    摘要: An imaging system for on-line imaging of a component in a gas turbine engine. The imaging system includes a flexible imaging bundle formed by a plurality of optical elements. An imaging end of the optical elements images a component in a hot gas path of the engine during operation of the engine and a viewing end provides an image of the component at a location displaced from the hot gas path. The optical elements are surrounded by a flexible metal sheath that is permeable to air to provide cooling air the optical elements from an air source surrounding the flexible imaging bundle.

    摘要: A method for non-destructive evaluation of an article of manufacture (30) by coating the article with a temperature-sensitive coating (34), stimulating the article with energy (18) to induce temperature changes in the article responsive to features of the article, then evaluating (24) a resulting topography of energy-induced changes (50, 52, 53) in the coating (34). The energy imparted to the article may be, for example, electromagnetic, magnetic, or sonic energy that produces localized changes in temperature in the article (30) in response to features (32) of the article such as flaws or other discontinuities. The coating (34) may be a suspension of liquid crystals in a liquid, and the energy may be an application of sonic energy. The coating may be a material that hardens (42, 54) or softens (44, 56) upon a slight increase in temperature. Layers (34, 35) of different energy-sensitive coatings (38, 40) may be applied to indicate different aspects of features of the article.

    摘要: A joint having bond line grains that nucleate in the joint region and grow into the adjoined solid substrates. The resulting bond line grains have a size that is greater than a thickness of a molten region. The surfaces of the substrates are cold worked to a desired degree of residual stress prior to the bonding process so that the recrystallization of the substrate surface necessary for the grains to grow into the substrates results in a reduction in the local free energy.

    摘要: The present invention provides an eddy current sensing device capable of in-situ operation within a high temperature and high vibration environment of a combustion turbine engine. The eddy current sensing device is preferably utilized in an eddy current sensing system for monitoring crack formation and displacement of rotating members of the combustion turbine engine. The method according to the present invention provides inducing eddy currents in the rotating member, detecting the eddy currents, providing a signal indicative of the detected eddy currents, filtering the signal based on the condition to be monitored and evaluating the filtered signal to determine whether the condition, such as the formation of a crack in the surface of the rotating member exists, and if so, determining whether the condition is critical or routine.

    摘要: Apparatus and method for temperature mapping a rotating component (12) in a high temperature combustion environment. The apparatus includes a thermal imager (14) having a field of view to sense infrared (IR) emissions. Emissivity of a surface of the component is subject to variation in the combustion environment. A radiance emitter (18) defines a spot within the field of view of the thermal imager. The spot indicates a respective emissivity value. A processor (30) is connected to the thermal imager to generate a radiance map of the component based on the IR emissions from the component. The processor includes a thermal calibration module configured to calibrate the radiance map based on the emissivity value of the spot within the field of view of the thermal imager to generate a calibrated thermal map of the component that displays absolute temperature over the surface of the component.

    摘要: A hand-held thermography system (8). A generator (10) supplies current to a transformer (15) in a handle (16). An induction coil (20) connected to the transformer (15) extends from the handle (16). The induction coil (20) induces eddy currents in a test object (50), producing a thermal topography on a surface (52) of the object (50) that reveals structural features including defects in the object. An infrared camera (24) mounted on the transformer (16) digitizes images of the thermal topography. A controller (12) processes the images, displays them on a monitor (14), and stores them in a digital memory (11) for evaluation. Digitized positional data relating the position of the image to the surface may also be stored. An operator (40) presses a trigger (17), signaling the controller (12) to start current to the induction coil (20) and simultaneously to acquire and process one or more images from the camera (24). The images may be evaluated visually and/or by computerized analysis techniques for analyzing defects in the object.
