Paul,
correction to the article:
"If the BSFC is 0.48 then this translates to mean 108 lbs./hour or 18
gals/hr of gasoline are burned. If the BSFC were lowered 14% then the
fuel burn would decrease to 0.41 or 15.4 gal/min."
----------------------------------------------------
That should be 15.4 gal/hr

Thanks Blake.
BTW I don't know of any current aircraft engine that will have
a BSFC that low. I think we can do better. I think we can get
20% better at 18,000 feet or .38 or 86.4 pounds per hour or 14.4 gallons
and hour. Not bad for any 225 HP internal combustion engine.
The higher you go the better it gets as the back pressure on
the turbine is reduced.
Here is a chart on that subject from the R3350 TC.
The rotary won't do as well as this as it is starting
from a higher number due to the poor combustion chamber
shape but on the other hand it has no exhaust valves
to fail and destroy the turbine. A common occurance
with the R3350 TC.

Ops forgot the chart.
Here it is.
