Abstract

The principle step in investigation of MW discharge in supersonic (SS) flows has been made. The detailed spatial-temporal data of discharge domains evolution and interaction with the BSW are obtained. They include synchronized information from optical emission diagnostics via using of hemiluminescence for discharge regions tracing, from the pressure sensors, which provide information about temporal evolution of the total pressure at stagnation point and Schlieren pictures available with time step of order of microsecond. Experiments were conducted under M-number 1.7-1.8 and peak MW power 210kW not only in airflow, but also in nitrogen, argon and carbon dioxide. All this, along with additional information about real discharge structure and gas temperatures in different plasmoids allowed to reconstruct the sequence of events in the process of discharge regions - AD model interaction, to formulate the regularities of such interaction and to eliminate those questions which are to be answered in further investigations.
