Hi Ed,
No, this will utilize the typical oil driven type cs prop governors
found on 99% of aircraft now. It will be fed and will supply oil to the
prop hub just like most typical cs props-just like Mistral's unit and
the Marcotte unit (but much more economical, if we can pull it off). I
want to use a Whirlwind type prop-they use Hartzell type cs hubs. It
will have a typical SAE cs type prop flange. Use any cs prop. It is
based on a planetary reduction in production for other uses
(helicopters) in Eastern Europe.

Marc, I assume this is an electrically controlled CS PSRU rather than
a
hydraulic type? Just Curious.

Subject: [FlyRotary] CS psru development
I have some preliminary information on the cs planetary psru I am
helping
develop. Reduction ratio presently 2.92! Great reduction ration for
rx8s.
It looks like the actual position of the propeller governor from the
propeller shaft centerline to the top of the governor is 290 millimeters
(11.5 inches) and the angle is 35 degrees from the vertical position.
The
reducer length from the propeller shaft flange to the engine would be
about
400 millimeters (15.75 inches) and the weight of the reducer will be
about
32 kilograms (70.5 lbs).
Please ask questions so I can figure out the most flexible package.
Does anyone know the Marcotte weight or the Mechanir weight of their
cs
psru's? I know Tracy's non cs is about 45 lbs.
