Abstract: A cooling system for a turbine engine is provided. The turbine engine includes a compressor, a compressor discharge chamber (CDC), a combustor assembly, and a turbine coupled in a serial flow relationship such that a first portion of air from the CDC is channeled to the combustor assembly. The turbine is coupled to the compressor via a rotor. The cooling system includes an air duct configured to channel a second portion of air from the CDC to a mid-rotor region of the rotor, and a fluid supply system coupled to the air duct at a coupling. The fluid supply system is configured to channel a flow of fluid to the coupling. The coupling is configured to cool the second portion of CDC air via absorption of heat by the fluid from the second portion of CDC air.

Abstract: A bearing housing configured to enclose a bearing assembly rotatable supporting a shaft coupled to a rotating assembly of a turbine engine, may include a housing base and a housing cover each including a flange for coupling the housing base to the housing cover. The housing cover may include an inner shell and an outer shell radially spaced outward of the inner shell to provide a cavity therebetween. The bearing housing may include a plurality of outlets arranged along an outer surface of the inner shell and configured to spray the pressurized cooling fluid to an inner surface of the housing cover defining the cavity. At least one of the outlets may be configured to spray the pressurized cooling fluid to a region of the inner surface of the housing cover that is adjacent to the flange of the housing cover.
