摘要： An apparatus and method for radiation measurement are used to determine clearance of a rotating gas turbine component. The apparatus includes a probe body on a stationary component outward of the rotating component and a pair of sensor assemblies coupled to the probe body. Each sensor assembly includes a plurality of prisms coupled to the probe body Each prism of the plurality of prisms has a distinct angular orientation to direct radiation from the focusing lens to the rotating component surface off-axis with respect to an axis of the respective radiation source of the pair of radiation sources and with less directional variation than radiation from the respective radiation source.

摘要： A system is provided with a measurement system having a light source, a light sensor, and a controller coupled to the light source and the light sensor. The controller is configured to determine a clearance between a rotor and a casing at least partially based on an interruption of light transmitted from the light source to the light sensor.

摘要： A milling device for machining a slot into an inner surface of a casing for a gas turbine engine. The milling device includes a frame assembly including multiple structural guides configured to engage structural features on the inner surface of the casing to maintain an axial position of the milling device relative to a longitudinal axis of the casing. The milling device also includes a milling cutter coupled to the frame assembly. The milling device is configured to be displaced in a circumferential direction relative to the longitudinal axis to machine the slot, via the milling cutter, along the inner surface of the casing in the circumferential direction.

摘要： A method for determining an arrival-time of a rotor blade that includes attaching an RF reader to a stationary surface and an RF tag to the rotor blade. Strength-of-signal data points are collected via an RF monitoring process that includes: emitting an RF signal from the RF reader; receiving the RF signal at the RF tag and emitting a return RF signal by the RF tag in response thereto; receiving the return RF signal at the RF reader; measuring a signal strength of the return RF signal as received by the RF reader; and determining the strength-of-signal data point as being equal to the measured signal strength. The RF monitoring process is repeated until multiple strength-of-signal data points are collected. A maximum strength-of-signal is determined from the multiple strength-of-signal data points, and the arrival-time for the rotor blade is determined as being a time that corresponds to the maximum strength-of-signal.

摘要： A system includes a thermographic temperature sensor that may measure a temperature of a fluid. The thermographic temperature sensor includes a probe, an optical source coupled to the probe, and a detector coupled to the probe. The system also includes a housing of the probe; and a light pipe of the probe disposed within the housing and including a thermographic phosphor that may phosphoresce in response to absorbing light from the optical source. The phosphorescence by the thermographic phosphor is representative of a temperature of the fluid within a flow path of the fluid, and the detector may detect the phosphorescence by the thermographic phosphor.

摘要： An optical sensor for a rotating blade stage of a turbomachine is disclosed. The optical sensor includes a housing to be mounted relative to a circumferential interior surface of a casing of the turbomachine. Optical fiber(s) are operatively coupled to the housing for communicating: an optical signal for sending toward the rotating blade stage and a return optical signal reflected by the rotating blade stage, through the casing. An optical signal redirecting element is configured to redirect the optical signal from optical fiber(s) inwardly toward the rotating blade stage relative to the casing, and redirect the return optical signal reflected by the rotating blade stage into the at least one optical fiber. Optical fiber(s) have a longitudinal shape configured to follow the circumferential interior surface of the casing.
