    Abstract: A fan housing for an air cycle machine includes a fan exit flow passage and a ring disposed around a center axis of the fan housing and disposed around the fan exit flow passage. The ring includes a first end disposed axially opposite a second end and a guide surface facing radially inward relative the center axis and formed between the first end and the second end. The ring also includes a shelf disposed radially inward from the guide surface. The shelf includes a stop surface extending radially and disposed axially between the second end and the guide surface. The shelf also includes a shelf surface facing radially outward relative the center axis and extending axially between the first end and the stop surface.

    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 support bracket includes a body, an arm, a first mount, a boss, and a second mount. The arm extends laterally from the body and a first fastener opening passes through the arm. The first mount extends from a first side of the body, and a first fillet is disposed at the interface of the first mount and the body. A boss extends from a second side of the body and a second fastener opening passes through the boss. A second fillet is disposed at the interface of the boss and the body. The second mount extends into the body opposite the boss. A third fillet is disposed at the interface of the second mount and the first side and a fourth fillet is disposed at the interface of the second mount and the second side.

    Abstract: An air cycle machine has a housing which holds a compressor section, and a turbine section having an expansion area, and a fan section disposed outside of the housing. A shaft, which attaches to and is coaxial with the compressor section, the turbine section and the fan section, is supported by an air journal bearing and an air thrust bearing. The shaft has a hollow core for porting cooling air from the air journal bearing and the air thrust bearing, and a tube that extends into said expansion area and communicates cooling air from the turbine expansion area to the thrust bearing.
