  • Patent number: 8527241
    Abstract: A telemetry system for use in a combustion turbine engine (10) having a compressor (12), a combustor and a turbine (16) and includes a sensor (118) in connection with a turbine blade (111) or vane (23). A transmitter assembly (117) includes a telemetry transmitter circuit/transceiver may be affixed on a turbine blade (111) or seal plate (115) proximate the turbine blade with a first connecting material (119) deposited on the turbine blade (111) for routing electronic data signals, indicative of a condition of the turbine blade (111), from the sensor (118) to the telemetry transmitter circuit/transceiver. An induction power system for powering the telemetry transmitter circuit/transceiver may include a rotating data antenna (116) affixed to the seal plate (115) with an electrical connection (122) between the telemetry transmitting circuit/transceiver for routing electronic data signals from the telemetry transmitter circuit/transceiver to the rotating data antenna (119).
    Type: Grant
    Filed: February 1, 2011
    Date of Patent: September 3, 2013
    Assignee: Siemens Energy, Inc.
    Inventors: David J. Mitchell, Ramesh Subramanian, Cora Schillig, Anand A. Kulkarni, Vinay Jonnalagadda, Bulent Acar, Sankar Nellian, James P. Williams, Edward R. Roesch

  • Patent number: 8192166
    Abstract: A turbine blade is provided comprising: an airfoil including upper and lower ends; a root coupled to the airfoil lower end; a shroud coupled to the airfoil upper end; and at least one sealing rail extending radially outwardly from an upper surface of the shroud and extending generally along a circumferential length of the shroud. The sealing rail may comprise a mid-section, opposing end sections and at least one intermediate section located between the mid-section and one of the opposing end sections. An axial thickness of the rail may vary.
