It is well known that external localized flow heating upstream of supersonic blunt bodies can help to reduce their wave drag and to save the thrust required for a supersonic flight. Regardless of numerous investigations published in the last decades to this topic, an unambiguous statement about the real potential of the thermal effect of energy addition (EA) is missing up to now. Impressive quantitative discrepancies in the effects indicated experimentally and numerically are the reason for that. In the framework of the investigations running at the department this question should be addressed experimentally and numerically.
