Curlin Air

Contactless Air-Coupled Ultrasonic Flaw Detector

The portable Curlin Air utilizes air-coupled ultrasonics and requires no surface preparation and no direct contact with test object. It performs sensitive inspections to detect voids, impact damage, and disbonds in a wide variety of water-incompatible materials. Originally used primarily for aerospace composites, the Curlin Air is referenced specifically by major aerospace manufacturers in their published inspection procedures. It has since evolved to evaluate a diverse range of materials including propellants and wood and foam panels.

Air-coupled ultrasonic techniques are used when testing sensitive materials which are at risk of contamination during the testing processes or in situations when the cost of removing special coatings from the material to be tested is impractical. Wetting agents or powders typically used in conventional ultrasonic testing can lead to degradation of sensitive components.
