The paper deals with the problem of pulse discharge localization in a supersonic and transonic non-homogeneous flow and its use for flow control. Discharge plasma was shown to be localized in zones of low density - in front of shock wave and in vortex separation zones - at rear side of the wedge and at shock interaction with boundary layer. The amplitude of electric current localized in vortex may be twice higher than in homogeneous gas flow.The Riemann problem conditions on ionized shock wave front are confirmed by series of images, obtained with high speed shadowgraphy.
