Now a “smart” material which damps that vibration could preserve airframes – and even make planes less noisy. The vibrations are generated when vortices resulting from the plane’s motion through the air pass over the aircraft’s skin. Over time, this “flutter” stresses the skin and shortens the life of the plane. “Commercial aircraft are designed for 40,000 to 60,000 flights,
