摘　　要：针对大载荷航天器回收过程中,单独使用圆形降落伞工作时的不可控和单独使用翼伞工作时开伞减速慢的不足。在圆伞与翼伞的基础上,将两者进行规划组合设计,提出了圆形混合翼伞的设计理念及优化方法,并通过仿真研究了优化前和优化后的圆形混合翼伞的气动性能,仿真结果说明了优化后所得椭球形混合翼伞具有优良的滑翔性能,能够满足航天助推器回收过程中对伞的系统要求,解决了单独使用圆形降落伞工作时的不可控和单独使用翼伞工作时开伞减速慢的问题。In order to solve the problem of uncontrollability when using single round parachute and slow deceleration when using parafoil alone in the recovery process of heavy load spacecraft.On the basis of circular parafoil and parafoil,the design concept and optimization method of circular hybrid parafoil are put forward,and the aerodynamic performance of circular hybrid parafoil before and after optimization is studied by simulation.The results of computer simulation shows that the optimized circular-mixed wing umbrella has good controllability and excellent glide performance,and it can meet the requirements of the umbrella system during the recovery process of spacecraft,the problem of uncontrollable operation when using the circular parachute alone and the problem of slow down when using the wing umbrella alone are solved.
