When the pressure ratio across the convergent nozzle exceeds the critical pressure ratio (1.893 for air), the jet becomes underexpanded. With the flat plate placed numerically in the jet the so-called "plate shock wave" appears in the front of the plate. It's essential to pursue the factor of this shock wave in detail. In the present study such flow field is visualized and the pressure distribution on the plate is measured in order to make clear the behavior of the plate shock wave and the flow pattern of the impinging jet. In the study, then, the flow field was cleared by using the experimental equipment which modeled the exhaust jet stream on the rocket or a vertical short take-off and landing aircraft.
