The invention discloses a regular octagonal umbrella with high stability. The plane shape of the parachute canopy is a regular octagon, the structural opening seams are additionally arranged on the side faces of the parachute, and the eight parachute canopy structural opening seams are designed, so that disordered airflow in the parachute can flow out more easily, and stability is improved. The high-stability umbrella-shaped structure is good in air permeability, in the working process, the swing angle amplitude is reduced, and the stability is improved; the maximum parachute opening dynamic load can be effectively reduced, the stability and the wind resistance are improved, and the landing speed and damage are reduced.
本发明公开了一种高稳定性正八边形伞型。伞衣平面形状是正八边形,在伞的侧面增加结构开口缝,本发明设计了八个伞衣结构开口缝,使降落伞内的紊乱气流更易流出,用以增加稳定性。该高稳定性伞型结构透气量好,在工作过程中,减小了摆动角幅度,提高了稳定性;能够有效的降低最大开伞动载,提高稳定性和抗风性,减少着陆速度和损伤。
