Abstract
An array‐based leak location sensor has been developed and improved for application onboard spacecraft. Introduction of a diced piezoelectric element has permitted the successful utilization of lower frequency bands to perform the location. With this new device location across five integral stiffeners has been demonstrated, despite the stiffeners' strong frequency‐dependent scattering. Spatial Fourier transforms of plate wave signals determine leak location independent of the effects of dispersive multiple mode signal transport. The performance of the diced‐element array sensor on a 2×2‐m integrally stiffened aluminum plate is demonstrated.
