Re: [LML] LOP vs ROP Climb: Time and Fuel Burn (LIVP)
Jeff,
that's interesting. I wonder why you get
those high temps.
I wonder what is different in our engine
setups.
my CHT's are steady @380 in the max/max condition
@140knots.
It's been tested to 20,000 in that
config.
CHT's get better than that with less power or
more speed.
I have exhaust tunnel extensions which seem to make
a huge difference for cooling.
also have ceramic coated exhaust. I don't
know how much of a factor that is.
Some will say that 2700rpm is a bad idea because of
higher friction losses.
On the other hand the flame front always moves at
the same speed so if the
crank is turning faster your theta pp (angle after
top dead center where peak pressure occurs) is bigger
and the peak pressure is less. ....which
seems good for everything. the pulse on the crank
is not as concentrated, the CHT's are lower.
assuming everything else is setup right.
