Abstract
A system for wirelessly monitoring temperatures of a gas turbine engine comprising a wireless sensor positioned on or in a component of the engine, one or more interrogating antennas capable of transmitting an RF signal to the wireless sensor and receiving an RF return signal from the wireless sensor, and a processing unit capable of interpreting the RF return signal to determine a temperature of the component inside the engine. In an embodiment, the wireless sensor comprises polymer derived ceramics ('PDC') deposited on an Inconel surface of the engine. In an embodiment, the wireless sensor sustains temperatures up to 1000° C. during long term operation of the part of the engine. In an embodiment, the wireless sensor comprises multiple layers including a metallic patch antenna, a PDC layer, and a bond coat which provides a metallic ground plane for the sensor.
