摘要
航天器单脉冲机动异面可达域为分析异面机动任务的可行性提供了依据,有助于提高航天器异面轨道机动任务的设计效率。为求解航天器单脉冲机动异面可达域,首先分析了目标平面的可达性问题。在目标平面可达的情况下,将可达域分为两个区域,并给出两个区域存在的条件。在此基础上根据几何关系,将涉及改变轨道面的可达域问题简化为仅在平面内机动的可达域问题。对于平面可达域问题,提出了一种高效率的精确计算方法。由此,进一步给出了航天器单脉冲机动异面可达域的求解算法,并进行了仿真验证。结果表明,上述方法所得可达域与拟合法所得结果一致,可以精确给出航天器单脉冲机动异面可达域。
The non-coplanar reachable domain of spacecraft with a single impulse provides a basis for analyzing the feasibility of spacecraft maneuvering missions and improves the design efficiency of spacecraft maneuvering missions.In order to solve the non-coplanar reachability domain of spacecraft with a single impulse,the reachability of the target plane is analyzed.In the case that the target plane is reachable,the reachable region is divided into two regions,and the existence conditions of the two regions are given.On this basis,according to the geometrical relation,the reachable domain problem involving changing the orbital plane is simplified to the reachable domain problem involving only maneuvering in the plane.An efficient and accurate calculation method for plane reachable domains is proposed.Therefore,the algorithm for solving the non-coplanar reachable domain of spacecraft with a single impulse is given and verified by simulation.The results show that the reachable domain obtained by this method is consistent with that obtained by the fitting method,and the reachable domain can be obtained precisely by this method.
