Abstract: Additive-based electroforming manufacturing methods for producing turbomachine components and other metallic articles are provided, as are metallic articles manufactured utilizing such manufacturing methods. In various embodiments, the method includes providing a sacrificial tooling structure having a component-defining surface region. A metallic body layer or shell is deposited over the component-defining surface region utilizing an electroforming process. The tooling structure is removed, while the metallic body layer is left substantially intact. After tooling structure removal, the metallic body layer is further processed to complete fabrication of the metallic component.

Abstract: An electromagnetic machine includes a spherical stator, an armature, a first coil, and a second coil. The spherical stator has an outer surface, and the outer surface has a plurality of spaced-apart protuberances formed thereon. Each protuberance extends radially from, and is disposed normal to, the outer surface. The armature is disposed adjacent to the spherical stator and includes a magnet that emanates a magnetic field. The magnet has at least one of its magnetic poles facing the spherical stator. The first coil is wound around at least a portion of the spherical stator, and is disposed between the plurality of spaced-apart protuberances and along latitudinal lines of the spherical stator. The second coil is wound around at least a portion of the spherical stator, and is disposed between the plurality of spaced-apart protuberances and along longitudinal lines of the spherical stator.

Abstract: Additive-based electroforming manufacturing methods for producing turbomachine components and other metallic articles are provided, as are metallic articles manufactured utilizing such manufacturing methods. In various embodiments, the method includes the step or process of additively manufacturing a sacrificial tooling structure having a component-defining surface region. A metallic body layer or shell is deposited over the component-defining surface region utilizing an electroforming process such that a geometry of the component-defining surface region is transferred to the body layer. The tooling structure is chemically dissolved, thermally decomposed, or otherwise removed, while the metallic body layer is left substantially intact. After tooling structure removal, the metallic body layer is further processed to complete fabrication of the metallic component. In certain implementations, the method may further include the step or process of depositing an electrically-conductive base coat over the component-defining surface region of the tooling structure for usage in the subsequently-performed electroforming process.

Abstract: A multi-axis gimbal assembly includes a spherical armature, a first coil, a second coil, a third coil, a bracket, a stator, and a motor. The spherical armature has first, second, and third perpendicularly disposed axes of symmetry. The first coil is wound about the first axis of symmetry, the second coil is wound about the second axis of symmetry, and the third coil is wound about the third axis of symmetry. The bracket is rotationally coupled to the spherical armature to allow relative rotation between the spherical armature and bracket around only the first axis of symmetry. The stator is rotationally coupled to the bracket to allow relative rotation between the stator and bracket around only the second axis of symmetry. The motor is coupled to the stator and is configured to simultaneously rotate the stator, the bracket, and the spherical armature around the third axis of symmetry.
