空间交会对接寻的段三次变轨策略分析

Analysis of Three Orbital Maneuver Strategies in Homing Phase of Rendezvous Docking

根据第一次变轨采用地面或自主引导,以及后两次变轨策略,提出了采用Hohmann变轨与CW双脉冲最优变轨、CW双脉冲变轨+中途一次修正,以及CW三脉冲最优变轨的空间交会对接寻的段三次变轨方案。仿真分析了方案中Hohmann变轨椭圆转移轨道远地点高度、CW双脉冲转移时间、总转移时间或第二次变轨时间与总特征速度的关系,并给出寻的段变轨策略建议。

The three orbital maneuver strategies in homing phase of rendezvous docking,which were Hohmann and CW 2-pulse optimal maneuver,CW 2-pulse optimal maneuver + a midway amendment,and CW 3-pulse optimal maneuver,were put forward according to ground guide or independent guide in first maneuver and strategies in next two maneuvers in this paper.The relation of apogee altitude of ellipse transfer orbit in Hohmann transfer,transfer time in CW 2-pulse optimal maneuver, total transfer time or transfer time of the sec...
