    • An annular spinning parachute is composed of an annular canopy symmetrical about an apex, suspension lines of substantially the same length and interconnected together at the canopy apex and extending radially outwardly therefrom across the canopy and downwardly therefrom for coupling to an object supported by the parachute, and centerlines interconnected with the suspension lines at the canopy apex and extending downwardly therefrom for coupling to the object supported by the parachute. The annular canopy includes fabric panels each having a generally trapezoidal shape defined by a pair of opposing inner and outer borders with the outer border being greater length than the inner border and a pair of opposing side borders of substantially the same length. The annular canopy also includes inner and outer lateral bands respectively extending along and connected to the inner and outer borders of the fabric panels so as to dispose the panels in circumferentially spaced relation with respect to one another upon inflation of the canopy. The inner and outer bands and spaced panels define a central opening in the canopy having thhe canopy apex at the center of the opening and a plurality of exhaust vents arranged in alternating relation with the panels between the side borders of adjacent pairs of the panels.
    • 环形旋转降落伞由围绕顶点对称的环形舱盖组成,悬挂线基本上相同的长度,并且在冠层顶端处互连在一起,并从其上径向向外延伸穿过冠层并向下延伸,用于联接到由降落伞支撑的物体, 以及与冠层顶点处的悬挂线相互连接并且向下延伸的中心线,用于联接到由降落伞支撑的物体。 环形顶盖包括各自具有由一对相对的内部和外部边界限定的大致梯形形状的织物面板,外部边界的长度大于内部边界的长度以及基本上相同长度的一对相对的侧边缘。 环形罩还包括分别沿着织物面板的内边界和外边缘延伸并连接到织物面板的内边缘和外边缘的内侧和外侧边带,以便在罩盖膨胀时将面板相对于彼此以周向间隔开的关系布置。 内部和外部带和间隔开的面板限定在顶盖中的中心开口,其具有位于开口中心处的顶盖顶点和与相邻面板对侧边缘之间的面板交替关系排列的多个排气口。
