Well, Bruce Bohannon claims 283KTAS at 40,000 -70F in the Flyin’ Tiger. I recall the .5 number but the 284KTAS seems slow? Can anyone confirm the number at that altitude and temperature?
Who said RVs aren’t fast??
Get a F1 Rocket everyday is 200 Kts!!
Literally off the back of an envelope:
at 200 mph, pressure rise ~5%, temp rise ~1.3% or
~7 degrees F.
I don't know what venturi effect is with an air scoop.
