Abstract: A lubrication system for a turbine engine having one or more rotating components. The lubrication system includes a primary reservoir that stores a lubricant therein. A primary lubrication system supplies the lubricant from the primary reservoir to the one or more rotating components during normal operation of the turbine engine. An auxiliary lubrication system includes an auxiliary reservoir in fluid communication with the primary reservoir and the one or more rotating components. The auxiliary reservoir receives the lubricant from the primary reservoir and is positioned at substantially a six o'clock position of the turbine engine. The auxiliary lubrication system supplies the lubricant from the auxiliary reservoir to the one or more rotating components based on at least one of a pressure of the lubricant in the primary lubrication system, a pressure of fuel in the turbine engine, or a pressure of hydraulics of the turbine engine.

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 gas turbine engine including a compressor section for compressing air flowing therethrough to provide a compressed air flow and a reverse flow annular vortex combustor including a combustion chamber having a primary combustion zone, the combustion chamber configured to combust a mixture of a fuel flow and the compressed air flow in the primary combustion zone to generate a primary zone vortex. The reverse flow annular vortex combustor has a combustor liner and one or more driver openings extending through the combustor liner, the one or more driver openings providing a driver air flow formed of the compressed air flow. The driver air flow enters the combustion chamber as a wall of air for shaping and driving the primary zone vortex in the combustion chamber.
