Integrated phased array transducer, system and methodology for structural health monitoring of aerospace structures
Abstract:
The invention provides an integrated Phased Array (PhA) structural radar transducer, permanently bonded to a structure, that can provide reliable electromechanical connection with corresponding miniaturized electronic SHM device installed above it. The integrated PhA transducer consists of a set of aligned piezo-electric discs with wrap around electrodes for transceiving of elastic ultrasonic waves, plurality of electrical traces and contact pads, several layers of a flexible printed circuit board, electromagnetic shielding between channels and overall, one electromechanical multi-pinned connector and all that integrated into one small unit easy for surface installation by bonding and final application on real structures. The integrated PhA transducer, as a key component of SHM (Phased Array Monitoring for Enhanced Life Assessment) system, has two principal tasks to reliably transceive elastic waves and serve as a reliable sole carrier or support for associated sophisticated SHM electronic device attached above.
