Very interesting, thanks. And a great argument for variable pitch! What we do is like having a one speed car (almost like a Chevy powerglide 2 speed)... holds the engine back when you need the power (take off and climb), makes it available when you dont (at speed).
Back in the old days, KR's used to use a Warnke "almost constant speed" prop that flexed a bit to deliver a slightly lower pitch for takeoff, it was quite well regarded IIRC. I almost wonder why someone hasnt developed a spring-loaded hub, with the blades geared to each other so they have the same pitch but flatten out until RPM is reached. (Centrifugal governor pitch mechanism, with maybe a spring as well) > I think it is good reading to explain fixed pitch prop design power .vs. > climb > .vs. cruise. > > > _______________________________________________ Search the KRnet Archives at https://www.mail-archive.com/krnet@list.krnet.org/.
