Patent number: 9395339Abstract: A multi-sensor NDI probe having means for self-alignment of the NDI sensors in conjunction with the movement of the sensor suite along the length of a hollow elongated stiffener having a rounded cap. The apparatus comprises a large-radius curved ultrasonic transducer array with cylindrical focus, which provides complete coverage for the rounded cap, two small-radius convex curved transducer arrays for NDI of the lower outside radii, and two linear transducer arrays for NDI of the sides of the stiffener. The five transducer arrays are supported by respective compliant assemblies which facilitate proper adjustment of the location (i.e., position and orientation) of the transducer arrays during scanning. The positions of the transducer arrays are adjusted to account for geometric variations in the stiffener.Type: GrantFiled: August 26, 2013Date of Patent: July 19, 2016Assignee: The Boeing ComapanyInventors: Dennis P.

Patent number: 7263889Abstract: 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.Type: GrantFiled: March 21, 2007Date of Patent: September 4, 2007Assignee: The Boeing CompanyInventors: James C.
