Publication number: 20100139404Abstract: An ultrasonic inspection apparatus may include a chamber partly filled with water from a first portion of the chamber to a water-line disposed apart from a second portion of the chamber, and at least one transducer disposed apart from the water-line. The at least one transducer may emit ultrasonic signals through a portion of a part being inspected towards the water-line. The water-line may reflect the ultrasonic signals emitted from the at least one transducer off the water-line, back through a portion of a part being inspected, and back to the at least one transducer. In such manner, one or more portions of a complex-shaped part may be inspected.Type: ApplicationFiled: December 8, 2008Publication date: June 10, 2010Inventors: William J. Tapia, Gary E.

Patent number: 7703327Abstract: An apparatus and method for inspecting a structure are provided which include receiving probes and area transducers disposed proximate opposite surfaces of a structure under inspection. An area transducer uniformly emits ultrasonic signals over an area which may be scanned by a receiving probe without corresponding movement of the area transducer. An area transducer may be moved over the surface of the structure or repositioned to provide additional inspection area for the receiving probe to scan, including to provide for continuous inspection. Multiple area transducers may be used in sequence to provide for continuous inspection. Multiple receiving probes may be used, independently or collectively as an array, to increase inspection of a structure, taking advantage of the large area of ultrasonic signals emitted by one or more area transducers.Type: GrantFiled: September 16, 2004Date of Patent: April 27, 2010Assignee: The Boeing CompanyInventors: Gary E. Georgeson, Michael D. Fogarty, Richard Bossi

Patent number: 7706985Abstract: In a non-limiting, exemplary system for in-situ monitoring of a composite workpiece, at least one ultrasonic testing transducer is mounted to a surface of a composite workpiece and configured to transmit and receive ultrasonic energy to and from the composite workpiece during mechanical loading of the composite workpiece. An ultrasonic pulser/receiver is operatively coupled to the at least one ultrasonic testing transducer. A computing system is operatively coupled to the ultrasonic pulser/receiver. The computing system includes a data acquisition component configured to acquire data from the ultrasonic pulser/receiver and a data analysis component configured to analyze the acquired data.

Patent number: 7240556Abstract: Improved methods, systems, and apparatus for inspecting a structure using angle beam shear wave through-transmission ultrasonic signals involves positioning transducers at offset positions on opposing sides of the structure and permits inspection of the inside of the structure beneath surface defects and features. Magnetic coupling can be used for supporting a pair of leader-follower probes and defining offset positions between angle beam shear wave transducers carried by the probes. Inspection data can be collected for supporting real-time generation of three-dimensional image representations of the structure and of internal defects and features of the structure. Image generation and resolution using inspection data from angle beam shear wave ultrasonic signals can be supplemented using pulse-echo ultrasonic inspection data.Type: GrantFiled: March 14, 2005Date of Patent: July 10, 2007Assignee: The Boeing CompanyInventors: Gary E.

Patent number: 7228741Abstract: An apparatus and method aligning magnetically coupled inspection probes are provided. In this regard, a tracking probe may be magnetically coupled to a driven probe and move in coordination therewith. An alignment compensator for magnetically coupled inspection probes offsets misalignments between a driven probe and a tracking probe. Misalignments between magnetically coupled probes may be caused by gravity, friction, and movement of the probes. An alignment compensator may use one or more magnets, or electromagnets, to improve the alignment of the probes. An alignment compensator may include a control system for adjusting the power to an electromagnet or repositioning a magnet to offset misalignment of probes.Type: GrantFiled: September 16, 2004Date of Patent: June 12, 2007Assignee: The Boeing CompanyInventors: Gary E.
