An extensive experimental investigation has been made of blunted fin-induced shock wave-turbulent boundary layer interactions. Surface pressures, heat transfer rate distributions and oil streak patterns were obtained over a range of fin bluntnesses and incidences for different incoming boundary layers. The freestream Mach number was 3 and the unit Reynolds number 6.2x107m(exp-1). Preliminary analysis indicates that over much of the interaction region the property distributions collapse using purely geometric parameters. In contrast to its two dimensional counterpart, which is a highly Reynolds number dependent viscous phenomenon, the current results seem to indicate that the three dimensional case is essentially inviscid.
