The invention discloses a wing with a deformable and reconfigurable airfoil profile. The wing comprises a flexible skin and a supporting framework, the flexible skin covers the supporting framework, is a shape maintaining component of the supporting framework and is used for transmitting force between air and the supporting framework. The supporting framework comprises a driving unit, a control unit, wing ribs and wing spars; the wing ribs and the wing spars are fixedly connected to form a latticed rectangular frame, the wing ribs are distributed in the length direction of the wing, and the wing spars are distributed in the width direction of the wing; a driving unit is mounted in each grid of the latticed rectangular frame, each driving unit is connected with a spar located at the front end of the driving unit, and all the driving units on the same spar are completely consistent in size and shape; determining the sizes of the driving units on different spars according to the requirement of the airfoil variation range; the driving unit is used for supporting the flexible skin and transmitting force borne by the flexible skin to the supporting framework. The control unit is used for controlling all the driving units to generate height change along the thickness direction of the wing, and the flexible skin is supported by using the driving units with different heights to form wing sections with different thicknesses. The problems that wings of an aircraft are single in airfoil profile in the flight process, complex flight working conditions cannot be fully met, and the flight efficiency is low can be solved.

    本发明公开了一种翼型可变形重构的机翼,包括:柔性蒙皮和支撑骨架;柔性蒙皮包覆在支撑骨架的外部,是支撑骨架的维形部件,用于传递空气和支撑骨架之间的力;支撑骨架包括:驱动单元、控制单元、翼肋和翼梁;若干翼肋和若干翼梁固定连接组成网格状的矩形框架,其中,翼肋沿机翼的长度方向分布,翼梁沿机翼的宽度方向分布;网格状的矩形框架的每个网格内均安装有一个驱动单元,且每个驱动单元均与位于其前端的翼梁连接,同一个翼梁上的所有驱动单元的大小和形状完全一致;根据翼型变化范围的需要,确定不同翼梁上的驱动单元的大小;驱动单元用于支撑柔性蒙皮,并将柔性蒙皮的受到的力传递到支撑骨架上;控制单元用于控制所有驱动单元发生沿机翼厚度方向的高度变化,柔性蒙皮通过使用不同高度的驱动单元支撑,来形成不同厚度的翼型。本发明能够解决飞行器的机翼在飞行过程中翼型单一,不能充分满足复杂飞行工况,飞行效率低的问题。
