ABSTRACT

Study of supersonic flow onset slowly in time was fulfilled by Schlieren method. The experiments have been conducted for two initial installations of flat delta-wing. Different stages of the normal shock wave passage along the model with increasing of the total pressure are observed. Appearance of normal shock wave, bow shock wave, the flow separation zone near the nose bluntness, origin of the ?-shock wave and supersonic flow are detected. The results of the flow visualization show the high quality of the flow in wind tunnel T-325 test section.
