Introduction

« The introduction of ceramic matrix composites (CMC) for aircraft engine components is a significant breakthrough in the aviation industry. Being much lighter and more heat resistant than metals alloys, the use of CMCs aims at increasing both the engine fuel efficiency at high temperature and in-service life. 

Material integrity testing 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 (NDT), yet it is difficult to automatize the analysis of a series of items.

Voxaya SAS designed and tested a specific NDT workflow based on their software, Voxilon, to analyze a series of CMC engine internal parts from X-ray tomographic images. Those parts are composed of a fibrous phase and a powder phase. The aim of this study is to investigate the local flow and transport properties of the non fibrous phase. We present how we made use of Voxilon’s rapid algorithms and innovative architecture to swiftly compute these properties and automate the parameter sensitivity analysis. »
