Keywords: supersonic intake, buzz, shock tunnel, flow visualization, pressure-sensitive paint

The purpose of this study is to quantitatively visualize unsteady behavior of shock waves (buzz) and boundary layer by anodized aluminum pressure-sensitive paint (AA-PSP). From the results of surface pressure distribution and shock wave structures, we clearly confirmed buzz around the supersonic intake model at subcritical state.
