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.
Based on the Hill equation, the safety strategy of circular orbital double-pulse wind-up is studied.Firstly, the model of double-pulse wind-around is given, and the trajectories of fly-bys that do not enter the spherical safe zone are obtained through simulation traversal, then these safe Orbit around the fly, fuel consumption, the relationship between the tracker and the initial distance of the target three surfaces, and then get the relationship curve under the critical safety conditions and fit the relationship expression, and finally to the proposed The analysis of the error shows that the degree of deviation from the trajectory is very small.
