Transverse sonic jet (nitrogen) was injected from a circular injector on an inclined fiat plate into asupersonic cross flow. Flow characteristics of a jet was organized by a penetration height of jet dependedon the jet-to-freestream momentum flux ratio. The resuｌts showed that the penetration height wasproportional to thejet-tｏ-freestream momentum flux ratio to the power of 0.68 (M1 = 1.7) or 0.70 (M1 =3.3). Furthermore, in order to investigate the interaction between boundary layer on the flat plate andshock wave generated by the transverse sonic jet, chamcteristics of separated boundary layer and bowshock wave were observed. The separated boundary layer region and scale of bow shock could be foundto be increased as the jet-to-freestream momentum flux ratio increased. The results also showed that theshock wave/boundary layer interaction had influenced on the penetration height of jet.
