Abstract

A telemetry system for use in a combustion turbine engine (10) having a compressor (12), a combustor and a turbine (16) that includes a sensor (306) in connection with a turbine blade (301) or vane (22). A telemetry transmitter circuit (312) may be affixed to the turbine blade with an electrical connecting material (307) for routing electronic data signals from the sensor (306) to the telemetry transmitter circuit, the electronic data signals indicative of a condition of the turbine blade. A resonant energy transfer system for powering the telemetry transmitter circuit may include a rotating data antenna (314) affixed to the turbine blade or on a same substrate as that of the circuit. A stationary data antenna (320) may be affixed to a stationary component such as a stator (323) proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna.
