Two-section type three-degree-of-freedom flapping wing aircraft

Abstract

The invention discloses a two-section type three-degree-of-freedom flapping wing aircraft comprising a body, inner flapping wings and outer flapping wings, a driving motor is arranged on the body, power is transmitted to two first transmission rods arranged side by side, the two inner flapping wings are arranged on the two sides of the body correspondingly, and each inner flapping wing comprises afirst inner wing supporting rod and a second inner wing supporting rod; each first inner wing supporting rod is driven to flap through a first inner wing flapping assembly arranged on the body, eachsecond inner wing supporting rod is driven to flap through a second inner wing flapping assembly arranged on the body, the two outer flapping wings are arranged on the two sides of the two inner flapping wings respectively, and the outer flapping wings comprise outer wing supporting rods. Each outer wing supporting rod achieves folding motion and torsion motion through folding torsion driving assemblies arranged on the first inner wing supporting rod and the second inner wing supporting rod, the inner flapping wing and the outer flapping wing can effectively achieve flapping, folding and torsion under the driving of only one driving motor, and the whole mechanism is smooth, stable and reliable in operation.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft, in particular to a two-stage three-degree-of-freedom flapping-wing aircraft. Background technique [0002] The flapping wing aircraft is an aircraft designed based on the principle of bionics and imitating the flight methods of flying creatures such as birds or insects. Studies have shown that the flapping-wing aircraft has a special high-lift generation mechanism, and has excellent flight capabilities under unsteady flow fields and low Reynolds numbers. Compared with traditional fixed-wing and rotary-wing aircraft, the flapping-wing aircraft has flexible maneuverability, high flight efficiency, With many advantages such as low energy consumption and good concealment, it can be widely used in various fields such as agriculture, military, security, disaster relief, and remote sensing. However, most of the existing flapping-wing aircraft use a single-degree-of-freedom flapping method, which p...
