    摘要: A device for streaming magnetic flux data generated by an electrical generator for a power plant. The device includes a flux probe located on the generator to enable detection of a magnetic flux of the generator. The device also includes a computer having an interface, wherein the computer includes an analog-to-digital converter. In addition, the device includes a calibration circuit attached to the flux probe by a first cable and the interface by a second cable. The calibration circuit measures a resistance of the second cable and a voltage of the flux probe wherein ends of the second cable are shorted when measuring the cable resistance and the flux probe voltage. A gain is determined based on the cable resistance and flux probe voltage to provide a suitable input voltage at the interface to deliver the magnetic flux data to the computer.

    摘要: A sealing band arrangement for a gas turbine including first and second adjoining rotor disks each including a disk arm having a slot. The sealing band arrangement includes at least one first seal strip segment located within the slots, wherein the seal strip segment includes first and second ends. The sealing band arrangement also includes a tab section that extends from the first end in order to form an underlap seal with an adjacent second seal strip segment. The underlap seal enables a thickness of the first and second ends to be substantially equivalent to a thickness of the first seal strip segment in order to improve wear life of the seal strip segment. The sealing band arrangement further includes at least one wide portion formed in the first seal strip segment wherein the wide portion is wider than a remaining portion of the first seal strip segment.

    摘要: A turbine blade including a pressure sidewall (24) and a suction sidewall (26), and at least one partition rib (34) extends between the pressure and suction sidewalls (24, 26) to define a serpentine cooling path (35) having adjacent cooling channels (36a, 36b, 36c) extending in the spanwise direction (S) within the airfoil (12). A flow turning guide structure (50) extends around an end of the at least one partition rib (34) and includes a first element (52) extending from the pressure sidewall (24) to a lateral location in the cooling path between the pressure and suction sidewalls (24, 26), a second element (54) extending from the suction sidewall (26) to the lateral location in the cooling path between the pressure and suction sidewalls (24, 26). The first and second elements (52, 54) include respective distal edges (52d, 54d) that laterally overlap each other at the lateral location.

    摘要: Systems and methods for resolving fault detection in a control system is provided. The system includes an I/O module operably connected to a first, second, and third microcontroller for transmitting data. The first microcontroller is in an active state, i.e., in control, while the remaining controllers are in an idle state. The system further includes an event generator for generating an event indicative of a fault occurrence, and a means for detecting a fault event. The system also includes a means for reassigning a controller, wherein upon detection of a fault event in both the first and second controllers, the means for reassigning a controller changes the state of the third controller to active, leaving the remaining controllers idle or in a shutdown state, thereby effectively assigning control from the first controller to the third controller.

    摘要: Can-annular burners for gas turbine engines with flow conditioners having locally varying, asymmetrical patterns of circumferential perforations, to promote uniform fuel-air mixture among all premixers in the burner basket. Any one or more of the perforation pattern, pattern density, perforation profiles and perforation cross sectional area is locally varied to alter circumferential airflow into the burner basket, which in turn mitigates non-uniform thru-flow variations across the burner's air inlet plane. In some embodiments, the flow conditioner asymmetric perforation patterns are tailored for individual burner locations within the engine's combustor section annular ring, which mitigates non-uniform thru-flow variation among different respective burners in the combustor section annular ring. Thru-flow uniformity within each burner and among all the combustor section burners promotes uniform engine combustion.

    摘要: There is provided a system and a method for regenerating a material that reduce the incidence of scaling due to scale forming contaminants. The method may include reducing a temperature of a treated material exiting a wet air oxidation unit in a scale reducing heat exchanger prior to delivery of the treated material to a second heat exchanger which heats a source waste material comprising a scale forming contaminant therein with heat from the first treated material to form a heated waste material comprising the scale forming contaminant.

    摘要: A method for forming an impact weld used in an additive manufacturing process. The method includes providing a wire having a powder filler metal core located within a sheath. The wire is then inserted within a conduit having an opening. Further, the method includes providing at least one energy pulse that interacts with the sheath to pinch off at least one segment of the wire, wherein the energy pulse causes propulsion of the segment toward a substrate with sufficient velocity to form an impact weld for welding the metal core to the substrate. In particular, the energy pulse is an electromagnetic pulse, a laser energy pulse or a high electric current pulse.
