    Abstract: In accordance with at least one aspect of this disclosure, a rectifier assembly includes, at least, a first diode disposed between a first bus bar and a second bus bar. The rectifier assembly further includes, a first thermal management structure and a second thermal management structure. The first thermal management structure is configured to electrically connect the first bus bar to the first diode and be in thermal communication between the first bus bar and a first side of the first diode to transfer heat between the first bus bar and the first diode. The first thermal management structure is configured to transfer heat between the first bus bar and the first thermal management structure. The first thermal management structure is also configured to allow a fluid to flow therethrough to transfer heat from the first thermal management structure to the fluid flowing therethrough.

    Abstract: In accordance with at least one aspect of this disclosure, a power distribution system having integrated cooling includes a chassis defining an interior cavity, an electronics bus structure housed within the interior cavity, and an electrical contactor operatively connected to the electronics bus structure to receive a voltage therefrom. One or more heat dissipation fins can be included extending away from the chassis and configured to dissipate heat from the electronics bus structure to an ambient environment external to the chassis. In embodiments, the electronics bus structure can be sealed within the interior cavity.

    Abstract: Disclosed is an cabin air compressor (CAC), having a CAC inlet defining a bleed inlet and has a bleed inlet aperture that circumferentially extends about the CAC inlet to define a bleed inlet forward end and a bleed inlet aft end; and a bleed duct that extends from a bleed duct inlet located at the CAC inlet to a bleed duct outlet located at a CAC motor section and is fluidly connected to the bleed inlet; and a scoop defining a scoop aft end connected to the bleed inlet aft end, and a scoop body extending toward a case forward end of the case to a scoop forward end, wherein the scoop is frustoconical and converges toward the case forward end to provide a radial inlet gap between the scoop forward end and the bleed inlet forward end.

    IPC: H02K5/18 ,  H02K15/14 ,  H02K9/02

    Abstract: An electromechanical actuation motor includes a main housing, a series of stator windings, and a first circumferential row of fins. The series of stator windings is disposed inside of the main housing. The first circumferential row of fins is connected to and extends radially from an outer surface of the main housing. The main housing and the first circumferential row of fins are formed as a single piece of material via layer-by-layer additive manufacturing. Each fin of the first circumferential row of fins includes a first portion and a second portion. The first portion is integrally formed with and attached to the outer surface of the main housing at a first end of the first portion. The second portion is attached to and integrally formed with a second end of the first portion. The first portion intersects the second portion to form a T-shape.
