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.
