Abstract
In a parachute having a cap made of elongate, radially arranged cloth panels (6, 7) which are sewn together along their longitudinal edges, with the parachute being intended to rotate about its center axis during its descent, it is difficult to attach nozzle openings which direct the outgoing air in a tangential direction. A particularly simple parachute cap results if the cloth panels (6, 7) are cut asymmetrically in such a manner that they have side edges of different lengths and partial sections of the cloth panels, in their longitudinal extent, are left unsewn so as to form nozzle-shaped air exit openings (9) having curved edge regions (8). The cut piece of cloth may have the shape of a trapezoid with a scalene triangle attached to its base. Weights (12) may be attached in the edge region of the air exit openings (see attached Figure).
Claims12
In a rotating parachute having a cap of elongate, radially arranged cloth panels which are sewn together along their longitudinal sides, and a plurality of air exit openings provided in said cap for imparting a rotational torque to said cap, the improvement wherein:
- at least a majority of the individual panels of cloth are cut asymmetrically such that their side edges have different lengths;
- said majority of cloth panels are similarly oriented in said cap;
- the longer longitudinally extending side edge of each of said majority of panels is adjacent a shorter longitudinally extending side edge of the adjacent panel;
- in partial sections between the ends of their longitudinal extent, the longer longitudinally extending side edges of said majority of panels of cloth are left unsewn;
- said unsewn sections of said longer longitudinally extending sides of said panels form said air exit openings which are all oriented to provide a torque in the same rotational direction;
- and said air exit openings are nozzle-shaped with curved edge regions when said cap is inflated.
In a rotating parachute having a cap of elongate, radially arranged cloth panels which are sewn together along their longitudinal sides, the improvement wherein:
- all of the individual panels of cloth are cut asymmetrically such that their side edges have different lengths, with the straight line distance between the ends of said panels along their longer longitudinally extending side being longer than the straight line distance between the ends of said panels along their shorter longitudinally extending side;
- said panels are sewn together so that the shorter longitudinal side edge of one panel is sewn to the longer side edge of the adjacent panel;
- in partial sections between the ends of their longitudinal extend, the longitudinally extending side edges of said panels of cloth are left unsewn;
- and said unsewn sections of the longer longitudinally extending sides of said panels form nozzle-shaped air exit openings having curved edge regions when said cap is inflated.
