Abstract: A rotary component may comprise a first structure configured to rotate about an axis and a second structure configured to rotate about the axis. A support structure may be coupled to the first structure at a first attachment location and to the second structure at a second attachment location. The support structure may be configured to separate from the first structure and the second structure in response to a centrifugal force generated by the first structure and the second structure rotating about the axis.

Abstract: A method for abrasive flow machining includes moving an abrasive media through a high-aspect passage of a workpiece. Local pressure of the abrasive media is increased at target abrasion surfaces of the high-aspect passage using a passage geometry that is configured to direct flow of the abrasive media into the target abrasion surfaces such that the target abrasion surfaces are preferentially polished by the abrasive media over other, non-targeted surfaces of the high-aspect passage at which the flow of the abrasive media is not directed into.

Abstract: An embodiment of an apparatus includes a centrifugal drive unit, an arm assembly, an optional dynamic balancing ring, and a workpiece fixture. The arm assembly is operatively connected to the centrifugal drive unit and configured to revolve about a primary axis perpendicular to the arm. The workpiece fixture is mounted to the arm assembly, and is configured to rotate at least one workpiece about at least one secondary axis outboard of the primary axis.
