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

Abstract

The invention relates to a bisynchronous direct-acting curtain-pulling type driving-energy-adjustable flapping-wing unmanned aerial vehicle. The unmanned aerial vehicle comprises curtain wings, a fuselage top plate, first speed reducers, driving motors, connecting pieces, second speed reducers, stepping motors, a transmission mechanism, a fuselage bottom plate, a third speed reducer, a motor and sliding ways; the four sliding ways in the vertical direction are symmetrically and fixedly mounted on the periphery of the fuselage top plate, and the two curtain wings can slide on the sliding ways; meanwhile, the two curtain wings are connected to the two connecting pieces respectively and can rotate relatively, each curtain wing comprises a curtain wing frame and a soft curtain mounted on the curtain wing frame, and coil springs and driving motors are further arranged in each curtain wing frame and used for controlling the soft curtain to be unfolded and folded; the transmission mechanism is connected to the two connecting pieces; and a motor arranged on the fuselage bottom plate is decelerated through a third speed reducer and then drives the transmission mechanism to move so that the two connecting pieces can synchronously slide up and down, and two stepping motors arranged on the two connecting pieces respectively are decelerated through two second speed reducers and then respectively drive the two curtain wings to rotate.

Description

technical field [0001] The invention relates to the field of movable-wing aircraft and flying robots, in particular to a double-synchronous direct-motion curtain-driven energy-adjustable flapping-wing unmanned aerial vehicle. 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 ...
