针对月球探测器大角度异面动力上升入轨问题,提出了一种共面间接上升策略。该策略基于显式制导(E制导)律和轨道机动原理,经过共面动力上升、轨道滑翔2个过程和2次轨道机动,实现大角度异面上升。仿真结果表明:1)E制导律均能实现共面和异面的在线实时制导;2)与传统的平面修正上升策略相比,燃料一定时,轨道转移方法发射窗口明显较大,这在实际应用中应对突发紧急情况随时准备月面起飞有重要的工程意义。
Aiming at the problem of large-angle and non-uniform power rising of lunar probe into orbit, a coplanar indirect rising strategy is proposed. Based on the explicit guidance (E-guided) law and orbital maneuvering principle, this strategy achieves large-angle caustic rise after two processes of coplanar power uplift, orbital gliding and two orbital maneuvers. The simulation results show that: 1) E-Guidance Law can both achieve real-time guidance of coplanar and heterogeneous surfaces; 2) Compared with the traditional strategy of plane correction, the launch window of the orbital transfer method is obviously larger when the fuel is fixed, It is of important engineering significance to be ready for lunar surface take-off in emergency situations.
