The invention discloses a parachute capable of avoiding winding during parachute opening. The parachute comprises a parachute canopy and parachute cords and further comprises an elastic constraint piece, and the elastic constraint piece is in a ring shape, surrounds the middle parts of the parachute cords in the length direction and binds the parachute cords which are arranged in sequence; and the elastic constraint piece and the parachute cords are only in contact without mutual restraining connection, and the fracture bearing force of the elastic restraining pieces is smaller than the tension force formed by the parachute cords when the parachute is opened. The elastic constraint piece is specially designed to be of various structures, and is suitable for various umbrella shapes and various working conditions. In the parachute packaging process, the parachute cords can be treated more normatively and orderly so as to guarantee that the parachute cords are placed in a parachute pack orderly. When the parachute is opened, the opening force formed by the parachute canopy driving the parachute cords is dozens of times larger than the breaking force capable of being borne by the elastic constraint piece such as a rubber cord, the rubber cord can be broken and fall off automatically, and the parachute opening speed is not affected. Materials are easy to obtain, and the original weight is hardly increased; and the process is simple and feasible, and various indexes of the parachute cannot be affected.

    本发明公开了一种避免开伞缠绕的降落伞,包括伞衣和伞绳,其中:还包括弹性约束件,弹性约束件成圈形,并围绕伞绳的长度方向的中部,捆扎住顺序摆放的伞绳;弹性约束件与伞绳之间只接触不相互约束连接,弹性约束件的断裂承受力小于开伞时伞绳形成的张力。弹性约束件特别设计有多种构型,适应了各种伞型和各种工况。本发明的在包装降落伞的过程中可以更规范有序的处理降落伞伞绳,保证伞绳在伞包内的有序摆放。在开伞时,伞衣带动伞绳所形成的张开力数十倍于如橡皮绳的弹性约束件能承受的断裂力,会撑断橡皮绳,橡皮绳自行脱落,不影响开伞的速度。材料容易获取,几乎不增加原有重量;工艺上简单可行,不会影响降落伞的各项指标。
