초록

A rotating group for a microturbine power generation system includes an electrical generator rotor, a turbine and a compressor intermediate the generator and the turbine. The turbine, compressor and electrical generator rotor are secured together by a tieshaft. The tieshaft is prestressed such that faces of the turbine, electrical generator rotor and compressor maintain contact during high-speed, high-temperature operation of the system.
