Non-Destructive Testing is Key
Non-destructive testing of a landing gear housing
The systems and components by Liebherr-Aerospace Lindenberg GmbH, Lindenberg (Germany) are made of a variety of materials. They undergo a wide range of processes and diverse treatments to meet the high requirements for use in aircraft in terms of density, temperature and pressure. Our non-destructive testing methods are certified according to Nadcap, i.e. they meet the strict uniform quality standard worldwide in the aerospace industry.
Non-destructive material testing uses different procedures for materials, geometries, manufacturing processes and requirements before, during and after the production process. Whether plastic, iron, non-ferrous metals or composite materials - the complete variety of product technology is reflected in the knowledge of the required test methods. For all materials and processes, the appropriate tests are carried out quickly, effectively and flexibly, and even the finest pores or material deviations can be detected. In doing so, we continuously ensure high product quality without destroying the component.
Examination of a valve block
Continuous training is required of all our test personnel - even at the highest level of education (Level III qualification) - to introduce new technologies and special techniques used in aeronautical engineering and to meet special requirements, such as to qualify customer-specific additional training. Our test staff have e.g. completed customer training for high-temperature and high-pressure components for future engine programs with Aerospace Transmission Technologies GmbH (ATT) - a joint venture between Rolls-Royce and Liebherr. The test methods are continuously adapted in order to optimize the production processes at the highest level.
At our facility In Lindenberg, we use in addition to the seven different standard NDT methods magnetic particle examination, fluorescent penetration test, natal etching process, eddy current testing, visual inspection, ultrasonic, X-ray inspection and special procedures such as the Barkhausen technology and X-ray diffractometry.
