Abstract: A wireless power-transfer system as may be used in a telemetry system in a high-temperature environment of a combustion turbine engine is provided. A power-transmitting coil assembly (110) may be affixed to a stationary component (112) of the turbine engine proximate to a rotatable component (104) of the turbine engine. The power-transmitting coil assembly may include a plurality of annularly arranged wire-guiding segments (130) affixed to the stationary component of the turbine engine. Each wire-guiding segment may include a pair of parallel grooves (132) spaced apart from one another. A wire (140) is disposed in the pair of parallel grooves to form in a singular layer a power-transmitting coil (136) in response to an alternating current power signal supplied to the power-transmitting coil assembly to energize the wire.

Abstract: Wireless telemetry system (100) that makes use of integrated wide-bandgap semiconductor technology in a high-temperature environment of a gas turbine engine is disclosed. A wide-bandgap integrated circuitry (WBIC) (98) includes a telemetry transmitter circuitry (106) connected to receive a sensor signal indicative of a condition of the turbine blade. The WBIC may further include power-conditioning circuitry (150) to condition power in a power transfer system (108). A non-stationary antenna (142) may be affixed to the turbine blade. The telemetry transmitter circuitry is connected to the non-stationary antenna to transmit a telemetry signal indicative of the condition of the turbine blade, and a stationary antenna (144) may be affixed to a stationary component to receive the telemetry signal indicative of the condition of the turbine blade. The WBIC is effective for reduction in the footprint and component count compared to telemetry systems involving a discrete circuit implementation.
