摘要

NASA has actively suppressed flutter of a flexible wing in flight, potentially paving the way for lighter, lower-drag wings on future fuel-efficient aircraft. The feat was demonstrated on flights of Lockheed Martin's X-56A at NASA Armstrong Flight Research Center at Edwards AFB, California.Flutter is an aeroelastic instability that can lead to structural failure. Conventionally, wings are designed to be stiff enough that the airspeed and dynamic-pressure boundaries for flutter onset are well outside the aircraft's normal flight envelope. But this safety margin adds weight to the structure.
