| 摘 要： | 本文研究了推力固定条件下，从圆轨道进入共面圆轨道一次入轨最节省燃料的推力方向控制策略。这类问题都可归结为两点边值问题，对自由初值的选取作了讨论，并采用打靶法迭代求解。计算了从停泊轨道到同步转移道以及两个过地圆轨道之间的最优转移，获得满意的结果。

| Abstract: | The minimum-fuel coplanar orbit transfer with a fixed thrust is studied here.The circular (or elliptical) orbit transfering to coplanar circular(or elliptical) orbit is discussed, and the corresponding transversality conditions are analysized in detail. The optimal problems of different conditions can be included in the Two-Point Boundaty Value Problems (TPBVP), which can be solved by the target shooting method. Finally, several numerical examples of optimal orbit transfer are calculated and discussed. |
