The debonds between propellant and liner seriously affect the structural integrity and working security of solid rocket motor, and reliable examination to this defect is crucial. In this paper, the research status of high energy X-rays testing technology of solid rocket motor was summarized. Based on radiography testing and industrial CT testing methods, the techniques of image analysis and defects evaluation were reviewed on debonds between propellant and liner of solid rocket motor, For this defect, the comprehensive application of radiography and industrial CT technology was presented by confirmation detection. The evaluation results showed that the reliability and accuracy could meet requirements of defect detection.
