The invention discloses a variable-speed parachute, which comprises a guide parachute, parachute cloth, parachute cords, straps, a parachute pack and a parachute opener, wherein a central pull rope isarranged between the parachute cloth and a rope releasing device, and the rope releasing device is arranged between the parachute cords and the straps and the parachute pack; the rope releasing device comprises a rope releasing device shell, a pressing plate, a spring, a steel wire rope, a sleeve, a handle and a pull rod; the central pull rope and the guide parachute are sewn on the inner side and the outer side of a central point of the umbrella cloth respectively, and the central pull rope tension length mark is arranged between rope releasing device pressing plates before the parachute cloth and the parachute rope are folded; and the total length of the central pull rope is the distance from the central point of the parachute cloth to the parachute pack when the parachute is fully opened. Compared with a traditional parachute, the central pull rope and the rope releasing device are additionally arranged, the windward area of the parachute is changed by changing the tensioning length of the central pull rope through the rope releasing device, the air resistance is increased, the variable speed controllability of the parachute is achieved, the dwell time can be shortened, the landing speed and parachuting difficulty are reduced, the parachuting safety is improved, the structure is simple, and the operation is easy.
变速降落伞,包括引导伞、伞布、伞绳、背带、伞包、开伞器,在伞布与放绳器之间设置有中心拉绳,在伞绳与背带和伞包之间设置有放绳器;所述的放绳器包括放绳器壳体、压板、弹簧、钢丝绳、套管、把手和拉杆;中心拉绳和引导伞分别缝制在伞布中心点的内外两侧,在折叠伞布、伞绳前将中心拉绳张力长度标记处置于放绳器压板之间;中心拉绳的总长度为降落伞全张开状态时伞布中心点至伞包的距离。本发明比传统的降落伞增加了中心拉绳和放绳器,通过放绳器改变中心拉绳的张紧长度来改变降落伞迎风面积,增加空气阻力,实现降落伞的变速可控,可减少留空时间、降低着地速度和跳伞难度、提高跳伞的安全性,结构简单、操作简单。
