摘要： An electrical assembly for use in various operating environments such as a casing of a combustion turbine 10 is provided. The assembly may include an electrical energy-harvesting device 51 disposed in a component within the casing of the turbine to convert a form of energy present within the casing to electrical energy. The harvesting device is configured to generate sufficient electrical power for powering one or more electrical devices therein without assistance from an external power source. One example of electrical devices wholly powered by the energy harvesting device may be a sensor 50 connected for sensing a condition of the component within the casing during operation of the combustion turbine. Another example of electrical devices wholly powered by the energy harvesting device may be a transmitter in communication with the sensor for wirelessly transmitting the data signal outside the casing.

摘要： Methods for laser additive manufacture are disclosed in which a plurality of powder layers (48, 50 and 52) are delivered onto a working surface (54A) to form a multi-powder deposit containing at least two adjacent powders layers in contact, and then applying a first laser energy (74) to a first powder layer (48) and a second laser energy (76) to a second powder layer (52) to form a section plane of a multi-material component. The multi-powder deposit may include a flux composition that provides at least one protective feature. The shapes, intensities and trajectories of the first and second laser energies may be independently controlled such that their widths are less than or equal to widths of the first and second powder layers, their intensities are tailored to the compositions of the powder layers, and their scan paths define the final shape of the multi-material component.

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.
