On a lighter note, what is your thoughts on coupling
a exhaust turbine to the crankshaft, via cog belt or micro v belts? My
thoughts are to stop the vibrations of the crankshafts getting thru to
the turbine, while extracting the energy from the exhaust.
I also have not been able to locate the suppliers of
alloy end bits for the rotary engines.
Thanks

Paul, we have an interest in a similar setup replacing the gearbox with a
starter/generator and deleting the compressor.

Will the generator run at 100,000 RPM?

High speed microturbine electric generators are common state of
the art in low power (50 to 200 kW) cogeneration sets.
The 80,000+ RPM, 2 poles or homopolar generators are reliable
industrial machines...  for still ground based installation,
not for flying machines with angular velocity and accelerations.

As a minimum requirement for aircraft use, I would place the
turbogenerator axis parallel to the roll axis of the airplane,
axis of maximum rotational speed, and, of course, avoid aerobatics.

What is the efficiency of the generator alone Philippe?
