Abstract: A fuel injector for a turbine engine includes a fuel scheduling valve configured for regulation of fuel flow from a fuel inlet, in response to fuel pressure received at the fuel inlet. Primary, secondary and auxiliary fuel circuits receive fuel from the scheduling valve, and an electrically-controlled valve is provided in fluid communication with the auxiliary circuit, which electrically-controlled valve is adapted and configured to actively control fuel through the auxiliary circuit in response to a control signal.

Abstract: Disclosed is a method of improving the effectiveness of an oxygen removal unit for a fuel supply system. The method includes contacting a tube bundle with a repair liquid at 20 to 40° C. for less than two hours. The tube bundle includes tubes having an air permeable, non-porous polymer layer with discontinuities. The repair liquid includes a solvent and a curable thermoset material. The curable thermoset material is deposited in the discontinuities of the air permeable, non-porous polymer layer and cured. Also disclosed is a fuel system oxygen removal unit including a tubular bundle formed of tubes having an air permeable, non-porous polymer layer disposed on a microporous support wherein the air permeable, non-porous polymer layer includes discrete segments of a cured thermoset material.

Abstract: A rotary machine includes a shaft extending through the rotary machine; a bearing positioned around the shaft; and an air deflector mounted on the shaft between the bearing and the shaft, wherein the air deflector has a first cylindrical body portion that is connected to a second cylindrical body portion with a ramp portion. A method for cooling a bearing positioned around a rotating shaft includes providing air to a cavity that surrounds a rotating shaft; deflecting the air towards an inner surface of a bearing that is positioned radially outward of the rotating shaft, wherein the air is deflected with an air deflector that is mounted on the rotating shaft; and flowing the air between an outer surface of the air deflector and the inner surface of the bearing.

Abstract: A thrust shaft contains a shaft body having a disk at one axial end to provide a rotating surface in a thrust bearing, the disk having a first side and an opposite second side. The thrust shaft also contains a first section extending from the first side of the disk, the first section cylindrical in shape and having eleven holes uniformly spaced circumferentially about the first section, the holes being substantially axially equidistant from the first side of the disk. The thrust shaft also contains a second section cylindrical in shape having a smaller diameter than the first section, the second section extending from the first section to an end of the shaft remote from the disk.
