Abstract

The United States Air Force has an initiative for technology development and implementation in design, production, acceptance and maintenance overhaul operations. As a part of this initiative, an x-ray computed tomography capability was acquired for use in the support of aircraft structures and gas turbine engine overhaul applications at Kelly Air Force Base, Texas. Implementation of the technology into the Kelly work flow has required acquisition of the knowledge and skills required to use the system, and re-analysis of work functions to assess added capability, measurement precision, reliability and productivity. At the same time, the nature of the data / information output from the system has offered opportunity to analyze data, extract information and make decisions in a way that was not previously possible. For example, image analysis, information extraction and decision processing which had been previously performed by manual reading of film x-radiographs was now available in electronic form and could thus be processed using automated tools. A task was initiated to interface the output from the computed tomography (CT) system to an “Automated Nondestructive Evaluation System” (ANDES) being developed under contract to the Air Force, Phillips Laboratory (REF 1) to provide a user driven information extraction and decision processing capability for use on nondestructive evaluation (NDE) data. Pre-screening and data interface to a defined format are required as inputs to the ANDES system. Since data from the CT system are provided in a reconstructed image form, an image processing / information extraction capability was required to provide the interface link to the ANDES system
