    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. Time-of-flight data points are collected via an RF monitoring process that includes: emitting an RF signal from the RF reader and recording a first time; 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 and recording a second time; and determining the time-of-flight data point as being the duration occurring between the first time and the second time. The RF monitoring process is repeated until multiple time-of-flight data points are collected. A minimum time-of-flight is determined from the multiple time-of-flight data points, and the arrival-time for the rotor blade is determined as being a time that corresponds to the minimum time-of-flight.

    Abstract: A damping system for a turbomachine slip ring includes a slip ring assembly. The slip ring assembly includes a rotating component which is coupled at one end to a rotor shaft of the turbomachine and a stator component which circumferentially surrounds a rotatable center core portion of the rotating component. The system further includes a static structure which defines a carrier sleeve where the carrier sleeve circumferentially surrounds a portion of the stator component. The system also includes a damping material which extends radially between an inner surface of the carrier sleeve and an outer surface of the stator component so as to dissipate vibrational energy of the slip ring assembly during rotation of the rotor shaft.

    Abstract: A system for transmitting data from a rotating component of a turbomachine includes a plurality of thermal sensors coupled to corresponding rotatable components within the turbomachine where each thermal sensor generates a discrete analog signal indicative of temperature. A plurality of transmitter assemblies is coupled to an end of a rotor shaft of the turbomachine. The plurality of transmitter assemblies comprises a first transmitter assembly and a second transmitter assembly. The first transmitter assembly is configured to receive the discrete analog signals from the plurality of thermal sensors, multiplex the plurality of discrete analog signals into a single amplifier and an analog-to-digital converter to generate a single stream of digital data therefrom. The system also includes a slip ring assembly having a plurality of conductive rings where at least one of the conductive rings defines a digital signal path between the first transmitter assembly and a data acquisition system.
