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 flight robots, in particular to a synchronous swinging type rotary vane four-flapping-wing aircraft. The synchronous swinging type rotary vane four-flapping-wing aircraft comprises flapping wings, swinging shafts, connecting pieces, first speed reducers, stepping motors, a transmission mechanism, a second speed reducer, a motorand a machine body frame. The four horizontal-direction swinging shafts are symmetrically installed and fixed to the periphery of the machine body frame. The four connecting pieces are connected to the four swinging shafts and oppositely rotate. The four flapping wings are connected to the four connecting pieces correspondingly and can oppositely rotate. Each flapping wing comprises a flapping wing frame and a rotary vane arranged in the flapping wing frame, wherein a torsion spring is further arranged in the flapping wing frame for vane resetting. The transmission mechanism is connected to the two connecting pieces, and after the motor is decelerated through the second speed reducer, the transmission mechanism is driven to move, the four connecting pieces synchronously swing up and down,and the four stepping motors drive the four flapping wings to rotate after being decelerated through the two first speed reducers.

Description

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