Variable camber wing

From Wikipedia, the free encyclopedia

Variable camber wing is a design of aircraft wing that allows changes in the camber (or curvature) of the airfoil. Any aircraft wing fitted with flaps or ailerons or a leading edge droop is by definition a variable camber wing; however, the term is usually applied only to wings that are capable of doing so without resorting to conventional flaps. Many early patents for flaps described them as variable camber devices notwithstanding. [clarification needed] Several mechanisms have been tried, including a device that controls the location and shape of the entire upper surface of the airfoil, a retractable bridge that connects two separate high aspect ratio wings, turning them into a single low aspect ratio wing or with telescopic segments that could be forced out, increasing the thickness, chord and shape of the affected portion of the wing.
