Spoiling devices deployed rapidly to prevent damage to airfoil surfaces. When flutter spoiler deployed, unsteady aerodynamic forces changed and flutter dynamic pressure increased. Because flutter spoiler deployed rapidly, violent increase in vibration amplitude that usually occurs at flutter prevented from occurring. Consists of one or more platelike structures hinged along leading edge to surface of wing or other lifting surface so spoiler rotated outward into airstream. Located on both upper and lower airfoil surfaces, but used on either. When not in use, fold against or into wing surface so aerodynamic contour of wing remains unchanged.
