Abstract
Methods and systems for mitigating corrosion and/or erosion in an aircraft engine are provided. A method includes receiving usage data characterizing a medium accumulated inside the aircraft engine. Using a trained model, the usage data is related to an assigned aircraft engine condition from a plurality of aircraft engine conditions. The trained model is trained using machine learning and historical data relating characteristics of the medium to the plurality of aircraft engine conditions. When the assigned aircraft engine condition is indicative of a corrosion risk for the aircraft engine, a corrosion-mitigating action is initiated for the aircraft engine. When the assigned aircraft engine condition is indicative of an erosion risk for the aircraft engine, an erosion-mitigating action is initiated for the aircraft engine.
