A morphing trailing edge device for an airfoil includes a skin member, an actuator, and a torsion element. The skin member is configured to extend on a surface of a trailing edge region of an airfoil and includes a load introduction point within a reinforced area. The skin member further includes a stiffening member arranged essentially perpendicular to the load introduction point, wherein the load introduction point, the reinforced area and the stiffening member are integrated into the skin member. The actuator is configured to drive the torsion element with an actuation load. The torsion element is configured to translate the actuation load to the load introduction point, so that the actuation load morphs the trailing edge region up- or downwardly relative to a horizontal plane. A morphing airfoil for an aircraft, an aircraft with a morphing airfoil and a method for manufacturing a morphing airfoil are also described.
