Potential of Localized Flow Heating for Wave Drag Reduction
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. According to published results the power effectiveness ratio η, defined as the ratio of the thrust power saved to the heating power introduced, is the most-recognized dimensionless parameter quantifying this drag reduction effect.
