X-Ray Computed Tomography for Aerospace Components.

摘要

This document contains a study of the optimization of certain parameters of computed tomography systems for inspection of aerospace components, in general, and solid propellent rocket motors, in particular. The report consists of a series of computer simulations and empirical measurements which treat specific cases of appropriate phantoms. The phenomena of beam hardening and scattering, which can occur extensively in high energy, industrial tomography, are investigated in detail. The primary finding is that computed tomography appears to be a feasible, new method for non-destructive inspection of rocket motors. (Author)
