Research on Jovian System Tour Traj ectory Design
摘要
Abstract
In this paper,the primary targets and engineering constraints of a Jovian system multi-target explorationtour phase in a future Jovian system exploration and planet flyby mission are analyzed.Three candidate trajectory design schemes for the Jovian system tour are proposed to realize the detection of Jupiter's polar regions,surface fine structure and Galilean satellites.Then an improved collaborative evolutionary algorithm combining particle swarm optimization and dif-ferential evolutionary algorithm is employed to optimize the gravity-assist transfer trajectory.The total velocity increments of the three transfer schemes are 3.47 km/s,2.95 km/s and 2.48 km/s, respectively.The first transfer scheme meeting all three exploration targets,the second having lower total dose of radiation,and the third enabling multiple fly-by detection of Jupiter's polar regions and Galilean satellites.The three candidate trajectory design schemes can provide valuable reference for China's first Jovian system exploration mission.关键词
