Traditional radiography is a non-destructive inspection (NDI) process widely used for the detection of cracks and damage in aircraft structures. However, there are some limitations of traditional radiography. Existing film process requires chemical processing of the film and the quality of the images varies from shot to shot. The NDI crew spends as much time going back and forth between the office, equipment storage location, and the job site as they do taking the shots, developing the film, and inspecting the shots. Operations and equipment are not standardized across aircraft systems. Complicates assigning work to X-Ray technicians. The film development process requires a significant amount of climate controlled storage space for the new and used film. Real-time radiography (RTR) allows all the benefits of producing significant increases in magnification and image clarity, as well as efficient management of digital images. Image enhancement allows more accurate interpretation of digital radiography indications. In this paper, In order to identify suitable sensors and X-ray tube to meet the high sensitivity required to inspect aircraft, different X-ray systems were evaluated. Furthermore image enhancement methods are investigated for NDI inspection of the aircraft.
