METHODS AND SYSTEMS FOR MONITORING HEALTH OF BLADES

摘要

PROBLEM TO BE SOLVED: To provide a system and method that may predict health of airfoils in real time.SOLUTION: A system 10 includes a processing subsystem 16 that determines preliminary voltages corresponding to a plurality of blades 12 on the basis of blade passing signals, and generates a plurality of clearance values by normalizing the preliminary voltages for effects of one or more operational parameters, where the plurality of clearance values are representative of clearance of the plurality of blades 12.
