Keywords: Busemann biplane, Pressure-Sensitive Paint, Shock interference

The pressure distributions on thin wings of the Busemann biplane model were measured to investigate the wave cancellation mechanism using Pressure-Sensitive Paint. The complicated three-dimensional interference phenomenon between the two wings, including shock wave/boundary layer interactions were observed and compared with CFD results and the Schlieren images.
