WIRELESS ANTENNA SYSTEM FOR SENSORS ON CIRCUMFERENTIAL INTERIOR SURFACE OF TURBOMACHINE CASING

Abstract:

A wireless sensor antenna system for a turbomachine including a rotating blade including a passive sensor is disclosed. The wireless sensor antenna system includes an antenna extending continuously along a circumferential interior surface of a casing of the turbomachine that surrounds the rotating blade. The antenna is configured to receive a return wireless signal from the passive sensor. A power transmission element extends along the at least portion of the circumferential interior surface of the casing to power the passive sensor by emitting an electromagnetic signal to power the passive sensor.
