Computered tomography: Experimental data acquisition and parallelization of reconstruction algorithm
Non-destructive Evaluation of components is a need throughout much of the manufacturing industry that involves high value parts. The aircraft companies are a prime example of this need. The fleet of commercial and military aircraft that is in use worldwide today is aging and consequently it has become critical to develop an economical real time inspection of aircraft components such as wing structures, engine mounts, turbine blades, and various other critical components in modern day aircraft. The materials used in aircraft structures vary substantially today, indeed it is commonplace to see exotic composite materials as well as the more conventional materials such as aluminum and titanium. There are three primary methods used at the Center to do NDE inspections: (1) X-ray based, (2) Ultrasonics based, and (3) Eddy current based. Eddy currents are widely used in industry for the determination of the existence of surface cracks and their lengths in conductors. Ultrasonics is used extensively in the production and in-service inspection of composite panels for problems such as delamination and for cracks in metals. X-ray methods are used during production of composite based materials and with portable generators, for in-service detection of fatigue cracks. X-ray computed tomography image analysis of voids, cracks, and inclusions are currently finding widespread usage in both the aircraft industry and in many other industrial applications as well. Although each of these inspection types has its own merits, it is basic research into some of the X-ray based methods that will discussed in this thesis.
