    摘要: A contact seal assembly for a shaft of a gas turbine engine includes a seal runner adapted to be connected to the shaft and rotatable relative to a carbon ring. The seal runner includes concentric inner and outer annular portions radially spaced apart to define at least one internal fluid passage between the inner and outer annular portions of the seal runner.

    摘要: The method for testing the integrity of a seal of a cavity in an engine includes providing a sealed test tank external to the cavity, the test tank having an internal volume that is particularly selected, as described herein. A pressure differential is generated between the test tank and the cavity, by creating an initial test pressure within the test tank that is different than an ambient pressure inside the cavity. Gas flow between the test tank and the cavity is then permitted, and a change in pressure within the test tank is measured, as is a test time required for the pressure inside the test tank to reach a reference pressure. The measured test time is compared with a predetermined reference time, and the integrity of the seal may be confirmed when the test time is greater than or equal to the reference time.
