摘要
针对太阳系边界探测,利用形函数轨迹优化算法快速生成连续小推力航天器引力辅助逃离太阳系的三维轨迹,实现在有限燃料条件下的超远距离探测.通过对比有无引力辅助设计的仿真结果,证明了引力辅助技术在逃离太阳系过程中的有效性.仿真结果表明,基于贝塞尔形函数方法的连续小推力轨迹优化算法可以高效地设计出引力辅助逃离太阳系的合理三维初始轨迹,对于初始探测任务的快速设计和分析具有重要意义.
Abstract
For the exploration of the Solar System boundaries,the shape-based trajectory optimization algorithm is used to quickly generate three-dimensional gravity-assist trajectories of continuous low-thrust spacecraft escaping from the Solar System,achieving ultra long range exploration under limited fuel conditions.The effectiveness of gravity-assist technology in escaping the Solar System is demonstrated by comparing simulation results with and without gravity-assist design.The simulation results show that the continuous low-thrust trajectory optimization algorithm based on the Bezier shape-based method can efficiently design a reasonable three-dimensional initial gravity-assist trajectory for escaping from the Solar System.This is of great significance for the rapid design and analysis of initial detection missions.
