抄録

In recent years, research and development activities for next generation supersonic transport are being carried out actively by the world aeronautical communities. In a supersonic intake, a cavity plays an important role in the control of shock waves. The supersonic intake flow tends to be unstable due to the interaction of shear layer in the cavity with oblique shock waves generated by ramp and cowl on the forebody. In the present study, the effects of cavity/oblique shock wave interaction and bleeding on the pressure oscillation in the cavity were investigated experimentally by a schlieren optical method and pressure measurements in the case of the flow Mach number 1.74 at the cavity entrance.
