Folding wing with flat folding extension wing

Abstract

The invention discloses a folding wing with a flat folding extension wing and belongs to the aviation field. The folding wing is mainly formed by combining the flat folding extension wing with an existing triangular folding wing, and then the folding wing with the flat folding extension wing of an integral structure is formed. The flat folding extension wing is synchronously folded or unfolded along with a main wing, and the wing is small in occupied area after being folded. After the wing is unfolded, a fixed wing body formed by combining the triangular folding wing with the flat wing is formed, and lifting force is provided for an aircraft. According to the folding wing, the airfoil of the wing is improved, the aspect ratio of the wing is increased, the efficiency of the wing in the low-speed flight state of the aircraft is improved, and the wing is more suitable for use on the lightweight aircraft. By installing an auxiliary wing on the flat folding extension wing, the condition that a folding wing in the prior art does not have a wing control surface is changed; and by adjusting the auxiliary wing, the shape of the wing can be changed, so that the flight state of the aircraft is controlled.

Description

[0001] Field of invention: [0002] The title of the present invention is: "folding wing with straight folding extension wing" belongs to the field of aviation. Background technique: [0003] The existing technology is: a folding wing composed of patent No. 201620324195.X, patent No. 201621063844.1, and patent No. 201910263631.5, which has the performance of a fixed-wing wing that can be completely folded and unfolded, and can be widely used in various Type Small and light manned and unmanned aerial vehicles. [0004] The existing foldable wing is mainly composed of foldable multiple triangular support frameworks, slide rails, skin support ribs, airbag inflatable skin, and wing action device to form a foldable and unfoldable triangular fixed-wing wing. [0005] The technical defect of prior art is: [0006] 1. The aspect ratio of the triangular wing is low, and the aerodynamic efficiency is not as high as that of the straight wing at low speed. [0007] 2. The wing has no a...
