NON-DESTRUCTIVE STRINGER INSPECTION APPARATUS AND METHOD

A hat stringer inspection device permits continuous inspection of hat stringers as one or more probes are moved along the length of the hat stringer. Probes may be magnetically coupled to opposing surfaces of the structure, including, for example, where one of the probes is positioned inside the hat...

Beschreibung
Zusammenfassung:	A hat stringer inspection device permits continuous inspection of hat stringers as one or more probes are moved along the length of the hat stringer. Probes may be magnetically coupled to opposing surfaces of the structure, including, for example, where one of the probes is positioned inside the hat stringer and the probes are magnetically coupled across the surface of the hat stringer. The device may be autonomous with a feedback-controlled motor to drive the inspection device along the hat stringer. Magnetic coupling is also used to re-orient the position and/or alignment of the probes with respect to changes in the hat stringer or shapes, sizes, and configurations of hat stingers.
