摘要： A generator stator core (10) that includes a plurality of through-bolts (20) extending through the stator core. Each through-bolt includes a threaded end on which is positioned a conical washer (32) and a through-bolt nut (30), where the through-bolt nuts are tightened against the washers to compress laminate plates (14) and hold the stator core together. The stator core further includes a through-bolt tension monitoring system including a fiber Bragg grating sensor (36) mounted to one or more of the conical washers and being provided in at least one optical fiber. The monitoring system further includes a monitoring device providing an optical signal to each of the fiber Bragg grating sensors and receiving a reflected signal from the fiber Bragg grating sensors where the reflected signal provides an indication of strain on the washer to provide an indication of how tight the nut is on the through-bolt.

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 metal cladding process utilizing a feed material (66) formed as a hollow sheath (68) containing a powdered core (70) including powdered metal and powdered flux material. The powdered metal and flux may have overlapping mesh size ranges. The sheath may be an extrudable subset of elements of a desired superalloy cladding material, with the powdered metal and powdered flux materials complementing the sheath to form the desired superalloy material when melted. The powdered metal may include an excess of titanium to compensate for a reaction of titanium with oxygen or carbon dioxide in a shielding gas. Heat for melting may be provided by an energy beam (64) or by utilizing the feed material as an electrode in a cold metal arc welding torch (54).

摘要： A method for repairing a damaged portion (144) of a brazed-on gas turbine engine seal (142) without the need to remove and to replace the entire seal. The damaged portion is removed to reveal a repair surface (146) of the underlying superalloy material, and a new seal structure (148) is formed by an additive manufacturing processes using a laser beam (124) to melt a powder (116) including superalloy material (116') and flux material (116''). The flux material forms a protective layer of slag (132) over the melted superalloy material, thereby permitting the new seal structure to be formed directly onto the underlying superalloy material without the need for an intervening braze layer.

摘要： A process for growing a substrate (24) as a melt pool (28) solidifies beneath a molten slag layer (30). An energy beam (36) is used to melt a powder (32) or a hollow feed wire (42) with a powdered alloy core (44) under the slag layer. The slag layer is at least partially transparent (37) to the energy beam, and it may be partially optically absorbent or translucent to the energy beam to absorb enough energy to remain molten. As with a conventional ESW process, the slag layer insulates the molten material and shields it from reaction with air. A composition of the powder may be changed across a solidification axis (A) of the resulting component (60) to provide a functionally graded directionally solidified product.

摘要： Laser cladding filler material is introduced in a pattern on a on a substrate (200) by a filler distribution apparatus (300) having a linear or polygonal array of dispensing apertures (331-336) for uniform distribution in advance of or during a laser beam (180) transferring optical energy to the substrate (200).

A mechanical feed mechanism, such as an auger (340), is adapted for feeding filler material (F) from the internal chamber (320) through the distribution apertures (331-336). A feed mechanism drive system (135) is coupled to the mechanical feed mechanism (340), adapted for selectively varying filler material feed rate. The distribution aperture array (331-336) may be selectively reconfigured to vary selectively the filler material distribution pattern.

摘要： A gas turbine combustor vibration sensing system includes a non contact reflective optical vibration sensor adapted for reflecting photons off of a component within the combustor with a photon source and receiving reflected photons with a photon detector. Exemplary combustor internal components include the combustor basket or transition. A vibration analyzer is coupled to the vibration sensor, for correlating photons received by the detector with vibration characteristics of the component. Vibration characteristics in turn can be correlated with combustion characteristics, including by way of example flame front position and flameout conditions. Vibration characteristic information may be used as an operational parameter by a turbine monitoring system to modify operation of a gas turbine.
