摘　　要：针对机载固体火箭发动机多层复合结构粘接质量检测问题，利用聚焦探头双模式检测方法，研制开发了一套适合直径Ф90-Ф250mm，最大长度2000mm，且圆柱表面有凸起物的各种空-空导弹火箭发动机多层包覆质量自动超声图像诊断系统。可通过一次C扫描获得多层包覆不同界面粘接质量诊断图像，其脱粘检测分辨力不大于Ф5mm。Aiming at bonding quality detection problems of multilayer coating structure for the airborne solid rocket motor, an automatic ultrasonic image diagnosis system was developed by using double-mode focused probe detection method. The system is suitable for bonding quality detection of varions air-w-air missile rocket motors with diameter within Ф90 - Ф250 mm, total length less than 2 000mm,and some pretruding things on the case surfae. Through one C-scan, bonding quality images among different interfaces of multilayer coating structure were obtained, and debond inspection resolution power is less than Ф5 mm.
