1. A method of mitigating one or more of corrosion and erosion in an aircraft engine, the method comprising:
accumulating a medium inside the aircraft engine during operation of the aircraft engine and/or during a wash of the aircraft engine;
receiving usage data characterizing the medium accumulated inside the aircraft engine, the usage data including one or more characteristics of the medium indicative of an environment in which the aircraft engine was operated;
using a trained model, relating the usage data to an assigned aircraft engine condition from a plurality of aircraft engine conditions, the trained model being trained using machine learning and historical data relating characteristics of the media collected from a plurality of aircraft engines to the plurality of aircraft engine conditions; and
performing one or more of the following:
when the assigned aircraft engine condition is indicative of a corrosion risk for the aircraft engine, initiating a corrosion-mitigating action for the aircraft engine; and
when the assigned aircraft engine condition is indicative of an erosion risk for the aircraft engine, initiating an erosion-mitigating action for the aircraft engine.
