摘要
对交会对接过程中目标航天器后方的一类安全撤离轨迹进行研究,针对长方形禁飞区提出两类撤离模式,并分析与禁飞区最可能相交的点的特征,通过两个定理给出这两类撤离模式自由漂移轨迹安全的充分必要条件.最后针对实际问题提出撤离方案,给出两组仿真算例,仿真结果验证了撤离方法的正确性和撤离方案的可行性.
A design method of safe retreat trajectory for rendezvous behind a keep-out-zone is investigated. Two safe retreat modes are provided for a rectangular keep-out-zone around the target spacecraft, and characteristics of those possible points intersectant to the keep-out-zone are analyzed. Two theorems on sufficient and necessary conditions about safety of the free-flying trajectories of two retreat modes are presented and proved. Finally a retreat scheme is designed based on practical engineering, and two simulation examples are given to demonstrate validity of the retreat method and feasibility of the retreat scheme.
