The invention discloses a parachute with a variable resistance surface, which comprises a small parachute canopy 1, an elastic device 2, a follow-up pull rope 3, a large parachute canopy 4, a closing rope 5, a guide ring 6, a parachute rope 7 and a protective sleeve 8, is a novel umbrella-shaped structure, and is a parachute capable of automatically changing the resistance area according to the speed in the deceleration recovery process of an aircraft. A small resistance area is achieved in the high-speed deceleration stage, a large resistance area is achieved in the low-speed stable descending stage, and therefore parachute opening overload is effectively reduced. Therefore, the load caused in the deceleration process can be reduced.
本发明公开了一种阻力面可变降落伞,包括小伞衣1,弹力装置2,随动拉绳3,大伞衣4,收口绳5,导向圆环6,伞绳7,保护套管8,本发明是一种新型的伞形结构,是一种可以在飞行器减速回收过程中,根据速度大小而自动变化阻力面积的降落伞,在高速减速阶段有较小的阻力面积,在低速稳降阶段有较大的阻力面积,从而有效降低开伞过载。以此可以降低减速过程中带来的载荷。
