Abstract
A system for preventing abnormal fan blade deflection or fan flutter includes an optical emitting source, an optical receiver, and a retroreflector for attachment to a fan blade of an engine. The system emits radiant flux from the optical emitting source towards the retroreflector when the engine is operating; receives an incident radiant flux from the retroreflector by the optical receiver; determines a deflection value of the fan blade based on the incident radiant flux received by the optical receiver; determines whether the deflection value is greater than or equal to a threshold for deflection of the fan blade to identify abnormal fan blade deflection or fan flutter; and selectively changes a state of the engine when abnormal fan blade deflection or fan flutter is identified.
