This paper deals with automated non-destructive testing ultrasonic systems integrated into aircraft composite production plants mainly for military and commercial aircraft components. These systems are dedicated to non-destructive testing of aircraft components made of composite materials like GLARE, GFRP and CF. The applied inspection technology is mainly through transmission technique using water squirters. Additionally bubbler technology for precise pulse echo technique and multi channel acquisition is used. Two main requirements are to be fulfilled: Fast inspection using high inspection speed and/or multi channel inspection systems. High resolution and reliability using sensitive and state of the art UT equipment and precise mechanical scanner or linear robot systems, also for 3 dimensionally curved parts. In this paper, specific applications of different system layouts are presented. The systems presented provide state-of-the-art technology for inspecting aircraft components for different applications, mainly for complex geometrical requirements and high reliability. All technological disciplines like advanced mechanics and motion controls as well as UT-equipment and data acquisition and evaluation system have been upgraded for advanced capability. In a next step, Phased Array Technology will be integrated for multi channel application and parallel B-scan. This new technology integration will further enhance detection capability and throughput.
