A single gas turbine may be made alternately useable as an auxiliary power unit, a load compressor, an air turbine starter, or an air turbine starter motor by placing a selectively operable clutch 38 between a centrifugal compressor 10 and a turbine wheel 30, by placing a valve 58 in ducting 48, 50, 52, 54 extending from the compressor 10 to a combustor 44, and by providing variable inlet vanes 24 at the inlet 20 to the compressor 10. By appropriate operation of the valve 58, the clutch 38, and the vanes 24, each of the foregoing functions can be obtaine...
A method of operating a gas turbine alternatively as an auxiliary power unit, a load compressor, and air turbine starter or the like, the turbine including a centrifugal compressor and a rotary turbine wheel together with a clutch interconnecting the compressor and the turbine wheel and selectively operable to couple or decouple the compressor, variable inlet guide vanes for the compressor, and a combustor for providing hot gas to the turbine, said method comprising the steps of: (a) operating the gas turbine as an auxiliary power unit by driving the com...
