The invention discloses a parachute canopy folding structure, a parachute, a landing system and an unmanned aerial vehicle. The parachute canopy comprises a center area and a folding area, and the folding area wraps the center area. The plurality of zigzag folding lines are diffused to the edge of the canopy on the folding area by taking the central area as the center, and each subarea canopy is folded into accordion folds by the folding lines, so that the canopy is folded into a plurality of accordion fold columns by taking the boundaries as axes; and the longitudinal length of the accordionfold columns is shortened by folding the accordion pleats. The parachute comprises a parachute box, a gas trigger, a parachute canopy and a parachute mooring rope, the canopy folding structure is installed outside the gas trigger, and the gas outlet of the gas trigger right faces the central area of the canopy. The landing system comprising the parachute is used for executing parachute opening ofthe parachute and power failure of the unmanned aerial vehicle. The present invention provides the unmanned aerial vehicle; and the parachute is fixed to an upper cover of the unmanned aerial vehicle,and the parachute cable penetrates through the parachute box to be tied to the arms.
本发明公开了降落伞伞衣折叠结构、降落伞、降落系统、无人机;伞衣包括中心区域和折叠区域,折叠区域包在中心区域外;多条“回”字行折线以中心区域为中心、在折叠区域上向伞衣边缘扩散,折线将每一分区域伞衣折叠成为风琴褶,使伞衣折叠为多条以分界线为轴的风琴褶柱;风琴褶柱再按风琴褶折叠缩短其纵向长度。其降落伞,包括伞盒、气体触发器、伞衣、伞缆绳;伞衣折叠结构安装在气体触发器外,其中气体触发器出气口正对伞衣中心区域。包括上述降落伞的降落系统,用于执行降落伞开伞和无人机停电。无人机;降落伞固定在无人机上盖,伞缆绳穿过伞盒系在机臂上。
