| 摘 要： | 给出了一种求解同时受升力、气动加热（率）和动压约束时，航天器再入走廊的近似计算方法。文中采用格林函数法，导出了再入过程中三种典型约束（气动加热率、升力和动压）条件之间关系的近似定量描述，在该三种约束取极限的条件下求得了再入走廊的上下边界。文中还介绍了上下边界近似解及相应控制规律的结构。

| Abstract: | An approximate calculation method is given for the reentry corridor of spacevehicle with the constraints of heating rate, dynamic pressure and lift coefficient. Thequantity relationship is found among the constraints of heating rate,dynamic pressure andlift in reentry flight. Green's theorem is employed to find the upper and lower boundaries ofthe reentry corridor.The approximate analytical solutions of the boundaries of the reentrycorridor and optimal control laws are analyzed ,and some conclusions are obtained. |
