Corrosion Risk Estimation and Cause Analysis on Turbofan Engine

Turbofan engine parts are subject to corrosion. This degradation is only very difficult to observe outside of engine dismantling on predefined inspection dates. On the other hand, it is necessary to go specifically to observe the impacted parts to notice this wear. This inspection process is long, expensive and rarely carried out with the aim of detecting a corrosion effect. The provision of an indicator to alert on potential corrosion and to target parts is highly anticipated. Better still, if the origin of this corrosion can be identified by numerical methods, it will then be possible to improve the calculation of the lifespan of the part and to space out engine inspections.

We offer an indicator estimating if an engine part is corroded. In addition to the alert subject to this estimate, we also offer a graphical means to interpret this detection.
