  • Method and system for monitoring rotor blades in combustion turbine engine
    Patent number: 9983576
    Abstract: In accordance with one embodiment, a method for monitoring the health of blades in a combustion turbine engine is provided. Sensors mounted around the circumference of a rotor sense and record the passage of blades during turbine operation. Analysis of information from the sensors indicates whether a blade is damaged. Analysis of blade vibration and amplitude, as measured by the sensors, is used to predict the number of cycles the blade can undergo before replacement or maintenance.
    Type: Grant
    Filed: July 18, 2016
    Date of Patent: May 29, 2018
    Assignee: FLORIDA POWER & LIGHT COMPANY
    Inventors: Paul Czerniak, Elizabeth C. Day, Paul V. Sickles
