Abstract: A slip ring assembly includes a pair of conductive rings consecutively positioned along a center shaft of the slip ring assembly. The pair of conductive rings are electronically coupled to a high frequency signal source via a first twisted wire pair. The pair of conductive rings are electronically coupled to a data processor via a second twisted wire pair. The first and second twisted wire pairs have constant target impedances that are substantially similar. The first and second conductive rings are axially spaced at an axial distance that is sized so as to maintain the constant target impedance across the first and second conductive rings during transmission of a high frequency signal from the high frequency signal source to the data processor. The slip ring assembly provides a method for impedance matching across the conductive rings of the slip ring assembly.

Abstract: 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.

Abstract: 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.
