초록

A foil bearing assembly for use in a gas turbine engine is provided. The assembly includes an annular bearing carrier mounted to the housing of the engine. An annular foil carrier disposed within the bearing carrier and carrying a plurality of overlapping foils that engage an outer surface of a journal. The journal is mounted to the rotating assembly of the engine to define a cavity. Disposed in the cavity is a showerhead having an inlet for receiving a flow of cooling air and a plurality of orifices for providing impingement cooling of the inner surface...
