对中国小行星探测任务的目标选择技术和转移轨迹剖面进行了系统研究。提出了一套完整的选择任务目标和设计转移轨迹的方法。首先,在选择任务目标时,讨论了一些被视为科学动机的因素。然后,在分析目标的可达性时,提出了多重重力辅助策略,而不是经典策略。通过选择和估算,获得兼顾科学价值和技术可行性的合适的、可能的目标。在设计小行星探测任务转移轨迹时,提出了一种重力辅助天体选择方法。最后根据任务约束,给出了探索小行星的2年ΔV-EGA轨迹剖面。通过分析轨迹剖面,发现了意想不到的结果:轨迹将经过两颗主带小行星。因此,最初的建议被扩展到多次飞越任务。它增加了小行星任务的科学回报。
Technique of target selection and profiles of transfer trajectory for Chinese asteroid exploring mission are studied systemically. A complete set of approaches to selecting mission targets and designing the transfer trajectory is proposed. First, when selecting a target for mission, some factors regarded as the scientific motivations are discussed. Then, when analyzing the accessibility of targets, instead of the classical strategy, the multiple gravity-assist strategy is provided. The suitable and possible targets, taking into account scientific value and technically feasible, are obtained via selection and estimation. When designing the transfer trajectory for exploring asteroid mission, an approach to selecting gravity-assist celestial body is proposed. Finally, according to the mission constraints, the trajectory profile with 2-years ΔV-EGA for exploring asteroid is presented. Through analyzing the trajectory profile, unexpected result that the trajectory would pass by two main-belts asteroids is found. So, the original proposal is extended to the multiple flybys mission. It adds the scientific return for asteroid mission.
