Abstract: A method for determining an arrival-time of a rotor blade in a turbine engine that includes the steps of: having an RF reader attached to a stationary surface in the turbine engine; having an RF tag attached to a first region of the rotor blade; having a reference RF tag attached to a rotating structure near the RF tag; in relation to a first revolution of the rotor blade occurring during the operation of the turbine engine, collecting an arrival-time for each of the RF tag and the reference RF tag with the RF reader via an RF monitoring process; comparing the arrival-time of the RF tag to the arrival-time of the reference RF tag to determine an arrival-time test result for the first region of the rotor blade for the first revolution.

Abstract: A tip shroud of a bladed rotor can be monitored for integrity using a sensor configured to detect the tip shroud. A signal from the sensor can be monitored and if the magnitude of the signal changes, such as beyond a defined amount, an indication of possible damage can be made. A baseline sensed pattern for a revolution of the tip shroud can be compared to an operation sensed pattern for a subsequent revolution, and the indication of damage can be made if there is more than the defined amount and/or percentage of difference between the patterns.
