| 摘 要： | 分析了不同转移轨道间的性能指标,以黄道面与白道面交线作为庞加莱截面实现不同系统轨道的拼接,利用其中耗能最小的日地系稳定流形和地月系的不稳定流形设计了一条低能耗转移轨道.最后对不同轨 道进行了能量分析和对比,优化了国内提出的低能探月轨道.仿真结果表明,文中方法比直接通过霍曼转移节约21.1%的能量,对探月工程的轨道设计具...

| Abstract: | After analyzing of characteristics of different transfer trajectoies and connecting between systems by using the intersecting line of ecliptic and lunar orbit plane as poincare section,a low energy cost transfer trajectory is designed by using the low-cost stable manifold in the Sun-Earth system and unstable manifold in the Earth-Moon system.Lastly,energy analysis and compare among different trajectories are done,and some low energy cost transfer to the Moon designed by domestic scholars is optimized.The me... |
