Problems solved by technology

However, during the recycling and folding process of the parafoil, the stacking pressure will deform the reinforcing sheet or cause irreversible creases. After repeated use, the reinforcing sheet may be damaged or fail, which will affect the performance of the parafoil
The process of repairing and replacing the reinforcement sheet is complicated, and the strength of the parafoil will be damaged during the repair process
In view of the above reasons, the plastic reinforcement sheet can only be sewn on the lower part of the front edge, and only plays a part of the support and reinforcement function, and the effect of forming and recycling is not ideal

Abstract

The invention discloses a front air chamber automatically-forming punched parafoil. A plurality of ribs are arranged between an upper wing surface and a lower surface of the parafoil, one ends, along a front opening, of the plurality of ribs of front opening parts at two sides of the parafoil are provided with sleeves with the length identical to that of the ribs along the outer contour, a flexible wire-shaped structure is inserted into each sleeve, two ends of the sleeve are sealed finally, the shape of the ribs is braced by using the elasticity of the flexible wire-shaped structures, and the diameter of each flexible wire-shaped structure is 4mm to 6mm. A parafoil can be automatically formed by a front air chamber, so that the collapse problem of the front opening of a canopy is solved, and the parafoil can rapidly take off and can fly safely.

Description

technical field [0001] The invention belongs to the field of flying parafoils, and more specifically relates to a stamping parafoil with a leading edge air chamber automatically formed. Background technique [0002] The stamping parafoil is a safe and reliable sports umbrella with good gliding and maneuverability. It is widely used in sports competitions and flying hobbies, and replaces the round slit umbrella as the only type of sports competition umbrella. With the wide application of ram parafoil in sports competitions, its structure and parachute opening control are constantly improved. Therefore, ram parafoil has become the only choice for high-performance controllable paragliders today. [0003] Before the parafoil takes off, it is unfolded, the air inlet is facing upwards, and the parafoil is paved in a horseshoe shape. In addition to strong headwind, in all other wind conditions can be carried out. Before takeoff, the pilot should be in the middle of the parafoil ...
