In the manufacture of head structural elements of aircraft, adhesive joints are widely used to connect the shell made of ceramic or polymer-composite material with a metal frame. During the process of implementation, there is a risk of forming defects of the “non-glued” type, which significantly reduce the strength characteristics of the adhesive joint unit and the reliability of the aircraft as a whole. In this regard, it is necessary to carry out non-destructive testing of the adhesive joint unit in assembly. The paper presents results of upgrading the existing non-destructive testing system of aircraft head structural elements by radiation methods and introducing digital radiography methods and technical means using flat-panel detectors instead of the previously used methods of radiography and fluoroscopy with the X-ray electron-optical converters. Quality of the obtained X-ray images of the adhesive joint unit of the aircraft structural element is comparatively assessed, as well as the effect of their introduction in the serial production.
