Improved NDE (Non-Destructive Evaluation) Capability for Aerospace Components

摘要

The potential application of high resolution computed tomography (tomoscope) to non-destructive evaluations of aerospace components has been investigated. Trade-off studies of potential scan modes identified rotate-only scanning with a fiber-optic/Reticon Detector (SFRD) as the optimal approach to practical operation. Experimental studies of a microfocal x-ray source and the SFRD pinpointed current problems and capabilities. A conceptual design was developed as a recommended implementation of this technology. Concurrent source and prototype development was recommended as an appropriate approach to developing this technology.
