Abstract: Oleophobic and/or oleophilic coatings to reduce heat loads on a gas turbine engine thermal management system are disclosed herein. An example method to reduce heat load in a gas turbine engine includes applying an oleophobic coating to an internal wall of a sump, the sump located in proximity to a heat generating element of the gas turbine engine, and applying an oleophilic coating to the heat generating element of the gas turbine engine, the heat generating element positioned in a cavity of the sump.

Abstract: Bearing assemblies for a turbomachine include a first race statically coupled to a fixed engine housing, a second race coupled to a rotating shaft, a bearing cage disposed between the first race and the second race, and at least one bearing element disposed in the bearing cage. The bearing cage can include inlet channels to allow air to flow into the bearing cage and outlet channels that allow the air and lubricant mixture in the bearing cage to vent into adjacent compartments of the turbomachine. During operation, the inlet channels actively direct an airflow into the bearing cage. In the bearing cage, the air mixes with lubricant, and the air and lubricant mixture is expelled from the bearing cage through the outlet channels, thereby reducing dwell time of lubricant in the bearing assembly.

Abstract: A bearing assembly includes a bearing, an outer race located radially outward of the bearing and supporting the bearing, a bearing housing located radially outward of the outer race and supporting the bearing and the outer race, and a bearing lubricant drain including a multi-directional passage formed in one or both of the outer race or the bearing housing, the lubricant drain arranged to cause a lubricant to flow from a first location to a second location. The second location is radially outward and axially offset from the first location. A gas turbine engine includes a shaft configured to rotate about a centerline axis of the gas turbine engine and the bearing assembly configured to facilitate the rotation of the shaft.
