More Information
Summary: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.
