A telemetry system for use in a combustion turbine engine () having a compressor (), a combustor and a turbine () that includes a sensor () in connection with a turbine blade () or vane (). A telemetry transmitter circuit () may be affixed to the turbine blade with an electrical connecting material () for routing electronic data signals from the sensor () 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 () affixed to the turbine blade or on a same substrate as that of the circuit. A stationary data antenna () may be affixed to a stationary component such as a stator () proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna.

Instrumented component for wireless telemetry

A telemetry system for use in a combustion turbine engine () that includes a first sensor () in connection with a turbine blade () or vane (). A first telemetry transmitter circuit () is affixed to the turbine blade and routes electronic data signals, indicative of a condition of the blade, from the sensor to a rotating data antenna () that is affixed to the turbine blade or is on a same substrate as that of the circuit. A stationary data antenna () may be affixed to a stationary component () proximate and in spaced relation to the rotating data antenna for receiving electronic data signals from the rotating data antenna. A second sensor () transmits electronic data signals indicative of the stationary component to a second telemetry circuit (), which routes the signals to the stationary antenna. The stationary antenna transmits the electronic data signals to a receiver ().
