Geometric morphing wing with adaptive corrugated structure

摘要

An airfoil member includes an airfoil skin, a trailing edge member, a spar member extending in a lateral direction within the airfoil skin, and an airfoil member morphing device configured to modify a shape of the airfoil skin. The device includes at least one motor or actuator, an airfoil skin support sheet attached to the spar member and corrugated to define alternating upper and lower lines of contact with inner surfaces of the rearward upper skin and rearward lower skin. Actuating bands extend from the spar member through alternating upward and downward sections of the airfoil skin support sheet and are operably connected to the at least one motor or actuator. The airfoil member morphing device is configured to independently adjust a camber, twist, and chord length of the airfoil member.
