Potential of Localized Flow Heating for Wave Drag Reduction
- 329 Downloads
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.
