4.1 Fault detection

Sinton and co-authors have used NMRI to analyze defects in diluents and plasticizers, as well as propellant distribution in solid rocket fuels. The non-uniform distribution of these components and other defects can lead to combustion instabilities affecting rocket flight reliability. A short echo time in ¹ H Fourier imaging is sensitive to distribution defects in both diluent and plasticizer. Multislice imaging of ²⁷ Al was used for fuels loaded with metallic aluminum...
