The invention relates to the technical field of aviation, in particular to a deformable wing assembly which comprises a fixed seat, a flexible piezoelectric actuator, a stacked piezoelectric actuator and a wing section. The fixed seat is arranged on the side surface of the wing section; the wing section is of a hollow shell structure; the flexible piezoelectric actuator is arranged on the rear edge of the interior of the hollow airfoil profile, so that the flexible piezoelectric actuator and the airfoil profile form an intelligent skin of a cantilever beam structure, and tiny continuous change of the airfoil profile is achieved. The stacked piezoelectric actuator is arranged at the front edge of the interior of the hollow airfoil profile, and when the stacked piezoelectric actuator is powered on, the airfoil profile deforms; according to the deformable wing assembly designed by the invention, the flexible piezoelectric actuator and the stacked piezoelectric actuator are fixed at specific positions in the wing, and then certain voltage is applied, so that rapid deformation of the wing is realized.

    本发明涉及航空技术领域,具体涉及一种可变形的机翼组件,该组件包括:固定座、柔性压电驱动器、堆叠式压电驱动器以及翼型;所述固定座设置在翼型的侧面;翼型为中空的外壳结构;柔性压电驱动器设置在中空的翼型内部的后缘,使得柔性压电驱动器与翼型形成悬臂梁结构的智能蒙皮,实现翼型的微小连续变化;堆叠式压电驱动器设置在中空的翼型内部的前缘,当堆叠式压电驱动器通电时,使得翼型发生形变;发明设计了一种可变形机翼组件,该组件将柔性压电驱动器、堆叠式压电驱动器固定在机翼内部特定位置,然后施加一定的电压,从而实现机翼的快速变形。
