Paul - A somewhat frivolous question, prompted by the PSRU question.
With the planetary reversing rotation, has anyone considered reversing the
rotation of a Wankel engine to broaden the propeller selection base?.
This is a common gambit with V8s and single stage gear reductions.

Vance, I AM surprised. I thought I had you thoroughly trained on the intricacies of
the Wankel engine. You must realize by now, unlike a silly two cycle piston engine,
IT WILL NOT RUN BACKWARDS gracefully !!!! :-)

Is there enough attitudes in that paragraph for you? :-)

Not to worry folks. Vance and I are local good friends.

Not unless the exhaust port becomes the intake port and vice versa. Then the port
timing would be way off as would the cooling of the rotor housing.

Just to continue this pointless aside :-)
It seems like it would be less of an engineering challenge to drive the PSRU from the
front end (anti-flywheel end).  Then your prop rotation is reversed and the engine is
still running forwards.

The big problem there is the shaft is smaller diameter coming out the front
least someone thinks this might be a good idea.
