Multi-view radiation imaging: new opportunities of testing the internal structure of solid propellant propulsion systems

This research is dedicated to one of the most complicated types of NDT, i.e. the position determination of structural components in model and full-scale propulsion systems. The X-ray imaging systems are a single source of information on the coordinates of a surface under conditions of test firings. A novel technique for reconstruction of 3D coordinates using both data on a rotation angle of a propulsion system and elements of differential geometry was presented. The technique has been confirmed by the findings of theoretical, numerical and full-scale simulations. For the user of radioscopic systems, these studies will render assistance in simulating results for propulsion systems of various designs when selecting the system parameters and X-ray geometry.
