Abstract: A rotating shaft for a rotary machine includes a first shaft portion centered on a central axis and a variable lattice structure in an interior of the rotating shaft. The variable lattice structure includes a first region of the rotating shaft having a first lattice structure and a second region of the rotating shaft having a second lattice structure. The second lattice structure of the second region is denser than the first lattice structure of the first region. The second region is a deflection region or a stress region of the rotating shaft.

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: A turbine inlet supplies compressed air to drive a turbine impeller. There is a compressor impeller and a compressor inlet connected to supply air to be compressed to the compressor impeller. The compressor impeller delivers air to a compressor outlet. The compressor outlet is connected to the turbine inlet. A turbine outlet is connected to a first connection connected to an aircraft. The turbine impeller is connected to the compressor impeller by a drive shaft including a radially outwardly extending thrust disk, and thrust bearings provided on each side of the thrust disk. A cooling air inlet is connected to pass air along the thrust bearings, then radially inwardly and then axially along the shaft. The cooling air is directed to a cooling air outlet. The cooling air outlet is connected to a second connection maintained separate from the first connection. An environmental control system is also disclosed.

Abstract: A machine for use in an environmental control system has a turbine impeller. A turbine inlet is connected to supply compressed air to drive the turbine impeller. There is a compressor impeller and a compressor inlet connected to supply air to be compressed to the compressor impeller. The compressor impeller delivers air to a compressor outlet. The compressor outlet is connected to the turbine inlet. A turbine outlet is connected to a first connection connected to an aircraft. The turbine impeller is connected to the compressor impeller by a drive shaft. The drive shaft includes a radially outwardly extending thrust disk, and thrust bearings provided on each of two axial sides of the thrust disk. A cooling air inlet is connected to pass air along the thrust bearings, then radially inwardly and then axially along the shaft. The cooling air is directed to a cooling air outlet. The cooling air outlet is connected to a second connection maintained separate from the first connection. An environmental control system is also disclosed.

Abstract: A motor housing assembly for a cabin air compressor assembly is provided that includes a central body portion, a first end portion, and a second end portion. The central body portion has an internal cavity configured to receive an electric motor. The first end portion includes a first and second motor cooling inlet duct. The second end portion includes a flange configured to couple with an outlet housing of the cabin air compressor assembly. A motor cooling duct centerline is defined between the first and second motor cooling inlet duct and is perpendicular to a central body portion centerline. A first distance is defined between an outer edge of the first and second motor cooling inlet duct. A second distance is defined between an outer face of the flange and an intersection of the centerlines. A ratio of the first distance to the second distance is between 1.29 and 1.3.
