Foldable wind-resistant flapping wing of flapping-wing micro air vehicle

Abstract

The invention discloses a foldable wind-resistant flapping wing of a flapping-wing micro air vehicle. The foldable wind-resistant flapping wing comprises a wing base, a plurality of wing veins, a flexible pipe, a first elastic hinge, a V-shaped elastic piece, a ring buckle, a wing film, a cylindrical sliding block and a second elastic hinge, wherein the flapping wing is driven by the wing veins to unfold under the action of liquid pressure; at the same time, the cylindrical sliding block in the flexible pipe also starts to move towards the V-shaped elastic piece under the action of hydraulic pressure; finally, when the cylindrical sliding block moves to the tail end of the flexible pipe, the ring buckle on the sliding block is just locked with the V-shaped elastic piece; and a triangular structure is formed by a first wing vein, a second wing vein and the flexible pipe, so that the foldable wind-resistant flapping wing has good stability, the foldable flapping-wing type micro air vehicle can resist the pressure of strong air flow in flight, and the wind resistance effect of the wing of the foldable flapping-wing type micro air vehicle is improved. After liquid in a liquid chamber is pumped out, the ring buckle is separated from the V-shaped elastic piece, so that the formed triangular structure is removed, and the wing veins are folded under the pulling of the elastic hinges.

Description

technical field [0001] The invention refers to a wing of a flapping-wing micro-aircraft, in particular a foldable flapping wing with high wind resistance performance is designed. Background technique [0002] Micro air vehicle is called MAV (Micro Air Vehicle) for short. It is different from the traditional concept of aircraft. It is characterized by small size, light weight, easy to carry, and good concealment. its unique advantages. [0003] In the study of flapping-wing micro-aircraft, the foldable flapping-wing micro-aircraft has a good application prospect. On the one hand, when performing tasks such as low-altitude reconnaissance and complex terrain surveys, you will encounter narrow passages or spaces where straight wings cannot pass. However, this foldable flapping-wing micro-aircraft can reduce its size after folding and use its crawling function After completing obstacle surmounting, surveying, etc., when the space conditions permit, the folded wings can be unfol...

Problems solved by technology

[0004] However, there are still some problems in the research and development of foldable flapping wing micro-aircraft. For example, due to the existence of its flapping wing folding mechanism, its flapping wing cannot become a stable whole when flying in the wind. When disturbed by interference, its foldable wings may bend or even fail to maintain the airfoil and its correct flight attitude. Therefore, achieving wind resistance stability is an urgent problem to be solved in the design process of foldable flapping wing micro-aircraft
