Gas turbine power plant
An automotive power plant includes three turbine rotors, of which one forms a spool together with the compressor, and the other two rotors are interconnected by a gearing. The first turbine rotor is undersized, and cannot provide the necessary power for driving the compressor at full load, although the spool does not have to drive any internal auxiliaries. A slim shaft, carried in air bearings and rotating at supercritical speed, also when the plant is idling, transfers power from the gearing to the compressor spool. The turbine casing is die-cast of a light metal alloy, and is internally clad with pre-formed ceramic insulation components, bonded to the metal walls. In a front drive vehicle the casing is mounted in arcuate guides having their centers at the vehicle wheel axles, whereby the casing may be swung about 90/sup 0/, when the gas turbine is to be serviced.
