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 fluttering flying chess cannot realize vertical take-off and landing and hovering in the air, and their flexibility and maneuverability are not good enough.

Abstract

The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a low-resistance synchronous direct-acting double flapping-wing aircraft. It includes flapping wings, slides, connectors, first reducer, stepping motor, transmission mechanism, second reducer, electric motor and fuselage frame, and two vertical sliding slides are installed and fixed symmetrically on both sides of the fuselage frame. The two connecting parts are respectively slidably connected to the two slideways, and the two flapping wings are respectively connected to the two connecting parts and can be rotated relatively. The flapping wing frame is also equipped with a torsion spring for the reset of the blade. The transmission mechanism is connected to the two connecting parts. The motor set on the fuselage frame drives the transmission mechanism to move after being decelerated by the second reducer to make the two The two connecting parts slide up and down synchronously, and the two stepping motors on the connecting parts are decelerated by the first reducer to respectively drive the two flapping wings to rotate.

Description

technical field [0001] The invention relates to the field of flapping-wing aircraft and flying robots, in particular to a low-resistance synchronous direct-acting double flapping-wing aircraft. 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.
