Airbag inflatable skin of folding wing

Abstract

The invention discloses an airbag inflatable skin of a folding wing, which is used for upper and lower surface skins of the folding wing, and belongs to the field of aviation. The airbag inflatable skin of the folding wing covers an outer surface of the folding wing so as to form the wing outer surface skin, and under pulling of a wing supporting framework (1) and skin supporting ribs (3), foldingor unfolding can be achieved. The inflatable skin is characterized in that the wing skin between the skin supporting ribs (3) is a double-layer airbag inflatable skin, and the airbag inflatable skintaking the wing supporting framework (1) and the skin supporting ribs (3) as frameworks forms an outer surface skin of the wing so that better tightness and hardness are achieved.

Description

[0001] Field of invention: [0002] The title of the invention is: "the airbag inflatable skin of the folding wing" is used for the upper and lower surface skins of the folding wing, and belongs to the field of aviation. Background technique: [0003] The existing technology is: the folding wing shown by the patent number: 201620324195.X and the patent number: 201621063844.1, which can be fully folded and fully unfolded, and can be widely used in various types of small and light manned or unmanned aircraft. [0004] The upper and lower surface skins of the existing folding wings are made of flexible and foldable materials, which are connected to the upper and lower surfaces of the wing leading edge beam and the skin support ribs to form the outer surface of the wing. When the wings are unfolded, the wing expansion device will The force is applied to the wing support frame composed of triangular trusses, so that one edge slides along the slide rail, changing the shape and area...

AI Technical Summary

Problems solved by technology

[0005] The defect of the prior art is that: the stretching force of the wing supporting frame is applied to the skin of the wing surface to make it unfold and tensioned. The greater the capacity, the greater the force required to expand the supporting frame, and the greater the force the supporting frame bears, which will result in the need to strengthen the structural strength of the supporting frame and increase the output power of the wing expansion device, which will cause Increased weight of the wing structure and increased energy consumption

[0006] The existing technology is feasible for wings with a smaller wingspan, but for wings with a larger wingspan, it is necessary to use the existing technology to fully stretch the surface skin tightly enough by the stretching effect of the supporting skeleton. difficult
