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.

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.

Abstract: An annular water removal system (AWRS) for an air cycle environmental control system (ECS) includes a line replaceable unit (LRU) configured to output air flow, and a water collector coupled to the LRU. The water collector includes an upper portion and a lower portion. The upper portion includes a coalescing unit having a collector inlet to receive the air flow and configured to coalesce moisture from the air flow output from the LRU. The lower portion includes a collection unit in fluid communication with the coalescing unit. The collection unit is configured to collect the moisture coalesced by the coalescing unit.
