A dragonfly-like micro-aircraft with double flapping wings

Abstract

The invention belongs to the technical field of bionic micro-aircraft, and provides a dragonfly-like double-flapping-wing micro-aircraft, which includes a body shell, a body head, a body tail, and four wings symmetrically arranged on both sides of the body shell, each of which The wings are all rotatably connected to the body shell through universal ball bearings, and four control mechanisms for controlling the flapping of the wings and changing the angle of attack of the wings are arranged in the body shell, and each of the wings One end of each passes through the body shell and is connected with its corresponding control mechanism. The micro air vehicle highly simulates the aerodynamic layout design of dragonfly wings. It adopts a double-row layout scheme, which can use the favorable aerodynamic interference between the front and rear wings to achieve high aerodynamic efficiency. Each wing can be individually controlled to achieve individual flapping and pitching. , and then realize a variety of maneuvers, improve aerodynamic performance and maneuverability.

Description

technical field [0001] The invention relates to the technical field of bionic micro-aircraft, in particular to a dragonfly-like micro-aircraft with double flapping wings. Background technique [0002] Dragonfly is one of the few insects that can glide and fly. It has two pairs of wings with large aspect ratio. Through the independent control of the four wings, it can realize complex maneuvers such as rapid take-off, acceleration and hovering. The main reason is that the dragonfly's four wings can reasonably control the flow of the surrounding air according to its own movement needs when flapping and flying, and then generate the lift and thrust required for flight. When the lift generated is enough to support the weight of the body and balance is reached, hovering flight can be realized. [0003] In order to study the flight mechanism of the dragonfly's wings, many people have used the principle of bionics to design and manufacture a micro-aircraft that can simulate the fla...

Problems solved by technology

However, most of the existing micro-aircraft are still rotors or single flapping wing aircraft, and compared with the high maneuverability of dragonflies, there is still a big gap.

[0004] In the invention patent application document with the publication number CN 108438220 A, a multi-degree-of-freedom imitation dragonfly flapping wing aircraft and its control method are disclosed. The aircraft adopts the form of four-drive flapping wings, which can realize pitch, yaw, and hover However, the aircraft mainly focuses on flight control, the structure is relatively complex, and the manufacturing and assembly precision requirements are high, so it is difficult to achieve miniaturization

[0005] In addition, since the real dragonfly has a long fuselage, the auxiliary flight control can be realized through the movement of the fuselage, but the structure of the aircraft is very different from the real dragonfly, and the degree of bionicity is not high, so it cannot be used to simulate the flapping flight of dragonfly wings Research
