摘要
研究了利用太阳帆实现悬浮轨道附近编队飞行。考虑到相对运动距离与帆到太阳距离相比非常小,一阶近似得出了在主星坐标系中线性定常的相对运动方程。通过分析线性化的运动方程得出了相对运动的定性特征,给出了不同轨道附近的相对运动的稳定特性。讨论了原非线性相对运动方程的周期解的计算算法,给出了编队的初值条件。
The solar sails formation flying around displaced orbit is investigated in this paper. Considering that the relative distance between two sails is very small compared to the distance between the Sun and the sails, linear time invariant relative motion equations are obtained when the first order approximation is applied. The qualitative characteristic and stability of relative motion are obtained according to the linear equations. At last, the algorithm for calculating the periodic solution of original nonlinear equations is given. The initial values of natural formation flying are also given.
