Unsteady pressure and force measurements associated with transonic buffeting of a two-dimensional supercritical airfoil

Buffet characteristics of the BGK No. 1 shockless airfoil have been investigated. Fluctuating pressure measurements along the airfoil chord and unsteady force balance data have been obtained in various regions inside the buffet régime close to the onset boundary curve. The Mach number range where buffet intensity reaches high values is...
