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.

Abstract: A compressor includes a purge flow extraction path extending radially and configured to direct an airflow radially inwardly. Also included is a center bore at least partially defined by a rotor structure extending axially and fluidly coupled to the purge flow extraction path. Further included is an airflow manipulation device disposed entirely within the center bore, the airflow manipulation device having a plurality of vanes defining at least one vane slot.
