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 sealing system for a rotary machine is provided. The sealing system includes a pair of circumferentially-adjacent rotary components and an axial seal. Each of the rotary components includes a platform including a first side channel and an opposite second side channel, a shank extending radially inwardly from the platform, and a dovetail region extending radially inwardly from the shank. The axial seal is sized and shaped to be received in the first side channel of a first of the rotary components and the second side channel of a second of the rotary components, such that the axial seal sealingly interfaces with the first and second channels.

Abstract: A gas turbine casing with an internal heat exchange system. The gas turbine extends between an inlet section and an exhaust section and defines a downstream direction from the inlet section to the exhaust section. The casing includes a forward end, an aft end downstream of the forward end, a first exterior surface facing radially outward, a second exterior surface facing radially inward, and an internal body at least partially defined between the first exterior surface and the second exterior surface. The heat exchange system includes an inlet and an outlet formed in an exterior surface of the casing proximate the aft end, a supply bore extending upstream from the inlet through the interior body of the casing, and a return bore extending downstream to the outlet through the interior body of the casing.
