根据固体发动机的结构和生产工艺，将发动机燃烧室射线检测缺陷分为8大类14小类。对传统的底片判读原则进行了发展，提出了针对固体发动机的“位置-形状-密度”影像评判方法，并对衬层与药柱脱粘缺陷进行了验证性分析。最后，给出了部分缺陷的工业 CT 或射线照相典型影像，对于指导固体发动机射线检测缺陷评定具有一定的经验价值。%According to structure and production engineering of solid rocket motor (SRM), defects of chamber were classified into 8 groups and 14 categories. Based on traditional method of film assess, this paper presents location-geometry-density defects evaluating method, and analyzes liner-propellant debonding through it. Finally, some typical defects images of CT and radiography were given, which were experiences to nondestructive testing personnel of SRM.
