摘要： Provided is a method for calculating a height map of a sample comprising a body of a transparent material having a refractive index with an inclined or curved surface, the body being provided on an underlying surface extending laterally from underneath the body. The method may include positioning a first area of a body of a transparent material with an inclined or curved surface and a second area of the underlying surface extending laterally from underneath the body under an optical profiler, measuring a height map of the first area and the second area with the optical profiler; and calculating a height map of the inclined or curved surface by using the refractive index, the measured height map of the first area and the second area.

摘要： A system, which is structured to evaluate a condition of a tire, includes a housing, a tire-wear detector, a tire-presence detector, and an electronic activator. The housing, when the system is deployed, is placed on a ground surface. The tire-presence detector detects a presence of a tire on the housing. The electronic activator activates the tire-wear detector when the tire-presence detector detects the presence of the tire on the housing. The tire-wear detector, when activated, detects a wear condition of the tire when the tire passes over the housing.

摘要： A method predicts an amount of wear that is expected to occur on the tubes of a steam generator as a result of vibration against another structure within the steam generator. The method includes determining a volumetric amount of material that has been worn from a location on a tube over a duration of time and employing that volume as a function of time to determine the volume of material of the tube wall that is predicted to be worn from the tube or another tube at a future time. The volumetric-based analysis enables more accurately prediction of the wear depth at a future time. This enables the plugging of only those tubes that are determined from a volumetric analysis to be in risk of breach at the future time, thus slowing the rate at which tubes of a steam generator will be plugged.

摘要： A wear monitoring system for measuring incursion depth into an abradable coating includes a layer of abradable coating including a depth. At least one measurement circuit includes a plurality of conductive leads disposed within the abradable coating. The conductive leads are spaced radially apart within a common radial plane corresponding to the depth of the abradable coating. A plurality of resistor elements corresponds with the plurality of conductive leads. Each of the plurality of resistor elements are in electrical communication with one of the plurality of conductive leads disposed within the common radial plane of the corresponding one of the plurality of conductive leads. An electrical characteristic of the circuit varies responsive to cutting of one or more of the plurality of conductive leads by a passing airfoil. A gas turbine engine and method are also disclosed.

摘要： An apparatus is provided to measure a depth of a hardened layer formed at a surface layer of a quenched workpiece. The apparatus includes an exciting coil configured to generate a magnetic flux to magnetize the workpiece and a detecting coil configured to detect the magnetic flux generated by the exciting coil. The exciting coil has a U-shaped excitation core portion and an excitation coil portion wound on the excitation core portion. The excitation core portion is arranged such that distal ends of magnetic poles of the excitation core portion face the workpiece. The detecting coil has a detection core portion and a detection coil wound on the detection core portion. The detection core portion is arranged between the magnetic poles of the excitation core portion and along a surface of the workpiece.
