A main body of the complete lifesaving parachute canopy is composed of a special-shaped parachute canopy piece, and the complete lifesaving parachute canopy is provided with a parachute top hole structure, a circumferential seam structure and an air blowing pocket structure. The special-shaped canopy piece is in a streamline shape with the thick middle and the two ends recovered, and the single-side section of the canopy is in a wing-like shape after the canopy is inflated. The umbrella top hole structure forms a top hole in the top of the canopy, and the top hole can be self-adaptively opened under the condition of high speed and can be self-adaptively shrunk after the speed is reduced; the circumferential seam structure is distributed in the middle of the canopy, an opening is formed in the canopy, and the opening can be self-adaptively opened under the condition of high speed and can be self-adaptively closed after the speed is reduced; the air blowing pocket structure is distributed on the upper portion of the canopy, a pocket opening is formed in the canopy, and the pocket opening can be opened to be inflated when the canopy is straightened. The parachute canopy of the escape parachute has a high aerodynamic resistance coefficient and a load shedding function under the condition of high-speed parachute opening, has a good straightening parachute opening procedure, and is suitable for lifesaving of a whole machine.
本发明公开一种整机救生伞伞衣,其主体由异形伞衣幅组成,具有伞顶孔结构、圆周缝结构和鼓风兜结构;异形伞衣幅采用中间粗、两端往回收的流线形,伞衣充气完成后单边截面为类机翼形;伞顶孔结构在伞衣顶部形成顶孔,其顶孔在大速度情况下能自适应张开、在速度变小后能自适应缩小;圆周缝结构分布在伞衣中部,在伞衣上形成开口,其开口能在大速度情况下自适应张开、在速度变小后能自适应闭合;鼓风兜结构分布在伞衣上部,在伞衣上形成兜口,其兜口能在伞衣拉直阶段打开充气。该救生伞伞衣具备高气动阻力系数、大速度开伞情况下减载功能、良好的拉直开伞程序,适用于整机救生。
