| 摘 要： | 以Hill方程为基础对圆轨道近距离双脉冲绕飞安全策略进行研究.首先给出双脉冲绕飞的模型,通过仿真遍历得到不会进入球形安全区的绕飞轨迹,然后绘制出这些安全的绕飞轨迹所对应的绕飞时间、燃料消耗、追踪器与目标器的初始距离三个量之间的关系曲面,进而得到临界安全条件下的关系曲线并拟合出关系表达式,最后对拟合误差进行分析发现导致轨迹偏离的程度很小.

| Abstract: | Based on the Hill equation, the safety strategy of double-impulsive fly-around process is researched. Firstly, the model of double-impulsive fly-around is given and all the fly-around trajectories outside the global safety area are obtained by ergodic simulation. Then a curved surface can be plotted, which expresses the relations among fly-around time, the consumption of the fuel and the starting point. Furthermore, the curve which is critically safe can be obtained and fitted. Finally, the fitting error is analyzed and it is showed that the trajectory deviates slightly. |
