' supersonic'
From Wolf-Heinrich Hucho:
Blue Flame:
1) Cd 0.20 subsonic
2) Cd 0.60 supersonic
NOTE: From reporting of the original THRUST supersonic LSR car, the supersonic Cd varies by about 30%, depending on whether or not the exhaust thrust cone is present or not. Which jives well with what NASA found on lifting body reentry vehicles, Space Shuttle, and the X-15, which were around Cd 0.65.
