An actuator is coupled to a driven surface and actuated to move the driven surface and change the shape thereof, ::::) with the non-driven surface changing its shape in response to actuation of the driven surface. The upper and lower surfaces can be N part of a sub-flap mounted to a traditional 0 isting structure in the flap, or the flap components can be mounted to the sub-flap. The upper and lower surfaces can alternatively re- place the traditional flap in the fixed wing of an aircraft. The upper and lower surfaces are continuous and can be deflected upward, downward, or twisted in a span-wise direction relative to the flap or wing.
