| 摘 要： | 以变轨能量消耗最小为优化目标，应用极大值原理研究了飞行过程受过载限制和升力系数约束下的气动力辅助异面变轨问题．飞行过程分成自由弧段和约束弧段两种类型，给出了变量的微分方程和共轭变量的微分方程，讨论了升力系数和滚转角的最优表达式，给出了约束弧段起、止位置的角点条件和终端的横截条件，并给出了数值算例，结果表明过载限制对控制参数的影响较大

| Abstract: | This paper studies optimal non coplanar orbital transfer considering overload and lift coefficient constraints by applying Pontryagin maximum principle. Flying arc is divided into free and constrained subarcs. The equations of motion, the optimal expression of lift coefficient and bank angle during flight are derived. Corner conditions at the beginning and the end of the constrained subarc, and the transversality conditions at the end of flight are also discussed. Numerical results indicate that overload constraint has important influence on the control parameters. |
