Why not reduce more, go all the way to
nearly flat pitch, from what I remember that prop is a little on the big side
for the Kolb, isn't it.
Even if it doesn't
produce any thrust (flat pitch), it works as a flywheel - At least you
eleiminate ANY ( if there is...) stall issues at the tips....
Hi Thomas,
I thought about reducing it even more, but just don't believe
it could be stalling at 10
degrees.
And why don't you
have that brandnew, easy to work with, etc. ACES on the machine, yet??
You're absolutely right
about the need to put the ACES analyzer on the engine. The only
problem with that is time. The decision has been made to defer the
single rotor project, and put my full attention on the RV-8. I'm
therefore trying to resist taking the ACES to the hanger. I'm
really looking forward to the whole science project, but I just ain't gonna do
it now.
What I say is: You
HAVE a vibration analysis tool - and an easy to use one! Try it! Props is just
one ofthe many uses!
Trying hard to
resist...
did you consider to run
the PSRU without dampers? Even if you get a buzz or something like that you know
that the dampers where the wrong ones....
I've considered it, but machining the solid dampeners
would take more time than I'm willing to spend at the moment. As you say,
it would make a difference, but good or bad is anybody's guess. I actually
believe I need much softer dampeners, but I don't think there's enough room to
make them give enough. Keep in mind that this is nothing more than a
SWAG.
Thanks for the comments.
