| 摘 要： | 针对航天器共面及异面气动辅助轨道转移的轨迹优化问题，利用高斯拟谱法将原始连续两点边值问题离散化并转化为等价的非线性规划问题，应用SNOPT算法对此非线性规划问题进行求解．同时分析了对应于不同变轨角度时大气内飞行轨迹、飞行速度以及热流峰值的变化规律．

| Abstract: | Aiming at the aero-assisted orbital transfer （AOT） problem, a Gauss-pseudospectral method is used to convert an original AOT problem to a discrete nonlinear programming problem, and then the SNOPT algorithm is applied to solve it, thus getting optimal state trajectories. At the same time, variations of spacecraft＇ s flight trajectory, velocity and heat-flow peak value are analyzed when the inclination changes. |

| Keywords: | aero-assisted orbital transfer pseudospectral method trajectory optimization |
