Flapping-wing micro air vehicle based on fan driving

Abstract

The invention discloses a flapping-wing micro air vehicle based on fan driving. The flapping-wing micro air vehicle is characterized in that a fan driver is combined with hinged connecting rod mechanisms, is arranged in the hinged connecting rod mechanisms and is fixedly connected with the inner-side end surfaces of the hinged connecting rod mechanisms; the hinged connecting rod mechanisms at two sides are symmetrically arranged; a driving connecting rod is fixed on the free end of the fan driver, and a pushing rod is connected with the driving connecting rod; one end of a control rod is connected with the pushing rod, the other end of the control rod is fixedly connected with the front edges of wings, and the control rod is connected with the hinged connecting rod mechanisms at the side surfaces of the fan driver; a torsion control rod is connected with the hinged connecting rod mechanisms at the side surfaces of the fan driver; one end of the torsion control rod is in contact with a wear-resistant cushion block stuck at the end part of the pushing rod, and the other end of the torsion control rod is connected with the rear edges of the wings; and the up-down vibration of the fan driving mechanism is transferred and amplified under a loading alternating voltage, and the wings are driven by the action of flexible hinges to realize up-down flapping and torsion. The flapping-wing micro air vehicle disclosed by the invention has the advantages that the structure is simple, the processing is convenient and the driving control is simple.

Description

technical field [0001] The invention relates to a flapping-wing bionic aircraft, in particular to a micro-flapping-wing aircraft driven by a fan, belonging to the field of flapping-wing bionic aircraft. Background technique [0002] Micro-flapping-wing aircraft imitates the way of biological flight, and uses the unsteady flow field generated by flapping wings to achieve flight.
