Abstract: An electrochemical machining system includes an anodic workpiece of an electrically conductive metal, and an electrically conductive metallic cathodic tool with an external surface configured to machine the anodic workpiece. At least a portion of the external surface of the cathodic tool has a coating of diamond-like carbon (DLC). The system further includes a current source configured to apply a pulsed direct current to the anodic workpiece and the cathodic tool, and an electrolyte between the anodic workpiece and the cathodic tool.

Abstract: An endwall may be disposed at one end of a vane assembly. The endwall may comprise an endwall spar and a coversheet on the hot surface of the endwall spar. The endwall may further comprise a cooling fluid channel between the hot surface of the endwall spar and the cold surface of the coversheet. The cooling fluid channel may include a cooling fluid inlet disposed in the endwall spar, and a cooling fluid outlet. The cooling fluid outlet may be formed at an angle with the axis of the endwall spar. A plurality of pedestals may be disposed on the hot surface of the endwall spar extending into the cooling channel. The pedestals may be formed at an angle with the axis of the endwall spar to direct a cooling fluid.

Abstract: Electric machine drive systems, and related electric machine embodiments, include technologies for providing redundancy of shaft information of one or more electric machines between converter controllers of the corresponding system. The converter controllers are configured to control operation of power converters, which control one or more electric machines. The disclosed technologies include establishing one or more communication buses between the converter controllers to share the shaft information, which may be based on analog signals from a single, common resolver and/or from different, redundant resolvers depending on the embodiment. For example, in some embodiments, converter controllers communicatively connected to the same resolver may include separate resolver-to-digital converters (RDCs) to provide redundancy of the RDCs.

Abstract: A fan assembly includes a fan duct, an inlet fan, and an outlet guide vane assembly. The inlet fan includes blades adapted to force fan exit air toward an aft end of the fan duct. The outlet guide vane assembly is located in the fan duct downstream of the inlet fan and is configured to adjust a direction of the fan exit air received from the blades. The outlet guide vane assembly includes a first plurality of outlet guide vanes including a first outlet guide vane configured to rotate to a first angle so as to redirect the fan exit air in a first direction and a second outlet guide vane configured to rotate to a second angle so as to redirect the fan exit air in a second direction. The second outlet guide vane is located at a different circumferential position than the first outlet guide vane.

Abstract: The disclosure describes a clutch assembly that includes a first clutch element coupled to an input shaft and including a first clutch element friction surface; a second clutch element coupled to an output shaft, and a brake clutch coupled to a stationary component. The second clutch element includes a first friction surface configured to engage the first clutch element friction surface and a second friction surface opposite the first friction surface. The second clutch element is configured to move relative to the first clutch element to engage and disengage the first friction surface and the first clutch element friction surface. The brake clutch includes a brake clutch friction surface configured to engage the second friction surface of the second clutch element when the first clutch element and the second clutch element are disengaged.

Abstract: A method for shimming a thrust bearing for an accessory power take off shaft to obtain optimal meshing of bevel gears within the internal gearbox (IGB) without disassembly of the IGB is enabled by relocating the thrust bearing from the engine sump. The accessory gearbox (AGB) is driven from a power off-take from the turbine spool via the IGB. The radial position of the power take-off bevel gear is established by a radial position of the thrust bearing attached to the exterior of the casing via a housing. Candidate shims are selected from a set each having different thicknesses, the shims are formed of two halves and placed between the housing and the engine casing to adjust the radial position of the thrust bearing and consequently the power take-off bevel gear, without requiring the disassembly of the IGB.

Abstract: A printing method for selectively depositing braze powders on a surface comprises extruding a filament from a nozzle moving relative to a surface, where the filament comprises a flowable carrier mixed with a braze powder. As the nozzle moves, the filament is deposited on the surface in a predetermined pattern defined by the motion of the nozzle relative to the surface; thus, the braze powders are deposited at one or more predetermined locations on the surface.
