LOP vs ROP Climb: Time and Fuel Burn (LIVP)
Jeff,
I think your full rich FF is (way) too
low.
How ROP are you at 34.2gph?
I believe continental specs for full throttle (38")
are 43gph.
For overhaul economy it would be good to get it up
there.
I have mine set at 45gph for
38"/2700rpm.
I don't know what temps that would give at 160knots
but at 140 knots the hottest cylinder is 380 and it
will climb at 2000fpm (not that I do that a lot)
If you want to use those numbers it takes 5 minutes
to do that climb which would be 3.75 gallons.
switch to cruise @260 knots at 16,000 and I think
you burn another 1.38 gals for a total of 5.13.
...so maybe a little less bad than you
said.
but somehow, a gallon and a half doesn't register
compared to the build cost, insurance, training, etc.
if I'm feeling environmentally responsible I just
think how much fuel I saved by not owning a
turbine....
