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 type aircrafts and flying robots, in particular to a rotary vane based synchronous swing type double-flapping-wing aircraft which comprises two flapping wings, two swing shafts, two connecting pieces, two first speed reducers, two stepping motors, a transmission mechanism, a second speed reducer, an electromotor and a fuselage ring, wherein the two swing shafts are symmetrically mounted and fixed on the two sides of the fuselage ring in the horizontal direction; the two connecting pieces are connected onto the two swing shafts separately androtate relatively; the two flapping wings are connected onto the two connecting pieces separately and can rotate relatively; each of the flapping wings comprises a flapping wing frame and a rotatablevane mounted in the flapping wing frame; a torsional spring for resetting the vane is further arranged in the flapping wing frame; the transmission mechanism is connected onto the two connecting pieces; after the second speed reducer reduces the speed of the electromotor, the electromotor drives the transmission mechanism to move, so that the two connecting pieces synchronously swing up and down;and after the two first speed reducers reduce the speed of the two stepping motors, the two stepping motors drive the two flapping wings to rotate separately.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a synchronously swinging double flapping-wing aircraft based on 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 that of the propeller. ...
