U.S. Air Force researchers are working on what they call a Variable Camber Compliant Wing, which can change its shape mid-flight. The wing would operate autonomously, changing its camber depending on flying conditions to maximize the plane's aerodynamic efficiency. By flexing into a shape with low camber, the wings would enable the plane to travel faster and save fuel. A high-camber shape, on the other hand, would increase the drag on the aircraft.
