Abstract: A sensor supply tube assembly is provided for disposition within a compressor outlet through which a main flowpath is defined and a sensor port transversely coupled to the compressor outlet. The sensor supply tube assembly includes first and second tubes. The first tube is formed to direct main flowpath fluid from the compressor outlet and through a portion of the sensor port and includes first and second ends disposed within the sensor port and the compressor outlet, respectively, and a curved section interposed between the first and second ends. The second tube includes a sleeve tightly fittable between the first end and the sensor port and a base. The base has an exterior surface from which the sleeve extends and which is disposed and configured to non-rotatably abut with an interior surface of the compressor outlet.

Abstract: A method for repairing a turbine housing of an air cycle machine that includes removing damaged material from a journal bearing bore of the turbine housing and forming the journal bearing bore. Next, the inner diameter of the journal bearing bore is determined and a cylindrical insert is formed. The cylindrical insert includes a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The second end of the cylindrical insert is inserted into an inlet of the journal bearing bore up to the step. The cylindrical insert is secured to the turbine housing and both are stress relieved by heating. Following the stress relief, the inner surface of the cylindrical insert is formed and seal grooves are formed on the inner surface.

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: An air cycle machine comprises rotating components that include a fan, a compressor, and a first turbine. The air cycle machine also includes a cooling airflow path that receives cooling air from a cooling air source, directs the cooling air to an air-cooled bearing for at least one of the rotating components, and discharges the cooling air. The airflow path is isolated from an inlet of the compressor by a seal member, and the airflow path is configured to maintain pressure at the seal member above a pressure at the compressor inlet.

Abstract: An annular backing plate for a diffuser in a centrifugal compressor comprises an inner diameter and an outer diameter disposed radially opposite the inner diameter. The backing plate also includes a first surface extending between the inner diameter and the outer diameter of the backing plate. A step is formed on the first surface proximate the inner diameter, wherein the step shifts a portion of the first surface encompassed by the step axially aft relative a portion of the first surface not encompassed by the step.

Abstract: A method for repairing a turbine housing of an air cycle machine is provided. The method comprises: removing damaged material from a journal bearing bore of the turbine housing; forming the journal bearing bore to an inner diameter of about 2.580±0.001 inches (6.553±0.003 centimeters). The journal bearing bore having an inlet and an outlet. The method also comprises determining the inner diameter of the journal bearing bore; and forming a cylindrical insert having a first end, a second end, an inner surface, a step located at the first end, and an outer surface with an outer diameter that provides a diametric interference with the inner diameter of the journal bearing bore. The diametric interference being between about 0.000-0.003 inches (0.000-0.008 centimeters). The method further comprises inserting the second end of the cylindrical insert into the inlet of the journal bearing bore up to the step.
