| 摘 要： | 研究了与木星探测相关的轨道设计问题.重点关注木星探测轨道与火星、金星等类地行星探测轨道的不同及由此带来的轨道设计难点.首先分析了绕木星探测任务轨道的选择.建立近似模型讨论了向木星飞行需要借助多颗行星的多次引力辅助,对地木转移的多种行星引力辅助序列,使用粒子群算法搜索了2020年至2025年之间的燃料最省飞行方案并对比得到了向木星飞行较好的引力辅助方式为金星-地球-地球引力辅助.结合多任务探测,研究了航天器在飞向木星途中穿越主小行星带飞越探测小行星的轨道设计.最后,给出2023年发射完整的结合引力辅助与小行星多次飞越的木星探测轨道设计算例.

| Abstract: | The trajectory design for Jupiter exploration mission is investigated in this paper. The differences between Jupiter exploration trajectory and Mars or Venus exploration trajectory are mainly concerned about.Firstly,the selection of the Jupiter-centered orbit is analyzed based on the Galileo Jupiter mission.As for the Earth-Jupiter transfer orbit,the fuel consumption of the direct transfer is too large.So the energy-saving technologies such as the planetary gravity assist should be used for the trajectory to the Jupiter.The different sequences of planetary gravity assist for the trajectory from the Earth to the Jupiter are examined by applying the Particle Swarm Optimization(PSO).According to the searching results,Venus-Earth-Earth gravity assist(VEEGA) is the most effective gravity-assist sequence for the Jupiter mission.During the Jupiter mission,the spacecraft will pass though the main asteroid belt which is between the orbits of Mars and Jupiter,and may encounter several asteroids.The Jupiter mission is able to combine with the main-belt asteroid flyby missions.The design method of the intermediate asteroid flyby trajectory is also considered. At last,an entire designed trajectory for the Jupiter mission launched in 2023 is presented. |
