Description

The “Dripless Bubbler” technique[1–3] merges the spatial resolution and coupling advantages of focused-beam ultrasonic immersion probes with an apparatus for maintaining a contained water pool and a commercially available portable robotic scanner and image processing software. The focused probe resolution is necessary for the detection and characterization of corrosion on the inside of the fuselage skin, within laps and joints and disbonds or other defects in composite materials. The system scans over the aircraft skin, following the curvature of a fuselage while maintaining a transducer orientation normal to the surface. Surface irregularities including button-head rivets and lap splices are scanned over with no couplant loss.
