Wireless Ultrasonic Transducer Network for Structural Health Monitoring of an Aircraft Wing
نویسندگان
چکیده
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.

The concept of in situ Structural Health Monitoring (iSHM) involves incorporating a diagnostic capability to detect and monitor damage in structural ‘hot spots’. These systems allow the introduction of Condition Based Monitoring (CBM) approaches for ageing aircraft fleets and thus could help significantly reduce through-life support costs and increase aircraft availability.

متن کاملSimultaneous Ultrasonic Monitoring of Crack Growth and Dynamic Loads during a Full Scale Fatigue Test of an Aircraft Wing
An in situ ultrasonic angle beam method has been developed to detect and size fatigue cracks emanating from fastener holes. The method employs transducers mounted in a pitch-catch configuration on each side of the hole, and the modulation of received signals with load is used to detect and size small fatigue cracks. The focus of this paper is the monitoring of a series of critical fastener hole...
