Title: Enhanced Bondline Inspection Using Computed Tomography (CT) for Solid Rocket Motor Aging and Surveillance
Agency: DOD
Contract: FA9300-10-C-2102
Award Amount: $735,179.00


X-ray computed tomography (CT) is used to evaluate the integrity and aging of solid rocket motors (SRM) used in missile defense. There is a need for better vizualization of bondlines of materials, and the detection of their flaws, in the dome region. This problem is due to partial volume effects inherent in all CT instruments. This project will develop and investigate algorithms and computer programs that compensate for these problems. At the core of the approach is a deconvolution algorithm that improves 3D image resolution along the axial dimension. The Phase II project will include the following work: (1) Further development of resolution-improvement (deconvolution) algorithms, (2), testing with computer simulations, an SRM analog phantom and real SRM data, (3), algorithms for visualizing dual-energy images, using both 9 and 15 MeV sources, (4), development of algorithms that correct for practical data collection imperfections that corrupt images in the forward dome,(5), installation of a prototype software/computer system at the Air Force CT Facility to serve as a testbed for field testing and feedback from users, and (6), implementation and installation of changes to the software following this feedback. BENEFIT: There are many industrial applications for X-ray CT, including the inspection of large aircraft and automobile components. Several companies, including BIR, Inc. and Carl Zeiss IMT Corp., sell X-ray CT scanners for these industries. The software may be configured as an add-on component to these products.
