• Concerning the overexpanded supersonic jet, interaction between the normal shock wave immediately downstream of the D'Laval nozzle exit and the shear layer of the jet boundary was investigated experimentally. The following were demonstrated. (1) The normal shock wave changes into a pseudo-shock wave immediately after its occurrence in the flow, (2) the pseudo-shock wave is several jet diameters in length but somewhat shorter than the pseudo-shock wave in duct flow, (3) its pressure ratio is extremely small compared with that of the normal shock wave and nearly proportional to the Mach number immediately upstream of the pseudo-shockwave.
