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 housing of an air cycle machine includes a static seal portion, a main bore housing portion, a shroud pilot housing portion, and a thrust plate housing portion. The static seal portion is arranged about a central axis and defines static seal radius D1. The main bore housing portion is arranged about the central axis and circumscribes the shaft arranged along the central axis. The main bore housing defines central bore inner radius D2. The shroud pilot housing radius is arranged about the central axis and defines shroud pilot radius D3. The thrust plate housing portion is arranged about the central axis and defines insulator seal plate radius D4. A ratio D1/D2 is 0.8394 to 0.8416, a ratio D1/D3 is 0.4315 to 0.4322, a ratio D1/D4 is 0.2517 to 0.2521, a ratio D2/D3 is 0.5130 to 0.5146, a ratio D2/D4 is 0.2993-0.3001, and a ratio D3/D4 is 0.5828-0.5838.

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. Further included is a seal attachment portion provided at one axial end of the bearing sleeve configured to circumferentially support a seal.
