Abstract: A heat exchanger includes a body defining a flow channel, and a pin extending across the flow channel, the pin including an at least partially non-cylindrical shape. The pin can be a double helix pin including two spiral branches defining a double helix shape. The two branches can include a uniform winding radius. The two branches include a non-uniform winding radius. The non-uniform winding radius can include a base radius and a midpoint radius, wherein the midpoint radius is smaller than the base radius. The two branches can be joined together by one or more cross-members.

Abstract: A method of manufacturing a rotor of an electric motor or an electric generator includes positioning a plurality of amortisseur bars and using additive manufacturing to place electrically conductive material. More specifically, positioning the amortisseur bars may include circumferentially positioning the bars around a rotor stack and using additive manufacturing to place electrically conductive material may include forming a non-solid pattern of electrically conductive material, such as a pattern of electrically conductive traces, across opposite axial ends of the rotor stack to electrically interconnect an amortisseur circuit.

Abstract: A conductor assembly can include one or more conductors formed by a conductive material, and one or more filter cores formed integrally on and at least partially around the one or more conductors. The one or more filter cores can be formed of a material different than the conductive material and can be configured to reduce electromagnetic emissions from the one or more conductors.

Abstract: An assembly and a method for manufacturing an assembly for transmitting torque to an aircraft actuator. The assembly and method include a torque tube having a longitudinal axis and an end fitting. The ending fitting includes a connector portion and an engagement portion that is inserted into the torque tube. The engagement portion includes a first end adjacent the connector portion, a second end opposite the first end, and a coupling region between the first and second end that includes an outer coupling surface having an outer diameter and a continuous groove formed thereon. The continuous groove includes two axial grooves that extend along the outer coupling surface along the longitudinal axis and a first parallel groove that extends circumferentially about the longitudinal axis along the outer coupling surface that joins the two axial grooves.

Abstract: An additive manufactured workpiece includes one or more cavities having an inner surface. A dielectric interface is formed in the cavity, and conforms to the inner surface. The additive manufactured workpiece further includes an in-situ electrode in the cavities. The dielectric interface is interposed between the in-situ electrode and the inner surface of the workpiece.

Abstract: A method of improving an internal surface topography of a manufactured workpiece includes filling a workpiece with an electrically conductive magnetorheological (MR) fluid. The workpiece includes at least one internal feature having an inner surface with at least one irregularity. The method further includes converting the MR fluid into a rigid MR material, applying a voltage to the rigid MR material, and ablating the inner surface in response to the voltage to remove the at least one irregularity.
