  • Assembly and method for cooling rear bearing and exhaust frame of gas turbine
    Patent number: 7493769
    Abstract: A propeller is mounted aft of the rear rotor supporting bearing of a gas turbine. The propeller is driven either by the rotor shaft or by the exhaust gases flowing through the exhaust frame of the turbine. The rotating propeller blows cooling air on the rear bearing. The cooling air can then be circulated through the exhaust frame to cool the exhaust frame as well.
