Abstract:

The capability of embedded piezoelectric wafer active sensors PWAS to perform in-situ nondestructive evaluation NDE is explored. Laboratory tests are used to prove that PWAS can satisfactorily perform Lamb wave transmission and reception. Subsequently, crack detection in an aircraft panel with the pulse echo method is illustrated. For large area scanning, a PWAS phased array is used to create the embedded ultrasonics structural radar EUSR. Opportunities for implementation into Air Force vehicles and the research needs are also discussed.
