Paul,

I'm sorry if this question has been asked before....
Could a Wankel engine be designed that would work without a PS RU in a
light aircraft?

Best Regards,
Andy Abreu

Not likely. It would have to be greatly enlarged and operated at prop
RPM which would totally negate it's current excellent power to weight ratio.

Paul Lamar ...No rotor no motor.

My friend, Vance Jaqua, considered a ducted fan that was direct drive, but
you lose a lot of efficiency.  There is nothing wrong with a properly
designed PSRU.
