The transmission device of flapping and torsion combined motion of bionic flapping wing for micro air vehicle

Abstract

The invention discloses a transmission device for combined movement of bionic flapping wings flapping and torsion for a micro-aircraft, belonging to the field of aircraft design. The invention includes a support rod, a transmission mechanism and a flapping wing main structure. The support rod is arranged vertically, its bottom is fixedly connected to the fuselage of the micro-aircraft, and its middle and top are respectively connected with the transmission mechanism and the main beam of the flapping wing. The transmission mechanism includes an upper sleeve, a lower sleeve, a drive rod, a Γ-shaped connecting rod and a limit rope; the main structure of the flapping wing includes the main beam of the flapping wing, the outer beam of the flapping wing, the main rib of the flapping wing, the sub-beam of the flapping wing and the wing membrane. The technical problems that can be solved by the present invention are: (1) effectively reduce the resistance when the wing is shot up while ensuring that the lift force is at the maximum value; (2) the flapping wing can be adjusted by adjusting the length of the limit rope; The twisting angle has the advantages of simple and convenient operation; (3) The resistance in the up-shooting stage is reduced, and the resistance in the down-shooting stage is not significantly different from that of traditional flapping wings, which has the advantage of high energy utilization.

Description

technical field [0001] The invention relates to a transmission device for combined movement of bionic flapping wings flapping and torsion for micro-aircraft, and belongs to the field of aircraft design. Background technique [0002] The micro air vehicle is small in size and easy to carry, and has good maneuverability and concealment. Therefore, MAVs are suitable for completing tasks such as exploration, reconnaissance, and rescue in narrow spaces and harsh environments. It is precisely because of the application requirements and vacancies of micro air vehicles under special conditions that micro air vehicles have become a research hotspot in the field of aviation in the past two decades. wing aircraft. These three types of aircraft have their own advantages and disadvantages. To put it simply, fixed-wing aircraft has the traditional advantages of high-speed flight, but it is difficult to achieve hovering or vertical take-off and landing; rotorcraft can achieve vertical ta...

Problems solved by technology

These three types of aircraft have their own advantages and disadvantages. To put it simply, fixed-wing aircraft has the traditional advantages of high-speed flight, but it is difficult to achieve hovering or vertical take-off and landing; The torque leads to a more complex structure, and there are also disadvantages of low aerodynamic efficiency at low Reynolds numbers
