Salut George
My PSRU has been in use on my Zenair Zenith
since 1995. I have logged 33 hrs flight time plus at least as much ground
running. I dismantled it last fall for inspection and lubrication. Belt,
sprockets and bearings are in excellent condition. Total weight is about 53
lbs.
The PSRU is driven from a Mazda RX-7
automobile clutch which is bolted to the 13B flywheel.
As for the design, you would need to
contact Richard Finch himself. Perhaps a Google search...

Yvon,
I would be interested in how this works for you
in terms of life of belts etc. I would also be interested in the design for my
single rotor. Do you incorporate torsional vibration isolators or rely on the
belt to do that work?

Allo Bernie
The cog-belt PSRU that I fly is based
on Richard Finch's 1986 design. I had some parts made by a machine shop and
I put it together myself and adapted it to my 13B engine. The belt and
sprockets are Gates Poly Chain GT products. RPM sprocket limit 3200
rpm. Gates rates the belt HP limit at about 150 HP

Sorry,
I don't have an answer, but I would like to know more about your cog-belt
PSRU, who makes it and what are the operating limits (like HP limit, RPM
limit, etc.). Thank you. Bernie
