摘要： Superalloy components are joined by mating a recess formed in one component with a corresponding projection formed in another component along a contact surface. The components are compressed along the contact surface and resistance heat welded to each other. Current is passed between the components at a selected flow rate and application time until localized melting occurs along the contact surface, and they are mutually affixed to each other. When repairing a damaged surface portion of a superalloy material component, the damaged portion is removed to form an excavated recess. A repair splice is formed, preferably of a same material with similar mechanical structural properties, having a mating projection with profile conforming to the corresponding recess profile. The splice and substrate are resistance heat welded under compression pressure until localized melting occurs along the contact surface, so that they are mutually affixed.

摘要： Superalloy components, such as service-degraded turbine blades and vanes, are clad by laser beam welding. The welding/cladding path, including cladding application profile, is determined by prior, preferably real time, non-contact 3D dimensional scanning of the component and comparison of the acquired dimensional scan data with specification dimensional data for the component. A welding path for cladding the scanned component to conform its dimensions to the specification dimensional data is determined. The laser welding apparatus, preferably in cooperation with a cladding filler material distribution apparatus, executes the welding path to apply the desired cladding profile. In some embodiments a post-weld non-contact 3D dimensional scan of the welded component is performed and the post-weld scan dimensional data are compared with the specification dimensional data. Preferably the welding path and/or cladding profile application are modified in a feedback loop with the pre- and/or post-welding 3D dimensional scanning.

摘要： An intercoupled stator core is separated from a non-vertically oriented (including horizontal) generator frame by decoupling the stator core and frame coupling members and interposing a slidable member between them. Thereafter they are separated relative to each other on the sliding member. The sliding or slidable member may comprise a rail, or alternatively a roller adapted for rolling contact with one of the opposed stator core or generator structures and an engagement surface in contact with the other structure. A system for separating the stator core from a non-vertically oriented generator frame includes first and second raising end plates adapted coupled to axial ends of the stator core. The end plates project outwardly from the generator frame ends, for coupling to a raise mechanism. After the raise mechanism raises the stator core the slidable member is interposed between the stator core and generator frame.

摘要： A seal assembly (50, 60) for a gas turbine engine for controlling air flow between a diffuser (48) and rotor disks comprising first and second annular flange ends (52, 54) and an annular seal mid-section (56) between and operatively connected to the flange ends (52, 54). The first and second annular flange ends (52, 54) abut respective outer frame members (46) of the diffuser, whereby a fluid flow path is formed between the seal assembly (50, 60) and the rotor disks (42). The first and second end flanges (52, 54) are composed of a material having a coefficient of thermal expansion that is substantially the same as a coefficient of thermal expansion of the material of the outer frame members (46). In addition, the material of the seal mid-section (56) has a coefficient of thermal expansion that is different than that of the materials of the annular flange ends (52, 54) and outer frame members (46).

摘要： Operational gas turbine engine housing or casing dynamic strain, temporary or permanent displacement and/or temperature is measured by a distributed fiber optic sensing system (DFOSS) utilizing optical frequency domain reflectometry (OFDR) that is coupled to the turbine engine housing. The DFOSS/OFDR system measures localized variances in strain along the length of an optical fiber (OF), which are correlated with turbine engine housing displacement. Temperature influence on the measured localized strain variances is accounted for by obtaining temperature information from an another measurement system or by taking the same type OFDR measurements on unrestrained optical fiber (OF) and deriving compensated strain measurements that are not temperature influenced. The derived strain measurements along the DFOSS are correlated with housing displacement. Other embodiments include separate displacement measuring modules, each including DFOSS optical fibers, coupled along the engine housing.

摘要： A gas turbine shaft bearing system (bearing and/or seal component) service method and service tool that applies biasing force between a gas turbine shaft and a bearing system component supporting the shaft, so that the bearing system component can be removed or installed. The bearing system service tool is coupled directly to the bearing system component and the shaft, preferably without the need for external fixtures. A biasing force generator, such as a hydraulic unit applies a force on the bearing system component to cause component movement on or off the shaft. Counter-biasing forces are resisted by the fixed position turbine shaft. By exerting biasing force directly between the turbine shaft and bearing system component the service tool can be constructed of smaller, man portable components that are more easily maneuvered within relatively confined turbine service spaces, which are common in field installations.
