TURBINE ROTOR HEALTH MANAGEMENT WITH BLADE-TIP SENSORS: FROM LABORATORY TOOL TO FIELDED SYSTEM

摘要

The current state of prognostics and health monitoring of gas turbine engine rotor blades is outlined. Differences in high cycle fatigue and low cycle fatigue prognostics approaches are noted. A maturation plan to get from a laboratory development system to an autonomous prognostics and health monitoring system is described. This plan addresses issues of algorithm maturation, system architecture, data storage, processor selection, and early refinement in a fleet.
