The standard prefixes already in piston engines for aviation is:

GTIR-80-A1B

G = Geared
T = Turbocharged
I = Injected
R = Rotary [or radial]
80 = cubic capacity of the engine
A1B = the configuration of the engine, including HP, Fuel Type, Accessories
etc as per a spec sheet. One spec sheet per aircraft installation.
An A1B might be 230hp for the RV-4, an A2B might be a 200hp for the Eagle
etc.

A supercharged 3 rotor would be:
GSIR-120-A1B
Everyone already in aviation would understand this.

Shouldn't there be an "L" in there somewhere (liquid-cooled).

Russell Kent

Right.

Paul Lamar

I believe that "L" usually refers to left hand rotation.
"W" is sometimes used to represent the less accurate "Water-cooled"

The latest Continental liquid cooled engines are IOL 200's or IOL-300's.

BTW as a side the X designation was given to a double V12
as in Allison X-3420.
