ABSTRACT:
The gliding parachute which is closed at its leading edge comprises substantially in the zone of the highest aerodynamic impact pressure pressurizing air entry openings located in the lower parachute sheet, which openings lead to a stabilizing of the shape of the parachute comprising substantially an upper and a lower parachute sheet forming an air foil structure. In order to inflate this parachute during the starting phase, inflating air entry openings are located downstream of the pressurizing air entry openings, which inflating air openings are designed as check valves. This causes a faster and safer filling of the interior of the parachute by air.
