As Boeing’s 787 illustrates, airliner wings are more slender than they used to be. But as wings get slimmer in pursuit of lower drag and lighter weight, flutter becomes a greater concern. Flutter is ...

Flutter kills. When a vibration, usually in an aircraft's wing or tail, matches the natural frequency of that structure, the results of that "flutter" can be catastrophic. If the vibration isn't ...

Long, narrow wings are intended to reduce fuel consumption and increase comfort in aircraft. However, wing flutter must be eliminated for this to happen. The US space agency NASA and the aircraft ...

According to NASA, the future of long-range aircraft lies in long, thin, flexible wings, which can develop as much lift as the relatively short, wide wings on today's airliners, but dramatically ...

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 ...
