Subject: Reverse rotation rotary?

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.


Since you are making up all sorts of manifolds, reversing intake to exhaust is no big
deal.
Similar to any other 4 stroke engine there is significant overlap and a high degree of
symmetry in the effective valve timing, such that a minor amount of porting would take
care of any miss timing. The heat issue could be a sinker tho. Just thought I would
wake up the troops, and get the creative juices flowing - Vance :-)
