Straight foldable wing of flapping-wing aircraft

Abstract

A straight foldable wing of a flapping-wing aircraft belonging to the field of flapping-wing aircraft technology comprises a coating and wing frameworks. The wing frameworks are distributed symmetrically; the coating appearing as bat is adhered on the wing frameworks, wherein the wing frameworks respectively comprise a torsion spring structure, rod pieces and link rods; one end of the torsion spring structure is divided into five sections: a front arm section, an upper arm section, a body side section, a thigh section and a shank section; four bends, i.e. an elbow part, a shoulder part, a crotch part and a knee part, are arranged among the five sections, wherein the elbow part is the spring part of the torsion spring structure; the bending part between a wrist part and the shoulder part is the elbow part; the connection between the elbow part and the wrist is the front arm section; the connection between the elbow part and the shoulder part is the upper arm section; and the elbow part is lower than the shoulder part and the elbow part. The straight foldable wing has the beneficial effects of obtaining the foldable feature of foldable wing while preserving features of prior straight-wing, and realizing turned flying of the flapping-wing aircraft by changing area of wing and in virtue of area difference.

Description

technical field [0001] The invention belongs to the technical field of flapping-wing aircraft, in particular to a straight foldable wing of the flapping-wing aircraft. Background technique [0002] Flapping-Wing Micro Air Vehicle (FMAV) is a new type of aircraft that imitates the flight of animals. Compared with fixed-wing and rotary-wing aircraft, its main feature is that it can integrate the lifting, hovering and propulsion functions into one One piece, without propeller or jet device, it has strong maneuverability and flexibility. To realize these functions, the executive mechanism—the flapping wing plays a key role, so designing and making the flapping wing plays a very important role in the field of flapping aircraft research. [0003] At present, due to the simple design and manufacture of the straight wing, it is widely used in the field of flapping wing aircraft. The common wing of the flapping wing aircraft is a straight wing, and its structure is as follows: figu...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the complex structure of the existing wing and the inability to realize the lateral twisting and folding of the wing, the invention provides a straight foldable wing of a flapping wing aircraft, which realizes the bionic feature of flying animals relying on wing turning. It can rely on the driving mechanism to achieve horizontal folding, and by changing the wing area on one side of the fuselage respectively, the turning flight of the flapping wing aircraft can be realized by relying on the area difference on both sides
