1. A method of monitoring a rotor blade of a turbine engine that includes a plurality of blades mounted to a rotor shaft, comprising:
- a) securing a RFID tag that includes an antenna to at least one of the rotor blades;
b) securing a RFID reader on a stationary surface on the turbine engine in operational proximity to the RFID tag; and
c) during operation of the turbine engine, monitoring the RFID tag with the RFID reader;
wherein the RFID tag is positioned and secured to the rotor blade such that the formation and/or propagation of cracks that are expected to form in the area of the rotor blade on which the RFID tag is positioned and secured disable the RFID tag such that the RFID tag is not readable to the RFID reader.

10. A turbine engine comprising:
-
a plurality of rotor blades mounted to a shaft; a RFID tag that includes an antenna secured to at least a plurality of the rotor blades; a RFID reader secured to a stationary surface on the turbine engine in operational proximity to the RFID tag; wherein the RFID reader is configured to monitor the RFID tags as the RFID tags pass the RFID reader during operation; wherein the RFID tag is positioned and secured to the rotor blade such that the formation and/or propagation of cracks that are expected to form in the area of the rotor blade on which the RFID tag is positioned and secured disable the RFID tag. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
