摘要

摘要本文的目的是评估数字射线照相术检测米格-29垂直稳定器内部结构裂纹的能力。测试对象是一个稳定器，之前进行了疲劳测试，并为了目视检查的需要而部分拆除。使用脉冲x射线发生器和数字探测器阵列对含有裂纹零件的三个区域进行了检查。结果证实，该方法可用于检测内部结构中的裂纹，而其他方法无法在不影响稳定器完整性的情况下对其进行检查。

Application of Digital Radiography (Dr) in an Approach to Evaluate the Technical Condition of MiG-29’s Vertical Stabilizers

Abstract The purpose of the work presented was to evaluate the capabilities of digital radiography to detect cracks in the internal structure of MiG-29 vertical stabilizers. The test object was a stabilizer previously subjected to fatigue testing and partially torn down for the needs of visual inspection. An inspection of three regions containing cracked parts was performed, with use of a pulsed x-ray generator and digital detector array. The results confirmed the method could be used to detect cracks in an internal structure which could not be inspected with other methods without affecting the stabilizer’s integrity.
