Variable camber wing

Variable camber wing

Variable camber wing is a design of aircraft wing by V.J. Burnelli that changes the camber of the airfoil (1933), and varies the area and camber of the wing (1937).

This is depicted in the figure below. A mechanism moves and rotates the leading and trailing edge to gain camber and wing area.The wing was used in the Nurnelli GX-3 aircraft, which first flew in 1929. The shaft to control the mechanism was controlled by a hand wheel while that running parallel to the rear spar was driven by a chain from the forward one. In order to minimize the movement of the center of pressure, the mechanism was designed in such a way that it provided higher movement in the leading edge than in the trailing edge. The various flaps and slats on the control surfaces of modern commercial airliners perform a similar function.
