  • Patent number: 5720558
    Abstract: A tilting bearing pad for use in a turbine engine in accordance with the present invention includes an opening extending between opposing inner and outer surfaces of the pad and a profiled area extending from the opening. More specifically, the opening comprises a feed hole which extends from the outer surface toward the inner surface of the pad and is connected to an axial feed groove which extends to and along the inner surface. The profiled area extends from one side of the axial feed groove towards the trailing edge of the bearing pad along the inner surface. The side of the profiled area facing the trailing edge of the pad may be squared or tapered. The side of the axial feed groove facing the leading edge remains substantially flush with the groove and does not extend towards the leading edge. A turbine engine with the tilting bearing pad as described above also includes two bearing cases, a rotor, and a fluid supply system. The bearing cases are located at opposing ends of the turbine case.
