Novel aerofoil by utilizing magnus effect

一种利用马格纳斯效应的新型机翼

Abstract

本发明提出了一种利用马格纳斯效应的新型机翼,包括柔性蒙皮、翼肋、梁、机翼前缘滚筒和驱动装置;驱动装置驱动机翼前缘滚筒转动;翼肋前端为圆弧凹陷结构,在圆弧凹陷面上安装有滚动轴承,机翼前缘滚筒处于翼肋前端圆弧凹陷结构内,与翼肋通过滚动轴承配合;在翼肋周向边缘还安装有若干滚动轴承,柔性蒙皮包裹由机翼前缘滚筒、翼肋和梁组成的机翼框架,机翼前缘滚筒能够带动柔性蒙皮绕机翼框架滑动。本发明克服了现有技术中利用圆筒形机翼产生马格纳斯升力时阻力大的不足,且相比于传统机翼,在低速飞行时,本发明只需调节电机转速,使得蒙皮的滑动速度增加,也可使机翼获得较大升力,增加载重,并实现短距起降,降低跑道要求。
The invention discloses a novel aerofoil by utilizing a magnus effect. The novel aerofoil by utilizing a magnus effect comprises a flexible skin, wing ribs, beams, an aerofoil leading edge roller and a driving device, wherein the driving device drives the aerofoil leading edge roller to rotate; the front ends of the wing ribs are of circular arc concave structures; circular arc concave surfaces are provided with rolling bearings; the aerofoil leading edge roller is positioned in the circular arc concave structures at the front ends of the wing ribs, and are matched with the wring ribs through the rolling bearings; a plurality of rolling bearings are also installed at the peripheral edges of the wing ribs; the flexible skin wraps an aerofoil framework consisting of the aerofoil leading edge roller, the wing ribs and the beams; the aerofoil leading edge roller can drive the flexible skin to slide around the aerofoil framework. According to the novel aerofoil, the defect that the resistance is high as a cylindrical aerofoil is utilized for generating magnus lift force in the prior art is overcome; compared with the traditional aerofoil, the novel aerofoil has the advantages that when the aerofoil is in low-speed flight, only the rotation speed of a motor is required to be regulated, so that the slide speed of the skin is increased, also the aerofoil can obtain greater lift force; the loading weight is increased, and short-distance taking-off and landing are achieved, and the track requirement is lowered.
