Zusammenfassung: | PROBLEM TO BE SOLVED: To manage the temperature gradient of a turbine system.SOLUTION: A temperature gradient management arrangement for a turbine system includes a rotor 18 comprising a rotor bore 36 extending axially along the rotor 32. Also included is a secondary flow path 56 comprising an inlet for a secondary airflow 52 to flow to the rotor bore 36 and an outlet 58 disposed axially upstream of the inlet, relative to a main flow direction of the turbine system. Further included is a flow rate manipulator 62 disposed proximately to the outlet 58 and configured to increase a flow rate of the secondary airflow 56 during a first turbine system operating condition and to decrease the flow rate of the secondary airflow 56 during a second turbine system operating condition. |
