摘要： A system provides in-situ surface processing of an engine blade within an aircraft engine. The system includes an endoscopic processing instrument with a variable-angle tubular shaft. The processing instrument is inserted radially through a lateral access opening into the aircraft engine in a non-angled initial configuration. The lateral access opening is downstream of the engine blade. The processing instrument has a rotatably driven tool holder at a distal end of the shaft for a surface processing tool head. In an angled working configuration, a tool head inserted into the tool holder is applied to a flow edge of the engine blade. Furthermore, a process uses the corresponding system.

摘要： A method for modifying the mechanical and surface properties of a component. The method involves: removably attaching a component to at least one component support that is located within a vibratory trough of a component treatment apparatus, the at least one component support being a support shaft upon which the component is removably mountable within the vibratory trough; supplying the vibratory trough with treatment media; moving the component support or the vibratory trough so that the component is immersed into the treatment media; vibrating the vibratory trough to provide a substantially uniform surface treatment of the component, the vibratory trough being movable by at least one trough vibrating mechanism whose actuation is controlled by a controller in response to signals received from at least one sensor located on or within the vibratory trough; removing the component from the treatment media; and detaching the component from the component support.

摘要： A portable booth assembly for receiving a work piece to facilitate working on a work area of the work piece including a housing and an inner core disposed within an interior area of the housing is provided. The portable booth assembly includes an aperture that is formed in the housing and the inner core. The aperture is configured to receive the work piece. The inner core defining the aperture is configured to be supported by the work piece if the work piece is large, or support the work piece if the work piece is small, and isolate the work area within the portable booth assembly. The portable booth assembly further includes a cut out formed in the housing. The cut out is configured to enable access to the work area for working on the work area.

摘要： A method for repairing a blade tip of a turbine blade based on welding below and above a designated depth recommended for repair of turbine blades. A damaged portion of the turbine blade is inspected to identify a standard cut portion and an angled cut portion. The standard cut portion is damaged above a standard cut line and the angled cut portion is damaged below the standard cut line. The damaged portion of the turbine blade is removed. The standard cut portion is removed using a first removal process and the angled cut portion is removed using a second removal process. The angled cut portion is built up with a first weld repair process. The angled cut portion is built up to the standard cut portion. The standard cut portion and the angled cut portion are built up with a second weld repair process.
