Claim 5:
6. The method according to claim 1, wherein the compressor rotor shaft assembly defines a pressurized cavity therewithin that is in fluid communication with the pressurized air source, and the plurality of pressurized airflow nozzles are arranged through at least one rotor shaft section of the compressor rotor shaft assembly, the plurality of pressurized airflow nozzles being circumferentially spaced apart and arranged to provide a tangential flow of air therefrom, with respect to a circumferential direction about the compressor rotor shaft assembly, and, in the directing, the plurality of pressurized airflow nozzles direct the flow of pressurized air therefrom in a tangential direction into the compressor flow passage so as to cause the compressor rotor shaft assembly to rotate.
