Abstract:
The present disclosure is directed to a bearing assembly for a gas turbine engine. The bearing assembly includes a bearing housing and a bearing pad for supporting a rotary component of the gas turbine engine. The bearing pad includes at least one gas inlet and a plurality of gas outlets configured on an inner surface thereof. The gas inlet is in fluid communication with the plurality of gas outlets via a gas distribution labyrinth. Further, the gas distribution labyrinth includes a plurality of passageways configured to evenly distribute pressurized gas entering the gas inlet to an interface between the inner surface of the bearing pad and an outer diameter of the rotary component.
