The invention provides a parachute opening control system which comprises a parachute canopy and parachute cords, the parachute canopy comprises a central parachute canopy part and a parachute canopy restraining part, the parachute opening control system further comprises a central rope, a central rope restraining belt, a force fixing rope and a central rope circular ring, the parachute canopy restraining part uses a weak-strength rope, one end of the central rope restraining belt is connected with the top end of the central parachute canopy part, and the other end of the central rope restraining belt is connected with the top end of the central parachute canopy part. One end of the central rope is provided with a central rope circular ring, the other end of the central rope penetrates through the restraint strap circular ring to be connected with an object to be thrown, a plurality of connecting buckles are arranged in the middle of the central rope, and the diameter of the central rope circular ring is larger than that of the restraint strap circular ring, so that the central rope circular ring is separated from the restraint strap circular ring; the constant-force ropes bind the central rope circular ring and the connecting buckles arranged at the opposite ends to form constraint, and under the action of external force, the first constant-force rope, the second constant-force rope and the weak-force rope are sequentially released from constraint to be completely unfolded. The system is light in weight, parachute opening impact force can be reduced under high-speed parachute opening, and meanwhile the requirement for landing safety after full-area unfolding is met.
本发明提供了一种降落伞开伞控制系统,包括伞衣和伞绳,伞衣包括中心伞衣部和约束伞衣部,该系统还包括中心绳,中心绳约束带、定力绳、中心绳圆环,约束伞衣部使用弱强力绳,中心绳约束带一端与中心伞衣部顶端连接,另一端设置有约束带圆环,中心绳一端设置中心绳圆环,另一端穿过约束带圆环与待投放物品连接,中部设置有多个连接扣,中心绳圆环比约束带圆环直径大,使中心绳圆环与约束带圆环分开,定力绳将中心绳圆环与相对端设置的连接扣捆扎形成约束,在外力作用下,定力绳一、定力绳二及弱强力绳依次解除约束伞衣完全展开。该系统重量轻,能够满足高速开伞下减小开伞冲击力,同时全面积展开后满足着陆安全性的要求。
