BA asks me -
You sure you don't mean laminar airfoil and turbocharging barit? I know the answer to that one.
Well, OK, I misspoke.
And offhand, I DON'T know the answer.
bearfoil:
You have a couple different engines/systems confused.
A "baseline" supercharger is a centrifugal compressor, gear-driven from the crankshaft, at perhaps 10:1 drive speed.
A turbosupercharger uses exhaust gases to turn a turbine and thus a centrifugal compressor. It's mechanically separate from the engine, and has been used on many installations including the P&W Wasp Major R-4360 "corncob". But that was NOT the Connie engine.
The Super Connie (and DC-7) used the unique Wright Turbo Compound engine, with exhaust-driven power recovery turbines (3 of them, each fed from six cylinders) geared into the crankshaft to send more "free" horsepower to the engine, gear-driven supercharger, and prop.
