Abstract
A system for fan stress tracking according to an example of the present disclosure includes, among other things, a computing device that has a memory and a processor. The computing device is operable to execute a data module and a comparison module. The data module is operable to access data corresponding to a sensed value of an engine inlet parameter, and is operable to access data corresponding to a fan stress fatigue ratio profile. The fan stress fatigue ratio profile is defined with respect to at least one fan blade. The comparison module is operable to associate the sensed value of the engine inlet parameter with a stress value according to the fan stress fatigue ratio profile. The comparison module is operable to determine whether the stress value meets at least one predetermined criterion.
