Abstract: A self-aligning probe assembly has one or more ultrasonic transducers adapted to transmit an ultrasonic shear wave into the inside surface of the hollow structure such as an aircraft fuse pin and to receive the shear wave emerging from the inside surface of the hollow structure. The nature of the received shear wave indicates the presence of flaws or damage in the inspected part. The probe assembly can be used to inspect fuse pins on aircraft without having to remove the aircraft engines.

Abstract: 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.

Abstract: There is provided an ultrasonic inspection device that provides a locking mechanism for inspecting components at preset angles. The inspection device can inspect a component along an arc by inspecting the component at each preset angle, which provides complete and repeatable inspection results. The inspection device comprises a housing with a channel for the passage of an ultrasonic signal and an ultrasonic transducer to transmit and receive the ultrasonic signals. The housing also includes a rotating reflector to reflect the ultrasonic signal. Using a handle on the housing rotatably attached to the rotating reflector, a technician can rotatably position and lock the rotating reflector at a preset angle. The rotating reflector can be rotatably locked by a spring-loaded ball that is selectively received in detents defined by the rotating reflector or handle.
