A connection structure of negative pressure folding wings

Abstract

The invention relates to a connection structure of a negative pressure folding wing, which belongs to the technical field of aircraft. It includes the wing made of rigid foam blocks, the nacelle, the fiber membrane wrapped outside the wing, and the connecting structure between the wing and the fuselage. There are holes in the hard foam block, and the elastic telescopic tube runs through it; the connection mechanism is composed of a curved slideway in the cabin, a metal mesh, and a claw hook. The metal mesh is connected to the hard foam block, and the claw hook is connected to the metal mesh. The claw hook can slide on the curved slide in the cabin. When the wing is vacuumed, the elastic telescopic tube shrinks, the hook moves on the slideway, and the wing unfolds; when the wing is folded, the hook can slide down naturally. The invention provides a connection structure between the wing and the cabin, which can effectively avoid the swing when the wing is unfolded and folded, quickly vacuumize the wing, and facilitate the unfolding of the wing.

Description

technical field [0001] The invention belongs to the technical field of aircraft, and in particular relates to a connection structure of a negative pressure folding wing. Background technique [0002] With the development of aircraft technology, there are more and more ways to fold the wings. Some folding wings adopt mechanical folding, which not only increases the weight, but also slows down the unfolding speed. At present, a negative pressure folding wing is proposed, which has the advantage of light weight , the deployment speed is fast, the cost is low, the reliability is good, and the occupied space is greatly saved, but there are still some problems, such as the connecting part of the wing and the fuselage, the previous connection is to fix the wing and the fuselage through the connecting mechanism , such as the use of nuts and screws to match the fastening method, which makes the assembly and disassembly process longer, thereby reducing the disassembly efficiency, and ...

Problems solved by technology

[0002] With the development of aircraft technology, there are more and more ways to fold the wings. Some folding wings adopt mechanical folding, which not only increases the weight, but also slows down the unfolding speed. At present, a negative pressure folding wing is proposed, which has the advantage of light weight , the deployment speed is fast, the cost is low, the reliability is good, and the occupied space is greatly saved, but there are still some problems, such as the connecting part of the wing and the fuselage, the previous connection is to fix the wing and the fuselage through the connecting mechanism , such as the use of nuts and screws to match the fastening method, which makes the assembly and disassembly process longer, thereby reducing the disassembly efficiency, and also uses other mechanisms to realize the connection between the wing and the fuselage, but for this negative pressure folding Wing, using the previous connection method, its structure is relatively complicated, and the cost is relatively high

In addition, when the wings are unfolded or folded, the swing of the wings and the rapid vacuuming are more serious problems.
