Problems solved by technology

The main reason for the overall low efficiency of flapping wing aircraft is that most of the current research simply imitates the shape and flapping motion of the wings of birds or insects, but it is difficult to realize the use of the wing's own posture and structure in the process of flapping wings of flying creatures. The change of air resistance reduces air resistance and generates unsteady aerodynamic force, and the resulting low aerodynamic efficiency seriously restricts the popularization and application of flapping-wing aircraft

The rotatable fins in the flapping wing frame are also provided with torsion springs for the reset of the flapping wing frame. Compared with the prior art, the present invention has the characteristics of small reset stroke resistance, large and stable working stroke thrust, high aerodynamic efficiency, simultaneous adjustment of lift and thrust, simple device structure, and convenient manufacture, and can be widely used in low Reynolds number All kinds of small aircraft and drones flying.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a wing-adaptive rotating and swinging flapping wing with variable inclination and a method thereof for an unmanned aerial vehicle. Background technique [0002] There are three flight types of aircraft flying: fixed wing, rotary wing and flapping wing. Among them, flapping wing flight is the flying mode adopted by flying creatures in nature. It mainly uses the up and down flapping of the wings to generate lift and thrust at the same time. , hovering and propulsion functions are based on one body, and at the same time have strong maneuverability and flexibility, and are more suitable for flying around obstacles. For small-sized and low-speed aircraft flying under low Reynolds numbers, the unsteady lift generated by the flapping wing is much greater than the constant lift of the fixed wing; from the perspective of thrust, the propulsion efficiency of the flap...
