161颗小行星，总收集质量为11,513公斤。

GTOC12: Results from Nanjing University of Aeronautics and Astronautics

This paper presents the results and design methods of team Nanjing University of Aeronautics and Astronautics in the 12th edition of the Global Trajectory Optimization Competition. To address the problem of sustainable asteroid mining, we focus on the following: analyzing the constraints and asteroids involved; selecting a candidate set of asteroids for which mining missions can be performed easily; establishing an algorithmic flow using phasing indicators, multiobjective beam search, and a genetic algorithm to determine the sequence of asteroid visits for mining ships; and optimizing low-thrust trajectories via an indirect method and global optimization. In addition, a central-node method is proposed to simplify the design process and reduce the computational cost of performing repetitive asteroid-rendezvous missions. The methods developed in the competition enable the mining of 161 asteroids via 20 mining ships, with a total collected mass of 11,513 kg.
