Description

ABSTRACT:
An ultrasonic inspection system for determining the presence, location, and size of flaws in laminated structure such as an "I" stiffener in a single inspection cycle. The exemplary system includes an immersion tank, five (5) single probes, 188 transducers, four (4) motor assemblies, two (2) encoder assemblies, a collection tank, and a recirculation assembly. The probes are designed to match the shape of the stringer. Two (2) motors fore and two (2) motors aft of the immersion tank, produce information related to the position of the stringer with respect to the position of the transducer. The position encoder is spring-loaded against the stringer.
