摘要： 从一假想的卫星的返回轨道分析出发,论述了返回式卫星回收系统的“过载一时间”控制方案,说明了该方案是无人卫星回收的一种简便的、可行的控制方案。建议对某些卫星采用长的抛罩后的滑行段,以降低开伞马赫数及速压。

Abstract: In this paper, a "overload-time" control program of returnable satellite is discussed on the basis of the return trajectory analyses for a imaginary satellite. It is explained that this control program is simple and feasible for the recovery of unmanned satellite.In this paper, it is proposed that a longer non-therm-shield coast flight phase can be adopted for some satellites in order to reduce the Mach number and the dynamic pressure when the parachute is employed.
