In order to ensure the safety of passengers and the normal maintenance of the equipment, it is necessary to perform surface impact damage detection on the components and structures of the aircraft. For a long time, the detection of complex aerospace components has been a problem that has plagued aircraft manufacturers and airlines. For example, aircraft turbine engines, engine rooms, engine cabins and cockpits are all extremely complex and cannot be removed. Detected assembly assembly.
Phased Array Detection and Imaging (PA) is an advanced ultrasonic inspection (UT) method that is widely used in NDT inspection. Phased array focus law simulation predicts test results, optimizes probe and wedge configuration. The use of 2D matrices makes it difficult to detect complex shape components. Due to the lack of a better solution, CAD files or theoretical model structures are often used to build 3D models. However, the true component shape is often far removed from the theoretical model and therefore affects the quality of the ultrasound scan and the probability of detection.
For aerospace components with complex geometries, combined with 3D component modeling and phased array inspection technology, the damage can be highly accurately demonstrated. With the 3D scan data acquired by the CreaformNDT device, the aerospace maintenance team can obtain the positioning and quantitative information needed for phased array ultrasonic testing. These data are indispensable for the development of appropriate maintenance, repair and overhaul (MRO) programs.
