摘要: 行星借力技术是减小星际探测任务发射能量的有效途径,传统的行星借力模型不能保证探测器借力前后的速度矢量转角达到理想要求。为此,进行了行星借力建模,并基于该模型,推导了探测器飞出借力天体影响球的双曲线超速矢量。针对轨道设计参数的强耦合性,提出了一种全局-局部混合搜索算法,并对地球-金星-地球-火星-木星转移轨道进行了设计。仿真结果验证了轨道模型的正确性和有效性,表明该文方法可以有效地对多次行星借力轨道进行设计。

Abstract: Planetary swing-by is an effective way to reduce the launch energy for interplanetary exploration missions. However, the traditional swing-by model is difficult to match the relative velocity vector before and after the swing-by. Therefore, the swing-by model was established, and the hyperbolic velocity vector after the swing-by was also derived. Because of the strong coupling of the trajectory design parameters, a global-local hybrid search algorithm was proposed for designing Earth-Venus-Earth-Mars-Jupiter transfer trajectories. All these results certify the effectivity of the proposed model.
