The article presents the results of recent studies of direct current discharge in a supersonic flow and
its application for plasma-assisted combustion. Properties such as the dependence of the discharge
temperature on the current and the current-voltage characteristic are described, and the results of
modeling a discharge in a supersonic flow in the CFD software Plasmaero and FlowVision are presented.
Based on previous results and new information obtained about the discharge and the features of
plasma-assisted combustion, an experiment on the ignition of gaseous fuel in a supersonic flow under
conditions where the fuel is pre-mixed with air and supplied in supersonic mode to the core of a
supersonic flow is proposed and tested. This formulation of the problem excludes the influence of
mixing and subsonic separation zones on the result of the experiment. It is shown that, despite
preliminary mixing, an elongated powerful plasma channel is required for ignition.
