基于长方体禁飞区的安全绕飞轨迹设计

摘要

Based on the Hill equation,a design method of double-impulsive fly-around trajectory is given on the basis of rectangular keep out zone.With dynamics model transformed,the relation of the variables of the model is deduced.On this basis,the theorems are proved,and then safety restrictions are given.Furthermore,we can get run-of-mill design methods of safe fly-around trajectories between V-bar direction and arbitrary directions in orbital plane.Lastly,this method is showed to be feasible by simulations about two kinds of typical fly-around trajectories,as well as simulation about fly-around trajectory between V-bar direction and arbitrary direction.%以C-W方程为基础针对圆轨道近距离双脉冲绕飞问题,研究基于长方体禁飞区的安全绕飞轨迹设计方法.针对双脉冲绕飞动力学模型中的变量进行代数变换,在此基础上对变量间的关系进行推导,证明部分变量在特定区间范围内具有单调性的定理;给出保证绕飞轨迹安全的约束条件,进而结合推导出的定理和安全约束条件得到轨道面内全方位安全绕飞轨迹的一般性设计方法.通过针对以目标器正后方为绕飞起点的两种典型绕飞以及到任意方位的绕飞进行仿真,验证方法的有效性.
