I used the equation that Lipps mentions in the article in
CONTACT! to Calculate "Effective Pitch" of my 74x88 prop. His equation
(with some clarifying annotations) is
Effective Pitch ( % ) = TAS (mph) *1056/RPM(Props' RPM
not engine)
EF = 168*1056/2105 = 84.27 effective pitch
Since my Props pitch is suppose to be 88" could this mean
I have a bit of "Slippage"? Actually, I was impressed that the calculation
came out as close as it did - within 4% of its 88" of pitch.
Thanks Pat
