Reciprocating linear movement roller airfoil lift force generating device

Abstract

The invention provides a reciprocating linear movement roller airfoil lift force generating device and belongs to the technical field of aviation. The reciprocating linear movement roller airfoil lift force generating device comprises a spindle, a rack, a turntable, a slide block, a translation frame, a roller airfoil, a front press plate and a rear press plate. The turntable is horizontally installed at the upper end of the spindle. A front guide rod is installed on the rack through a front left linear bearing and a front right linear bearing. A rear guide rod is installed on the rack through a rear left linear bearing and a rear right linear bearing. A guide rail is connected with the slide block, and the slide block can flexibly slide along the guide rail back and forth. The translation frame with the roller airfoil can be driven by the turntable and the slide block to perform left-right reciprocating translation. The front press plate is attached to the front end of the roller airfoil and located at upper portion of the roller airfoil. The rear press plate is attached to the rear end of the roller airfoil and located at the upper portion of the roller airfoil. When the translation frame performs leftward movement, the roller airfoil rotates clockwise. When the translation frame performs rightward movement, the roller airfoil rotates anticlockwise. Under the driving of power, the reciprocating linear movement roller airfoil lift force generating device can produce thrust and can be applied to a vertical lifting aircraft to serve as a lift force device.

Description

Technical field [0001] A reciprocating linear motion drum wing lift generating device belongs to the field of aviation technology, in particular to a drum wing lift 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. Adjusting the size 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 vertically. Th...
