A winglet system for a wing of an aircraft is provided. The winglet system comprises an attachment end for attachment to a main wing of the aircraft, an upper winglet and a lower winglet. The upper and lower winglets are staggered and also overlap one another along the chord of the attachment end. A spanwise profile of the lower winglet has a midpoint where a slope of the spanwise profile at a point outboard of the midpoint is inclined more upwardly than a slope of the spanwise profile at the midpoint. The configuration of the winglet system may provide benefits such as a reduced bending moment and reduced negative interference between the winglets while also managing ground clearance.
飞机的小翼系统。本发明提供了一种用于飞机机翼的小翼系统,所述小翼系统包括:附接端,其用于附接到飞机的主翼;上小翼;和下小翼。所述上小翼和下小翼沿附接端的弦彼此错开并且也彼此重叠。所述下小翼的翼展方向轮廓具有中点,其中翼展方向轮廓在中点的外侧的点处的斜率比翼展方向轮廓在中点处的斜率更向上倾斜。所述小翼系统的构造可以提供益处,诸如减小弯矩,并且减小小翼之间的不利干扰,同时控制离地距离。
