论空间交会中的径向连续推力机动与N次推力机动

文章从相对运动和绝对运动两方面分析径向小推力连续机动在空间交会V-bar接近中的运动规律，对冲量型、连续型和N次推力三类径向推力策略的性能进行比较。径向小推力连续机动的相对运动轨迹呈“旋轮线”型式。N次机动策略变轨速度总和与冲量型转移及连续推力机动所需的变轨速度相等，轨道控制能力提高，视界角比冲量型转移的视界角小，转移时间比连续型推力所需时间减少，且能适应范围更广的推力阶。N次推力机动策略综合性能优良。

Analysis of Constant Continuous Radial Thrust and N-thrusts in Space Rendezvous

The absolute motion(orbital motion)and relative motion of space rendezvous V bar approach using constant continuous radial thrust and N thrusts are investigated, calculated and compared with impulsive thrust transfer. The results show that the N thrusts transfer has a better performance.
