 This is the first I've seen of  this engine.  I think the three shafts are
 geared together with those big, straight cut spur gears seen in one of the
 photos.  If it works, it would be an interesting thing to put in a P-51
 airframe.

 Steve,
        No idea about HP and torque ?  Thanks, EB.


 I'm guessing on the order of 2000hp or more, depending on how hard you want
 to push it.  The article also says it fits a 30 inch cube; very compact!.
 How much horsepower do you think a four rotor engine times three would
 make?
 According to the article it uses 13B rotors--12 of them!

 700 HP times three is 2100 HP non turbo charged.

 A turbo compound version might rival a R 3350 TC without
 the exhaust valve problem.

Did you say 30 inch cube?  Where can I get two of them...

What would the horsepower go to with turbo compounding, 2800 hp ?

Question, any chance that an output shaft can be run along the top of the
engine to allow a tractor and pusher configuration much like the Cessna
Skymaster 337 ?

Well, they do say that every advance in aviation came about following
an advance in engine technology!
