Abstract: A compressor includes a housing and a mixed-flow rotor mounted within the housing. The mixed-flow rotor includes a blade and a rotor hub with an interior flow passage. The blade includes an internal channel between a pressure surface and a suction surface of the blade. The internal channel extends radially within the blade and is in fluidic communication with the interior flow passage. The blade also includes a plurality of air outlets formed on the blade proximate a leading edge of the blade. The plurality of air outlets extends into the blade to fluidically connect with the internal channel.

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: A heat exchanger includes a heat exchanger core, a pressure housing, and a flex beam. The pressure housing at least partially defines a core chamber. The flex beam extends between and connects the heat exchanger core and the pressure housing such that the heat exchanger core is suspended away from the pressure housing within the core chamber by the flex beam. The flex beam includes a core end connected to the heat exchanger core and a housing end spaced along the flex beam from the core end and connected to the pressure housing.

Abstract: An air cycle machine includes an outer housing, a first section arranged within the outer housing, and a second section arranged within the outer housing and operably coupled to the first section. The first section includes a first housing and a first rotatable component and the second section includes a second housing and a second rotatable component. At least a portion of a fluid flow path extending between an outlet of the first rotatable component and an inlet of the second rotatable component is arranged within the outer housing.

Abstract: The present disclosure provides for heat exchanger assemblies, systems and methods. More particularly, the present disclosure provides for radially-flowing cross flow heat exchanger assemblies and systems that increase primary heat transfer surface, and related methods of use. The present disclosure provides for a cross-flow heat exchanger assembly that can be packaged cylindrically or the like (or other self-enclosed shapes), and where the heat exchanger assembly also increases and/or maximizes primary heat transfer surface area by utilizing a weave-style or interwoven heat exchanger core. A first circuit flow path can be axial or circumferential in nature, and a second circuit flow path can be radial.
