The invention discloses a ram-type parafoil and a delayed unfolding method, and relates to the field of ram-type parafoils. The ram parafoil comprises a parafoil body, a fixing box and a plurality of parafoil ropes with the two ends connected with the parafoil body and the fixing box respectively, and further comprises at least one pair of restraining ropes arranged at the two ends of the parafoil body respectively and a plurality of strong ropes which are broken when being pulled, and the bottoms of two restraining air chambers at the two ends of the parafoil body are connected with a plurality of restraining guide rings respectively. The bottom ends of each pair of restraint ropes are connected to the fixing box, the top ends of each pair of restraint ropes sequentially penetrate through the multiple restraint guide rings connected with the two restraint air chambers from inside to outside, and each strong rope is used for fixing a section of loose restraint rope to the two adjacent penetrating restraint guide rings. According to the ram-type parafoil and the delayed unfolding method, the unfolding speed of the ram-type parafoil can be delayed, the area of the ram-type parafoil is gradually expanded, and therefore the parachute opening impact force is reduced, and the strength of used materials and the use cost are reduced.
一种冲压翼伞及延时展开方法,涉及冲压翼伞领域。冲压翼伞包括翼伞本体、固定箱及多根两端分别连接翼伞本体和固定箱的伞绳,还包括至少一对分别设于翼伞本体两端的约束绳及多根受到拉力时断开的强力绳,翼伞本体两端的两个约束气室底部分别连接有多个约束导向环,每对约束绳的底端分别连接于固定箱,每对约束绳的顶端分别从内向外依次穿过两个约束气室连接的多个约束导向环,每根强力绳用于将一段松弛的约束绳固定于穿过的两个相邻约束导向环。本申请提供的冲压翼伞及延时展开方法能够延缓冲压翼伞的展开速度,使冲压翼伞的面积逐步展开,从而减小开伞冲击力,降低使用材料强度和使用成本。
