Abstract
Technologies for engine fluid quality monitoring are disclosed herein. An engine system includes a gas turbine engine having one or more mechanical components, a fluid quality sensing system, and an engine controller. Each mechanical component includes a tracer material embedded in the mechanical component during manufacture. The fluid quality sensing system applies a laser beam to debris captured in an engine fluid of the gas turbine engine and detects a light signature generated by tracer material in the debris in response to application of the laser beam. The engine controller identifies the tracer material as a function of the light signature. The engine controller determines a potential wear state of a mechanical component as a function of the tracer material. The engine controller may select the mechanical component from multiple mechanical components based on the tracer material. Each mechanical component has a predetermined association with a corresponding tracer material.
