关于非开普勒轨道的讨论

A Discussion on Non-Keplerian Orbit

讨论了非开普勒轨道问题的形成、提出及其应用。首先引述了开普勒三大定律,说明了其作为天文观测结果的创造性概括能够描述行星的运动学原理;然后提出了非开普勒轨道问题,它是人造卫星可控性的必然结果。叙述了典型的非开普勒轨道问题,包括航天器在单心引力场中的运动(即二体问题)和多心引力场中的运动(即多体问题),作为特例研究了螺旋变轨爬升轨道和悬挂轨道。最后提出了非开普勒轨道的应用,包括动能拦截问题,多星编队、组网与重构问题,系统整体组合优化机动问题等。

The conception of Non-Keplerian orbit was described and its applications were discussed. Firstly, as a direction the Keplerian Law was given which in fact as a very creative summarization of the observation results of planets, and it can describe the kinematical principle of planet motion. Then, the concept of Non-Keplerian orbit is given, which is the inevitable result of artificial satellite controllability. In succession, the typical problems of non-Keplerian orbit are described, including kinematical problem of spacecraft in single center gravitation field （viz. two-body problem） and in muilt-center gravitation field（viz, multibody problem） . The spiral climbing orbit and suspension orbit are studied as specific case. Finally, the applications of non-Keplerian orbit were put forward, including problem of kinetic energy interception, satellite formation and reconfiguration, optimal maneuvering of system integrated configuration.
