SYSTEM AND METHOD FOR DIAGNOSING A CONDITION OF AN ENGINE

A method (300) for diagnosing a condition of an aircraft engine (10) comprises obtaining a sample of lubricating fluid (126) from the engine (10), filtering the sample (126) to obtain a plurality of particles (124) from the lubricating fluid, directing an excitation beam towards the particles (124),...

Summary:A method (300) for diagnosing a condition of an aircraft engine (10) comprises obtaining a sample of lubricating fluid (126) from the engine (10), filtering the sample (126) to obtain a plurality of particles (124) from the lubricating fluid, directing an excitation beam towards the particles (124), detecting an energy level (Qm) emitted from the particles (124) in response to the excitation beam, determining a level of coking in the lubricating fluid based on a difference between the energy level as detected (Qm) and an expected energy level (Qe), and diagnosing a condition of the engine (10) based on the level of coking in the lubricating fluid.
