Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of airborne airdrop, and in particular to a parachute main parachute canopy device suitable for double persons. Background Art
[0002] The parafoil is a lightweight, efficient, non-powered sports equipment used for gliding flight. The parafoil is usually composed of a canopy, a canopy cover, a closing cloth, a parachute rope, a control belt and a control rope. The main function of the canopy cover is to prevent the canopy bottom edge from being inflated prematurely, resulting in uneven force, fabric damage, entanglement and hooking, etc. At the same time, the canopy cover should also ensure that the canopy and the parachute rope have a good straightening process to avoid or reduce the canopy whipping the parachute rope.
[0003] At present, most canopy covers manufactured in China are long-tube canopy covers. The long-tube canopy cover is shaped like a closed sleeve, which can hold all the folded canopy. Fabric loops or rubber rope loops are sewn on the canopy cover for the parachute ropes to pass through. There is a bottom cover cloth on the canopy cover, and the bottom cover cloth has multiple holes. A bunch of parachute ropes are inserted into the detachable rubber rope loops passing through the holes to lock the bottom cover cloth and prevent the canopy from inflating prematurely.
[0004] The disadvantage of the long-tube canopy cover is that when the system is straightened at a high speed, the effect of inertia will cause the canopy to move downward along the canopy cover, causing the canopy to accumulate at the bottom of the canopy cover. When the canopy cover is removed, the canopy falls out in a ball, causing whipping. In extreme cases, the rubber ring may be broken before the parachute rope is completely straightened, and the canopy falls out and interferes with the unstraightened parachute rope, affecting the safety of parachuting. This phenomenon is particularly obvious under high speed and strong inertia, so it is difficult to adapt to the requirements of high-altitude skydiving speed and large total weight. In addition, the long-tube canopy cover has a complex structure, high process difficulty, consumes a lot of materials, and has high production and inspection costs. Summary of the invention
[0005] The purpose of the invention is to provide a main parachute cover device for a wing parachute suitable for two persons.
[0006] The technical solution to achieve the purpose of the present invention is: a main parachute canopy cover device suitable for a double-person wing parachute, the main parachute canopy cover structure is a cloth-wrapped type, the main cloth of the main parachute canopy cover is rectangular, a middle reinforcement belt is sewn in the middle of the main cloth of the main parachute canopy cover, and it is sewn together with the side rib reinforcement belt of the main parachute canopy; peripheral reinforcement belts are sewn on the left and right sides and the bottom of the main cloth of the main parachute canopy cover, 3 to 8 holes are evenly opened on the peripheral reinforcement belt arranged on one side of the main cloth of the main parachute canopy cover, and a metal workpiece locking ring body is provided, and a plurality of short fixing belts are sewn on the other side, and the number and position of the short fixing belts and the locking ring body correspond one to one, and the short fixing belts can be put through a latex ring, and a long fixing belt is sewn on the peripheral reinforcement belt at the bottom of the main cloth of the main parachute canopy cover, with the middle reinforcement belt as the boundary, 2 to 6 latex rings can be put through the left and right sides of the long fixing belt, and the latex rings are arranged symmetrically with the middle reinforcement belt as the axis.
[0007] Furthermore, after the main parachute canopy is exhausted and folded into a strip, the umbrella rope and the part of the umbrella rope that exceeds the bottom edge of the umbrella canopy are folded back, and the folded main parachute canopy is wrapped with the umbrella canopy cover. When the umbrella rope is folded back, the bottom edge of the umbrella canopy is kept aligned with the lower edge of the umbrella canopy cover; the latex ring on the short fixing belt passes through the corresponding ring hole of the locking ring body and is blocked in turn with the umbrella rope. The latex ring at the bottom of the peripheral reinforcement belt does not pass through the locking ring body, and the umbrella rope is passed through the latex ring on the relatively arranged long fixing belt (5) in a zigzag shape to seal the bottom edge of the umbrella canopy.
[0008] Furthermore, the bottom of the air inlet at the leading edge of the main parachute canopy is completely sealed in the canopy cover through a latex ring on the bottom long fixing belt.
[0009] Compared with the prior art, the present invention has the following significant advantages: (1) It can effectively solve the problem of canopy accumulation under the inertia when it is straightened at a high speed, reduce the risk of canopy falling out in a ball, prevent the canopy rope from being entangled with the canopy, and improve the safety of opening the parachute. (2) It can effectively simplify the canopy cover structure, reduce the difficulty of the process, and facilitate use and inspection. BRIEF DESCRIPTION OF THE DRAWINGS
