Development and application of ultrasonic C-scan system for defect detection of the bonding interface between case and insulation of solid rocket motor

In order to meet the batch detection requirements for interface defects between case and insulation of solid rocket motor (SRM), an automated ultrasonic C-scan system was developed to replace the traditional manual A-scan testing. The process test and practical application show that the sensitivity and stability of the developed system can meet the batch detection requirements of this kind of products, and it has extensive engineering application value.
