Abstract
A rotary parachute includes a canopy having an apex and comprised of triangular, sewn-together fabric segments each having a base edge along an outer circumference of the canopy, a tip opposite the base edge and longitudinal edges on either side of said tip with seams connecting together the adjacent longitudinal edges of adjacent segments and rotation slits existing in regions of the respective seams. The tip of each segment is offset laterally from the apex of the canopy to form an apex opening in the canopy having a shape of a regular polygon and the base edges are offset from one another so that each segment has a circumferentially projecting tip.
