摘要： An example fan assembly impeller moves air along a secondary flow path when driven by a motor. The motor also drives a fan rotor to move air along a primary flow path of the fan assembly. Air moving along the primary flow path moves in a first direction. Air moving along the secondary flow path moves in a second direction opposite the first direction. An example fan shroud communicates air used to cool a motor into a primary flow path of a fan assembly. The shroud communicates the air into the primary flow path so that the flow of air is at least partially aligned with air moving through the primary flow path of the fan assembly.

摘要： An air cycle machine including a housing with a compressor housing portion and a turbine housing portion secured to one another by fasteners. The compressor and turbine housing portions each provide a surface. An insulator plate is provided between and engages the surfaces. The fasteners extend through circumferentially arranged holes in the insulator plate. The insulator plate has an axial width, an inner diameter and an outer diameter. The outer diameter to the inner diameter provides a first ratio of 1.19-1.21, and the inner diameter to the width provides a second ratio of 53-59. In one example, the insulator plate is a composite structure constructed from 9-12 carbon fiber laminations with each layer having directional carbon fibers oriented transversely relative to the carbon fibers of an adjacent layer.

摘要： An air bearing for a ram air fan includes a shaft having a first end portion that defines a cap end, a second end portion that defines a thrust shaft receiving end, and an intermediate portion extending between the first and second end portions. The cap end includes a cap pilot bore and the thrust shaft receiving end includes a thrust shaft pilot section. The thrust shaft pilot section has an outer diameter of between about 1.6032-inches (about 40.7212 mm) and about 1.6002-inches (about 40.6450 mm).

摘要： 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.

摘要： An improved staggered seal assembly uses a static element and a rotating element to create a seal. The static element surrounds the rotating element and has at least one fin. The rotating element has at least one long fin and a set of shorter fins. A third component has a staggered fin. The fins create a leakage flow path which throttles the leakage across the seal from a high pressure zone into a low pressure zone.
