Abstract: A fan rotor blade extending radially from a hub is described. The fan rotor blade may include first surface and a second surface, where the first surface and second surfaces are respectively defined by a set of X-coordinates, Y-coordinates and Z-coordinates. The X, Y and Z coordinates can be set out in any of Tables T-1, T-2, E-1, and E-2. The X, Y, and Z-coordinates can also be scaled by a predetermined factor, with the X-coordinates are oriented in a tangential direction, the Z-coordinates are oriented in an axial direction, and the Y-coordinates are oriented in a radial direction.

Abstract: A support bracket has a support portion, a first mounting portion, and a second mounting portion. The first mounting portion extends from a first end of the support portion. The second mounting portion extends from a second end of the support portion. The second mounting portion defines a coupling hole that is disposed proximate an end surface of the second mounting portion. A first support rib engages a first surface of the support portion and a third surface of the first mounting portion.

The annular body includes a nozzle side and a thrust bearing side. The nozzle side includes a nozzle region proximate the outer rim and a turbine rotor region proximate the main bore, where the outer rim has an outer diameter. The thrust plate assembly also includes a main bore seal installed in the main bore. The main bore seal has an inner diameter, where a ratio of the outer diameter of the outer rim to the inner diameter of the main bore seal is between 3.94 and 3.96.

Abstract: Disclosed is a bearing sleeve for supporting a shaft of an air cycle machine. The bearing sleeve includes an outer diameter and an inner diameter. The outer diameter is within a range of 3.222 and 3.224 inches. Further included is a foil retaining cavity provided in the inner diameter of the sleeve. The foil retaining cavity includes a slot and first and second openings located at opposing axial ends of the slot. Each of the first and second openings include a small portion and a large portion having different axial lengths. A ratio of the combined axial lengths of the large portions to an axial length of the foil retaining cavity is within a range of 0.19:1 and 0.22:1.
