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.

Paul and everyone,
Thanks for the help in getting the report posted. Their are still a few
pesty less than or equal to characters in there.??? ≦ Probably junk
characters from the Japanese side of things and formatting misalignment on
the end of the paragraph Blake mentioned.
Doug in Japan
I have looked at the html source code and it is too time consuming
for me to maintain. I hope Daniel can program in html to fix
some of these problems. It will stay as is until somebody
fixes it.
