NON-CONTACTING SEALS FOR GEARED GAS TURBINE ENGINE BEARING COMPARTMENTS |
摘要 |
A rotating element is associated with at least one bearing compartment that includes a bearing to support the rotating element. A seal resists leakage of lubricant outwardly of the bearing compartment and allows air to flow from a chamber across the seal and into the bearing compartment. The seal has a seal face facing a rotating face rotating with the rotating element. The seal is a non-contact seal. A gas turbine engine is also disclosed. |
