Abstract: A combustion section defines an axial direction, a radial direction, and a circumferential direction. The combustion section includes a casing that defines a diffusion chamber. A combustion liner is disposed within the diffusion chamber and defines a combustion chamber. The combustion liner is spaced apart from the casing such that a passageway is defined between the combustion liner and the casing. A fuel cell assembly is disposed in the passageway. The fuel cell assembly includes a fuel cell that extends between an inlet end and an outlet end. The inlet end receives a flow of air and fuel and the outlet end provides output products to the combustion chamber. The fuel cell extends at an angle between the inlet end and the outlet end relative to a radial projection line.

Abstract: This present disclosure generally relates to systems and methods of electrophoretic deposition (EPD) techniques for use in insulation systems at least partially encapsulating a semiconductor device, a conductive component and a substrate, such as insulation systems of semiconductor devices, busbars, or the like. Insulation systems formed using EPD processes may be designed to have a dielectric constant that decreases in a direction away from a substrate of the insulation system. This may improve insulation technologies since depositing coatings with sequentially arranged dielectric constants may improve resistance of the insulation system to high temperature, high electric fields, or the like.

Abstract: An electric machine includes a rotor assembly having a rotor core that extends in an axial direction and a stator assembly surrounding and coaxial with the rotor assembly. The stator assembly includes a stator core having slots extending in a radial direction into an inner surface of the stator core and extending axially from a first end surface to a second end surface of the stator core. The stator assembly includes stator coil windings disposed within the respective slots of the stator core and a first electrically insulating conformal coating disposed between the stator core and the stator coil windings. The conformal coating includes a polymer matrix impregnated with an effective amount of thermally conductive ceramic materials, above a percolation threshold, that form continuous thermal pathways across a thickness of the first coating.

Abstract: A method of forming a coating on a component of an electrical machine is presented. The method includes coating a surface of the component with a ceramic material, via an electrophoretic process, to form a first coating. The method further includes contacting the first coating deposited by the electrophoretic process with a polymeric material to form a second coating. The method furthermore includes curing or melting the polymeric material in the second coating to form the coating including the ceramic material dispersed in a polymer matrix.
