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

Abstract

The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a variable-inclination swing double flapping-wing unmanned aerial vehicle equipped with rotatable wings. Including flapping wings, swing shafts, connectors, first reducer, stepping motor, transmission mechanism, second reducer, motor and fuselage frame, two horizontal swing axes are installed and fixed symmetrically on both sides of the fuselage frame The two connecting pieces are respectively connected to the two swing shafts and rotate relatively, the two flapping wings are respectively connected to the two connecting pieces and can rotate relatively, the flapping wings include a flapping wing frame, and a movable For the rotating wings, torsion springs are also provided in the flapping wing frame for the reset of the wings. The two sets of transmission mechanisms are respectively hinged on the two connecting parts. The movement of the mechanism makes the two connecting parts swing up and down, and the two stepping motors arranged on the connecting parts respectively drive the two flapping wings to rotate after being decelerated by the two first reducers.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a variable-inclination swing double flapping-wing unmanned aerial vehicle equipped with rotatable wings. 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 flapping wing is higher than t...
