Abstract

Structural fin or wing vibrations are observed on high performance aircraft when flying at high angles of attach. The severity of the so-called buffeting vibration depends on the aircraft configuration and aerodynamic optimization of the configuration. The vibrations are caused by flow fluctuations resulting from flow separation at wings or from bursting of wing leading edge and front fuselage vortices. The resulting dynamic loads with maneuver loads lead to increased material fatigue and may require an augmented effort in aircraft maintenance.
