Description
Summary:The introduction of Ceramic Matrix Composites (CMCs) for aircraft engines gas turbine components aims at increasing the turbine performance and in-service life on the one hand, and on the other hand saving weight, hence reducing fuel consumption. Material health control of turbine parts is an essential procedure, given the criticality of their operating performance. X-ray tomography is a particularly suitable technique for non destructive testing. However, the images produced by this 3D imaging method can be very large, making computations very time- and memory consuming, especially for characterizing complex porous materials such as CMCs. Voxaya SAS and IRT Saint-Exupery designed and tested a specific non destructive testing workflow based on Voxaya’s software, Voxilon, for the analysis of CMC engine internal parts from X-ray tomographic images. We present how Voxilon’s innovative architecture and rapid algorithms allows swiftly processing a large number of tomographic images and automatizing the sensitivity analysis of input parameters.
