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.
Claims18
Device for accelerating the operation of aviation apparatus, constructed as a gliding parachute formed by a plurality of air chambers connected at their sides, these air chambers being typically open at their one end and closed at their other end, the aviation apparatus being provided, with a plurality of shrouds for carrying a load, said shrouds being attached to said aviation apparatus, characterized in that the device (1) is formed as a hose (tube)-shaped air space (4) and in that this air space is equipped with filling and isolating valves (11) and, in the operative condition of the aviation apparatus is filled with air at high pressure;
- wherein the air chambers (20) are formed with the air spaces (4) at least in their top sections;
- wherein the hose-shaped (tubular) air space (4) forms an airfoil section extending over the full length of the particular air chamber (20) and in that this airfoil section is provided on both sides of an air chamber.
Device for accelerating the operation of aviation apparatus, the aviation apparatus being provided, with a hem, in particular, at its side or end facing the air mass to be entrapped, and equipped with a plurality of shrouds for carrying a load, said shrouds being attached and guided on said hem, characterized in that the device (1) is formed as a hose (tube)-shaped air spaced (4) and provided along at least part of the circumference of the hem and in that this air space is equipped with filling and isolating valves (11) and, in the operative condition of the aviation is filled with air at high pressure;
- wherein at least one opening restrictor (5) is provided between the load (16) and the aviation (canopy 2, square parachute 19) for the shrouds (3) and in that this opening restrictor permits the radial spreading of the shrouds only when a present g-load (decceleration force) is reached;
- wherein the opening restrictor (5) is formed by a ring-shaped collar (27) attached to one shroud (3) and embracing the other shrouds as well as a pin (31) capable of being withdrawn from holes (32) in the collar;
- wherein the opening restrictor (5) is formed by a spacer (28) provided on one shroud (3) as well as spring means (29 rubber band, spiral spring) arranged parallel to the latter as well as a locking pin (33) releasing (on withdrawal) the spring tension and in that this locking pin (33) is fastened to the same shroud (3) as the spacer (28) and is released from its lock as this shroud is extended.
