The present invention relates to a winglet which is provided at a spanwise outer side of a wing of a fixed-wing aircraft and comprises: a support structure which supports the winglet; the skin is attached to the supporting structure and comprises an upper skin body arranged on the upper portion of the supporting structure and a lower skin body arranged on the lower portion of the supporting structure, and a leading edge skin body is formed at the position where the upper skin body and the lower skin body are connected; the piezoelectric device is attached to the inner surface of at least one of the upper skin, the lower skin and the leading edge skin, and the piezoelectric device can be driven to deform, so that the skin deforms along with deformation of the piezoelectric device. By means of the arrangement, the wing shape of the winglet can be changed according to expectation, and therefore the winglet with the high-low-speed aerodynamic performance is achieved in an active flow control mode. In addition, the invention also relates to a fixed-wing aircraft and a method for controlling an airfoil of a winglet.

    本发明涉及一种翼梢小翼,该翼梢小翼设置在固定翼飞行器的机翼的展向外侧处并且包括:支承结构,支承结构支承翼梢小翼;蒙皮,蒙皮附连到支承结构并且包括设置在支承结构上部的上蒙皮和设置在支承结构下部的下蒙皮,其中,在上蒙皮与下蒙皮连接的位置处形成前缘蒙皮;以及压电装置,压电装置附连到上蒙皮、下蒙皮和前缘蒙皮中的至少一个的内表面,并且压电装置能够被驱动发生变形,使得蒙皮跟随压电装置的变形而发生变形。这种布置能够根据期望来改变翼梢小翼的翼形,从而以主动流动控制方式实现兼顾高低速气动性能的翼梢小翼。另外,本发明还涉及一种固定翼飞行器以及用于控制翼梢小翼的翼型的方法。
