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
At the same time, most of the current flapping-wing aircraft cannot achieve vertical take-off and landing and hovering in the air, and their flexibility and maneuverability are not good enough

Description

technical field [0001] The invention relates to the field of movable wing aircraft and flying robots, in particular to a continuous winged device with variable windward area and variable inclination angle driving energy adjustable for unmanned aerial vehicles. 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 o...
