Abstract:

Owing to limitations of X-ray film method and X-ray real-time imaging method in inspection of solid rocket motor, this paper introduces the industrial CT system for solid rocket motor evaluation which has excellent NDE performance.The principle for the system to produce the density distribution image of a thin motor slice, the popular imaging reconstruction methods and the basic formation and essential parts of the system are deduced and elucidated briefly. Comments of the system on performance to inspect motors and ability to find various defects of the motor as well as the discussion of system merits and demerits are given. In addition, the paper describes in short length the general developing survey, characteristic and recent tendency of the industrial CT system for solid rocket motor evaluation.
