free propeller efficiency (analytic)
(OP)
Hi all,
I'm looking for an analityc formulas that describe the propeller efficiency (eta) function of the variables J=v/nd and propulsive coefficient cp (renard). In particular i have to do with a McCauley costant speed propeller the one mounted on piper pa28r.
Thanks all in advance i hope u can help me

Yes it's for college, i have to implement a program with matlab to calculate performances of g.a. airplanes, depending on airplane geometry and propulsive characteristics, like the AAA program of darcorp.

Anyway thanks for the help. I hope to be graduate in June so i could post for work issue.
