Wireless Ultrasonic Transducer Network for Structural Health Monitoring of an Aircraft Wing
A wireless, in-situ ultrasonic guided wave structural health monitoring (SHM) system has been developed and tested for aircraft wing inspection. It applies small, low cost and light weight piezoelectric (PZT) disc transducer network to the structural surface, and embeds a miniaturized diagnostic device for data collection and analysis. The whole system can be powered by an energy harvesting device such as an X-band microwave rectenna that converts illuminating microwave energy into DC. The collected data and processed results can be sent out wirelessly with a Zigbee radio. It showed good potential for crack and corrosion monitoring on complex panel structures such as an aircraft wing.
