Flutter aerodynamics
WebFlutter is of great concern to any pilot, since excessive flutter has caused a number of aircraft to lose control and crash. Although any surface on an aircraft which is exposed to air flow can experience aerodynamic flutter, the most common type of flutter involves the control surfaces such as ailerons, elevators, and rudders.
