Paul,

I heard that you'll be attending COPPERSTATE and would like to present an
alternative engine forum on Saturday morning.

What will your topic be?

Are you interested in presenting on the other days as well?

Thanks!

I did not agree to that. I agreed to a  question and answer session
on rotaries. Not other alternative engines. If it is on ALL alternative
engines I will pass.

Paul,

I would think it would not be difficult to speak about ALL alternative
engines.

Besides the Reciprocating two-strokes and four-strokes, there is only
the rotary Wankel type and the turbine.

The turbines are usually too expensive in many way, initial cost,
maintenance and in fuel consumption.
The RP-engines are known in general, there is no need to discuss these.
Here you just say that the crankshaft could be a potential hazard for
continuous high load settings as in flying.
Vibration is another issue not too favorable. Weight can also be discussed.

Then what is left is the Mazda rotary that is available and practical.
All that's needs is the conversion for aircraft use. That's where you
come in.

Regarding any "other" engines there simply are none. Period.

Besides, the vast amount of R&D that has gone into the Wankel engine by
Mazda can not by duplicated overnight by any other engine development.
As stated above, there are no other alternatives around that can be
bought, successfully used and that have a track record.
That is always your way our of any proposal that might be mentioned.

Just set 5 Minutes aside at the outset of you presentation covering ALL
alternative engines.
Also, I trust that Pat had only the Rotary in mind anyway.
