空天飞行器交会的轨道机动策略研究

在给出了空天飞行器(Aerospace Vehicle,ASV)的概念及任务构想之后,依据轨道动力学,结合ASV的特点,研究了ASV与目标在同一圆轨道上以及在共面不共轨圆轨道上的交会策略。其中,针对同一圆轨道上的交会分析了椭圆轨道机动和快速机动两种交会方案,对共面不共轨圆轨道上的交会讨论了霍曼轨道机动、双椭圆轨道机动以及快速机动3种交会方案。在每一种交会策略中均详细分析了交会所需的时间、速度增量以及轨线长度等。最后通过仿真分析了各种交会策略的优劣。

Study On Strategies for Rendezvous of Aerospace Vehicle

The concept and the mission scenario of the aerospace vehicle(ASV) are described in this paper.Based on the principle of orbit dynamics as well as the consideration of the characteristics of ASV,two kinds of ASV orbit rendezvous strategies are presented.One is aimed at the circumstance of coorbit rendezvous,and the other is for the coplane but non-coorbit rendezvous.For the former circumstance two kinds of projects double-ellipse orbit rendezvous and rapid orbit rendezvous are discussed,and beside these projects mentioned above,a Hohmann orbit rendezvous project is also used in the discussion of the second circumstance.For each project,the velocity increment of ASV,the time of orbit rendezvous and the length of rendezvous trajectory are calculated and analyzed in detail.The advantages as well as the drawbacks of each rendezvous strategy are demonstrated by means of simulation.
