I don't think Jim ever considered making them with the steel wear plate.
that was my idea. At least I think it was my idea. One can never be sure
unless one searches the patent office.

I think it would be ideal for a one rotor as one rotors have power to

weight

ratio problems due to extreme over design of end housings designed for
two rotor engines. Obviously you are thinking about that :-)

Bruce -Hope you do!!

Paul-see the new Radial engine to come out of Brisbane
I call it a Radial Rotary as it has only 3 spark plugs and the cylinders
rotate
around to them anticlockwise while the drive shaft rotates clockwise.
A simple light weight(water cooled) motor 100hp@3,000rpm Direct drive
and130hp@ 6,500 rpm with a PSRU.(nothing stunning there in the power output)
However a very simple motor.
Inventor claims that because of the simplicity of the engine, anyone can
pull it down in
a short time -also can be built in banks of 3 and 5 cylinders ie. stacked in
series.
Oh yes! - there are no valves.

Bill,
My engineer mate said his new engine was a lot simpler a true aircooled
rotary - I know I'm still waiting too !!
George (down under)

Good luck to him George. The patent office is full or rotary engines
like this. BTW IBM has a online patent search web site as I recall.

Right off the bat I see no provision for cooling the cylinders.
The other major problem I see right now is sealing the combustion chamber.
Nothing that a billion dollars and 30 years development cannot solve however :-)
