  • Oil Scavenge System for a Gas Turbine Engine
    Publication number: 20080134657
    Abstract: An oil scavenge system includes a scavenge pipe which extends forward into a relatively long and narrow compartment area of a rear bearing compartment of a gas turbine engine with aggressive core size constraints. The scavenger pipe communicates collected oil to a scavenger pump to return oil to the oil sump and evacuate the oil before flooding of the seals may occur.

  • Radially energized oil capture device for a geared turbofan
    Publication number: 20080107522
    Abstract: A turbine engine utilizes an oil director to direct any leakage oil from a rear bearing compartment of the turbine engine toward a drain opening for an oil drain. The oil drain is formed in a heat shield located between the low pressure turbine and the exhaust nozzle. The oil drain directs the leakage oil to a benign area of the turbine engine.
