<p>A system for inspecting the joint of a composite structure includes a transmitting transceiver and a receiving transceiver, as well as a processing element Typically, the composite structure includes first and second panels that are connected to define the joint, with the second panel extending outwardly from the first panel of the joint. Moreover, the composite structure includes a filler disposed at the joint. The transmitting transducer is disposed proximate an input side of the second panel and can transmit an ultrasonic signal into the second panel such that at least a portion of the signal reflects off of the first panel at the joint and exits an output side of the second panel. A receiving transducer disposed proximate the output side of the second panel can receive a reflected portion of the ultrasonic signal. And a processing element is capable of identifying a defect in the composite structure. <IMAGE></p> |
