摘　　要：在一定假设条件下,建立了再入飞行器的一阶近似运动方程。为了确定通用航空飞行器的再入走廊,推导了热流峰值、最大过载和动压峰值与再入角、升阻比、倾斜角等参数之间的解析表达式。通过仿真,给出了在不同飞行状况下的计算曲线,并得到相应结论。The first order motion equations of reentry aerocraft for use is established under some supposed conditions. In order to determine the reentry corridor of common aero vehicle, the analytic expressions between thermal spike, maximum overload and dynamic pressure peak and reentry angle, lift-drag ratio and roll angle are deduced. The calculation curves under different flight cases and corresponding results are presented by mathematical simulation.
