Paul - and others
Many people have proposed that it would be very
advantageous to couple the powe out put of a Wankel
directly to the rotor for quieter and potentially
more efficient propeller speed without a PSRU.
This is structurally posible, but not very elegant
by using U jointed drive shaft coupling. The
eccentric would probably still be required to
control the rotor path. 

 Now - what would the
displacement be? in that the output shaft is now
one to one with the rotor, and is even more directly
connected to the device which is pumping the air,
and extracting power during expansion ?

I don't wish to speculate because I can think of no
worse way to ruin the elegant simplicity of the Wankel 
rotary engine :-) PL
