Whenst I was an undergrad at Cal Poly San Luis Obispo, the aero department
had a LeRhone. We had it mounted to a trailer so we could run it. The crank
is held stationary and the rest of the engine rotates. Now this thing is
just plain scary when running. I think it was a nine cylinder affair and it
was all a blur when turningover. Fuel air mix was handled through the crank
and it attachment and it used a oil gas mix if I am not mistaken (and I
could very well be, this has been pert near 40 years ago!). I belive this
engine was used in the Sopwith Camel ( now there is a name for an
airplane...). I forget the rotation direction but supposedly the aircraft
was hard to turn one direction because of the gyro effect of all that mass
spinning around. So they killed the engine in busts when making a turn for
landings etc..
mayf, out in Pahrump
