Problems solved by technology

However, since the rotor of the rotorcraft is stationary relative to the central axis of the rotor, the forward resistance is relatively large, so the energy consumption is large, the aerodynamic efficiency is low, and it is difficult to fly with high power and long endurance

Abstract

The invention discloses a single-wheel movable-wing aircraft with rotatable blades and fixed wings, which comprises a wheel-type movable wing, a transmission mechanism, a cam, a rotating shaft, a reducer, an electric motor, a fuselage frame, a fixed wing, and a rudder. Aircraft and counterweight, the electric motor set on the fuselage frame drives the rotating shaft to rotate continuously after being decelerated by the reducer. The axis direction of the rotating shaft is perpendicular to the longitudinal symmetry plane of the aircraft. The wheeled rotor includes a rotating frame and rotatable blades installed in the rotating frame. The cam and transmission mechanism are used to control the rotation and reset of the blades. The fixed wing is provided for generating lift, the fuselage frame is provided with a steering gear for controlling the flight direction, and the fuselage frame is provided with counterweights for maintaining the left and right balance of the fuselage. The invention can be widely used in various small aircraft flying with low Reynolds number.

Description

technical field [0001] The invention relates to the field of movable-wing aircraft and flying robots, in particular to a single-wheeled movable-wing aircraft with fixed wings and rotatable blades. Background technique [0002] There are three flight types of aircraft: fixed wing, rotary wing and flapping wing, both of which are movable wings. [0003] Flapping wing flight is a flying method 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. Flexibility, more suitable for performing flights around obstacles etc. 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. At present, the research of flapping-wing aircraft mainly focuses on designing variou...
