针对2020-2040年载人小行星探测任务,研究了探测目标选择与轨道优化设计问题。首先,针对已编目的近地小行星,综合考虑绝对星等、燃料消耗等多方面因素与约束,给出了适合载人探测任务的候选小行星序列;然后,构建了载人小行星探测任务轨道的设计模型,采用参数优化算法对探测轨道进行了设计;进一步,为了获得最优探测轨道,利用主矢量原理对探测轨道进行了优化。该研究可为载人小行星探测任务设计提供有价值的参考。
Aiming at the task of manned asteroid exploration from 2020 to 2040, the exploration of target selection and orbit optimization design are studied. Firstly, aiming at the cataloged near-Earth asteroids, the candidate asteroid sequences suitable for the manned exploration mission are given considering various factors and constraints such as absolute magnitude, fuel consumption and so on. Then, a manned asteroid exploration mission Orbit design model, using the parameter optimization algorithm for the design of the detection orbit; further, in order to obtain the optimal orbit, using the principle of principal vector to optimize the orbit. This study can provide valuable reference for the design of manned asteroid exploration mission.
