摘要： A wear sensor (30, 50, 60) installed on a surface area (24) of a component (20, 21) subject to wear from an opposing surface (74, 75). The sensor has a proximal portion (32A, 52A, 62A) and a distal portion (32C, 52C, 62C) relative to a wear starting position (26). An electrical circuit (40) measures an electrical characteristic such as resistance of the sensor, which changes with progressive reduction of the sensor from the proximal portion to the distal portion during a widening reduction wear of the surface from the starting position. The measuring circuit quantifies the electrical changes to derive a wear depth based on a known geometry of the wear depth per wear width. In this manner, wear depth may be measured with a surface mounted sensor.

摘要： In a telemetry system for use in an engine, a circuit structure (34) affixed to a moving part (20) of the engine is disposed for amplifying information sensed about a condition of the part and transmitting the sensed information to a receiver external to the engine. The circuit structure is adapted for the high temperature environment of the engine and includes a differential amplifier (102, 111) having an input for receiving a signal from a sensor (101, 110) disposed on the part. A voltage controlled oscillator (104, 115) with an input coupled to the output of the amplifier produces an oscillatory signal having a frequency representative of the sensed condition. A buffer (105, 116) with an input coupled to the output of the oscillator buffers the oscillatory signal, which is then coupled to an antenna (26) for transmitting the information to the receiver.

摘要： A thermal barrier coating (TBC) system (450) capable of self-healing has a substrate (420), a metal-based advanced bond coat (435) overlying the substrate and a ceramic top coat (440) overlying the bond coat. The bond coat (435) comprises ceramic oxide precursor materials capable of forming a non-alumina ceramic oxide composition when exposed to a thermally conditioning oxidizing environment. Embodiments of such bond coat (435) comprise rare earth elements in a range of 1-20 weight percent, and Hf in a range of about 5 to 30 weight percent or Zr in a range of about 2 to 20 weight percent. Examples of self-healing TBC systems (400, 402, 404) are provided using such bond coat (435) or its advanced bond coat chemistries in combination with conventional bond coats (433, 437) or conventional bond coat chemistries.

摘要： A gas turbine component (49) may be instrumented to provide a plurality of signals indicative of thermal measurements in a high temperature combustion environment of the gas turbine. A thermocouple arrangement may include a first thermocouple leg (50) disposed within a thickness of the component. At least two or more thermocouple legs (52, 53, 54) is each electrically connected to the first leg to form individual thermocouple junctions (56, 57, 58, 59) along the first leg for conversion of respective thermal gradients to respective electrical signals, such as electromotive force (emf) based voltages. The thermocouple arrangement may be used in combination with a thermographic system (70) to calculate heat flux over a region of the turbine component.

摘要： A telemetry system for use in a combustion turbine engine (10) that includes a first sensor (306) in connection with a turbine blade (301) or vane (22). A first telemetry transmitter circuit (312) is affixed to the turbine blade and routes electronic data signals, indicative of a condition of the blade, from the sensor to a rotating data antenna (314) that is affixed to the turbine blade or is on a same substrate as that of the circuit. A stationary data antenna (333) may be affixed to a stationary component (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna. A second sensor (335) transmits electronic data signals indicative of the stationary component to a second telemetry circuit (332), which routes the signals to the stationary antenna. The stationary antenna transmits the electronic data signals to a receiver (338).
