ABSTRACT:
The parachute having a canopy composed of a plurality of radially arranged asymmetrical polygonal panels of the same shape, with, each panel being sewn only partially to its adjacent panel so that, in the fully deployed state, a plurality of air exit nozzles are formed in the carrying zone section of the parachute in the unsewn regions with the nozzles all acting in the same circumferential direction. The effect of each air exit nozzle is improved and stabilized with respect to guiding the flow of air in the tangential direction in that a trapezoidal area is attached to the edge or side of each panel in the unsewn region so as to overlap the adjacent panel. In addition, each panel is preferably provided with a horizontal or concentrically extending stabilization slit which is disposed in the transition region between the carrying zone section and the guide zone section of the canopy.
