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 a double-synchronous-swing parallelogram-driven roller shutter type flapping-wing unmanned aerial vehicle. The unmanned aerial vehicle comprises flapping wings, swing shafts, connecting pieces, first speed reducers, driving motors, a transmission mechanism, second speed reducers, stepping motors, a fuselage frame, third speed reducers and a motor; the two swing shafts in the horizontal direction are symmetrically and fixedly mounted on the two sides of the fuselage frame, and the two connecting pieces are connected to the two swing shafts correspondingly and rotate relatively; the two flapping wings are connected to the two connecting pieces respectively and can rotate relatively, each flapping wing comprises a flapping wing frame and a roller blind mounted on the flapping wing frame, and a parallelogram mechanism and a driving motor are further arranged in each flapping wing frame and used for switching between the working state and the reset state of the flapping wings; the transmission mechanism is connected to the two connecting pieces; and the motor drives the transmission mechanism to move after being decelerated by the third speed reducer, so that the two connecting pieces synchronously swing up and down, and the two stepping motors respectively drive the two flapping wings to rotate after being decelerated by the two second speed reducers.

Description

technical field [0001] The invention relates to the field of movable-wing aircraft and flying robots, in particular to a double-synchronous swing parallelogram transmission rolling shutter flapping-wing unmanned aerial vehicle 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 of th...
