this is irrelevant. sorry

Very true if you want to go on the world market of mfg's. Ah yes only one compressor or turbine section, as far as I know they all only one of each, I might be wrong but never came across one. We were talking about stages of compression and stages on the turbines not sections. Thanks and your right they have been used in APU's, TurboProp aircraft, helicoptors and even tried in cars and trucks, and one time at Indy but outlawed. Joe Lennerd (sp) lead the entire race only to shut down on the last lap to lose with a turbine powered car.

oh stages, i thought you were talking about sections (# of shafts) well i know of a few APU's that use a centrifugal compressor with one turbine section . i rebuilt one that had a two stage centrifugal comp with only one turbine stage. there was only one compressor wheel but it had blades on both sides.they should use those on centrifugal superchargers.
