Mechanical transmission roller wing lift force generation device

Abstract

The invention discloses a mechanical transmission roller wing lift force generation device, and belongs to the technical field of aviation. The mechanical transmission roller wing lift force generation device comprises a rack, a main shaft, an arc guide rail and two rotor wings which are symmetrically distributed on the periphery of the main shaft and are of the same structure. Each rotor wing comprises a left rotating arm, a right rotating arm, a roller shaft, a roller wing, a guide wheel, a driving synchronous wheel, a synchronous belt, a driven synchronous wheel, a gear and a gear shaft. The main shaft is horizontally installed on the rack through a bearing. The lower surface of the arc guide rail makes contact with the guide wheels higher than the horizontal plane of the main shaft. When the guide wheels above the horizontal plane of the main shaft revolve around the axis of the main shaft, the roller shafts connected with the guide wheels will be driven to rotate automatically and the roller wings connected with the roller shafts are driven to rotate automatically. The autorotation direction of the roller wings is opposite to the revolution direction of the roller wings around the main shaft. The guide wheels below the horizontal plane of the main shaft will rotate automatically in the direction opposite to the direction in which the guide wheels above the horizontal plane of the main shaft rotate. The mechanical transmission roller wing lift force generation device is applied to a vertical lift aircraft to be used as a lift force device.

Description

Technical field [0001] A mechanical transmission roller wing lift generating device belongs to the field of aviation technology, and in particular relates to a roller wing thrust generating device. Background technique [0002] Traditional aircraft rely on wings or rotors to generate lift. The wing of an airplane and the rotor of a helicopter are similar in structure. Their cross-sections are all wing-shaped. Lift is generated by air flowing through the upper and lower surfaces of the wing to generate a pressure difference. When determining, the amount of lift they generate is related to the angle of attack, the size of the airfoil and the incoming flow velocity. The adjustment of the lift is achieved by changing the angle of attack, speed or the size of the airfoil. The relative thickness of the wing and the rotor are relatively thin, and the structural strength is poor. Fixed-wing aircraft have poor low-speed flight performance, require a large wing area, and cannot lift verti...
