The invention discloses a two-stage three-degree-of-freedom flapping wing aircraft, comprising a body, an inner flapping wing and an outer flapping wing. A drive motor is arranged on the body to transmit power to two first transmission rods arranged side by side, two The inner flapping wings are respectively arranged on both sides of the body, and the inner flapping wings include a first inner wing support rod and a second inner wing support rod, and each first inner wing support rod is driven by a first inner wing flapping assembly arranged on the body Flutter, each second inner wing support rod is driven to flutter by the second inner wing flapping assembly arranged on the body, two outer flapping wings are respectively arranged on both sides of the two inner flapping wings, and the outer flapping wings include outer wings Support rod, each outer wing support rod realizes folding motion and torsional motion through the folding and torsion drive components arranged on the first inner wing support rod and the second inner wing support rod, and only driven by one drive motor, the inner flapping wings and The outer flapping wings can effectively realize flapping, folding and twisting, and the whole mechanism runs smoothly, stable and reliable.
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] A flapping-wing vehicle is an aircraft designed based on the principle of bionics, imitating the flight mode of flying creatures such as birds or insects. Studies have shown that flapping-wing aircraft has a special high lift generating mechanism, and has excellent flight ability under unsteady flow field and low Reynolds number. Compared with traditional fixed-wing and rotary-wing aircraft, flapping-wing aircraft has flexible maneuverability, high flight efficiency, Low energy consumption, good concealment and many other advantages, can be widely used in agriculture, military, security, disaster relief, remote sensing and other fields. However, most of the existing flapping-wing aircraft use a single-degree-of-freedom flapping method, which produces small lift and thrust, resulting in...
