ABSTRACT:
Device for accelerating the opening and/or the extension of aviation devices, such as canopy, square or gliding parachutes, among others, has an air space (4) at the base (7) and along the circumference of the canopy (2). The air space (4) has for example the form of a hose or of an air-impervious hem which is under high air pressure in operative conditions, so that when the wrapper is opened this air space stretches out in a very short time and the aviation device opens after a fall of only 20-30 m.
