Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a cooling circuit serving to provide cooling air in a rotor having a compressor rotor (12) and a turbine rotor (14). SOLUTION: The cooling circuit includes a first cooling path (18) through the compressor rotor in series with a second cooling path (24) through the turbine rotor such that one amount of cooling air is used for cooling both the compressor rotor and the turbine rotor. The construction enables reduction in cooling air requirements, thereby increasing power plant efficiency. COPYRIGHT: (C)2010,JPO&INPIT
