Didn't Mott
Taylor develop a clutch system that that used waffled disk and steel shot
to transfer torque with out transmitting the pulses to the prop? I think I
remember him demonstrating it at Oshkosh back in 81, but I've sleep
several places since then.}:>). You might be able to adapt something
like that to drive the RD-1.

There are two issues to cope with, one is
resonances and the other is transferring the torque pulses. The torque pulses
are transferred completely in a indefinitly stiff system. We do not want that,
because of the internal forces involved. That leaves the resonances created by
coupling and element flexing properties. I believe the only way to stay out of
the resonances is to keep them low. This is what ROTAX is doing, a 582 has
gear rattling around idle. When you watch a ROTAX starting up it is very
obvious when the rattling occurs. I have not observed any rattle on my C-Box
with the SOOB.
Thanks
Richard.
The 912S that was originally on the plane had a bad
rattle problem. If you didn't get it above about 2000 rpm on initial start,
you couldn't accelerate out of it. You just had to shut down, and try
again. That engine didn't have the "slipper clutch" that came out
as a mod for that
problem.
I'm looking
forward to playing with all this eventually, as it will be a neat
project.
