Abstract: A turbine housing includes a turbine inlet plenum and a turbine housing body. The turbine housing body includes a turbine outlet mounting face, a seal plate mounting face, and a center bore formed between the turbine outlet mounting face and the seal plate mounting face. A first support is formed about the turbine inlet plenum and in contact with the turbine housing body. A relief pocket is formed in the first support proximate the seal plate mounting face. The relief pocket is formed at a first distance from a turbine housing center axis of the center bore and at a first depth relative to the seal plate mounting face. A ratio of the first distance to the first depth is between 2.66 and 2.90.

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: A ram air fan has a fan impeller and a motor. The impeller and motor are mounted within a housing. An inlet header delivers air to an inlet for the fan. An air supply system delivers air from an internal cavity of the inlet header to the motor and air bearings. The air supply system includes a conduit extending through the housing. A connection from the conduit extends from a J-shaped tube mounted within the inlet header. The J-shaped tube extends to a remote end, with a perforated member positioned on the remote end.

Abstract: A shaft for a cabin air compressor includes a first attachment portion, a second attachment portion, an intermediate portion, a retention flange, and a tie rod support pocket. The first attachment portion is disposed at a first end of the shaft. The second attachment portion is disposed at a second end of the shaft opposite the first end. The intermediate portion extends from the first attachment portion to the second attachment portion and an interior wall of the intermediate portion defines an inner shaft space. The retention flange extends a first distance into the inner shaft space from the interior wall of the intermediate portion and is offset from the first attachment portion by a second distance. The tie rod support pocket is defined by the interior wall, extends between the flange and the first attachment portion, and is configured to receive a tie rod support.

Abstract: An air cycle machine includes a housing having an exterior wall and an interior wall, a scavenging turbine supported for rotation within the housing, and an ambient air fan. The ambient air fan is supported for rotation within the housing and is operably associated with the scavenging turbine. The interior wall defines therethrough a turbine-fan port that fluidly couples the ambient air fan to the scavenging turbine for communication of an overboard air flow to an ambient air flow without external ducting. Environmental control systems and methods of flowing fluid through air cycle machines are also described.

Abstract: An air cycle machine is provided including a plurality of components operably coupled via a shaft, the shaft being rotatable about an axis. A cooling airflow path receives cooling air from a cooling air source, directs the cooling air to at least one air-cooled bearing associated with one of the plurality of components, and discharges the cooling air. A cooling conduit is arranged in fluid communication with the cooling airflow path, wherein cooling air provided to the cooling conduit from the cooling airflow path has a first temperature and cooling air returned to the cooling airflow path has a second temperature, the second temperature being less than the first temperature.
