Doug, I have some questions after reading the Turbo Compounding report.

You say: "For ease of installing the unit near the front of the rotary it is
best that the input
shaft and output shaft both turn in the same direction."

Which end are you describing as the front of the rotary? Need a more definite
term here as the engine is oriented differently in pusher vs tractor planes. Also, which shaft
do you mean by output
shaft? The engine output shaft or the turbine output shaft?

Also, it is not clear to whether you are using just the reduction drive from
the rotrex or the whole
unit including compressor as well.

Thanks,

Hans

Yes we do  have tractor and pushers airplanes and that is why it is less
confusing to refer to engine part in the way Mazda designed it. Flywheel and
bell housing in the back, water pump on the front.   Feel free to clarify it
by inserting  (water pump side).


Next I was speaking about the traction drive.


It should read "For ease of installing the traction drive near the front of
the rotary ( water pump side) it is  best that the traction drives' input
and output shaft both turn in the same direction as the engine e shaft. That
is clockwise when looking at the front of the engine.


Hans just for your understanding the ROTREX traction drive would not be used
with the compressor attached.  Another complete unit #C30-94 model I
referred to might be used to boost the engine though.

This traction drive part of the unit can only be used 'as is' if it could be
connected to a custom designed turbine rotating counter clockwise as viewed
from the front of the engine. On the particular design I have in hand I
don't think it is safe to try and modify it.

Paul is trying to address this problem by making a completely new traction
drive taking the power off the planetary.

The design of the 'final' custom turbine is a ways off but I have noticed
Horace Ho at <http://jetbeetle.com/>  in Taiwan has already been making and
selling some nice

" custom cast turbine wheels, NGVs for you, covering sizes from 55mm, 60mm,
66mm, 70mm, 90mm,130mm, and any sizes in between, you name it, we build it.

Here are what we have done for our customers :

*    Two different turbine wheels, a 55mm size,$B"w(J and a 60mm size, with
redesigns for improving the blade's mechanical strength and aerodynamic
performance, so that it is near optimization.




Thanks for catching the mistakes..

Doug, can that guy build them in Inconel?
