Embodiment 1

[0038] A fixed-wing aircraft includes a fuselage and wings fixed on the fuselage, such as Figure 1 to Figure 4 As shown, the wing includes a wing body 1 extending left and right and a self-rotating fairing device 2 assembled on the wing body 1 . When the fixed-wing aircraft receives the airflow from front to back, the self-rotating rectifying device 2 will produce a Magnus effect to increase the lift force on the wings, thereby improving the flight performance of the fixed-wing aircraft.

[0039] The wing body 1 includes a wing shell 3 and a skin 4 covering the surface of the wing shell 3. The wing shell 3 includes an arc-shaped upper panel 5, a horizontal lower panel, and a connecting arc-shaped upper panel 5 and a horizontal lower panel. The wing rib 6 and the movable aileron 7 are connected to each other with the rear side of the horizontal lower panel. The movable aileron 7 can swing up and down within a certain angle range to adjust the maneuverability of the aircraft. ...

Abstract

The invention relates to a wing and a fixed-wing aircraft, the wing comprises a wing body extending left and right and a self-rotation rectifying device, and the self-rotation rectifying device comprises a rotating shaft and an S-shaped plate arranged on the rotating shaft; the wing body comprises a right branch wing and a left branch wing, the S-shaped plates are arranged on the right branch wing and the left branch wing, and the S-shaped plates on the right branch wing and the S-shaped plates on the left branch wing are symmetrically arranged; projections of the S-shaped plates on the right supporting wings in a plane perpendicular to the rotating shaft are uniformly arranged in the circumferential direction of the rotating shaft by taking the rotating shaft as a center; each S-shaped plate comprises two bent plates located on the two sides of the rotating shaft respectively, and when the S-shaped plate is in a vertical state, the middle of the bent plate located on the upper side protrudes backwards. According to the invention, the lift force is provided for the wings through the Magnus effect generated by the rotating S-shaped plates, and the problem that an existing small fixed-wing aircraft is insufficient in lift force is solved.

Description

technical field [0001] The invention relates to a wing and a fixed-wing aircraft, belonging to the field of aircraft. Background technique [0002] The main characteristics of small fixed-wing aircraft are fast maximum flight speed, large load capacity, relatively simple design structure, and large cruising radius. However, compared with traditional fixed-wing aircraft, small fixed-wing aircraft are smaller in size and lighter in weight, and the minimum speed required for small fixed-wing aircraft to take off is lower, and the viscous effect is prominent at low Reynolds numbers, so the viscous force cannot be ignored. , so that the lift-to-drag ratio drops sharply, and small fixed-wing aircraft face the problem of insufficient lift. Contents of the invention [0003] The purpose of the present invention is to provide a wing to solve the problem of insufficient lift of existing small fixed-wing aircraft. The present invention also provides a fixed-wing aircraft comprising...
