  • System and method for monitoring health of airfoils
    Patent number: 9250056
    Abstract: A method is presented. The method includes the steps of generating rotation signals corresponding to a plurality of rotations of a rotor physically coupled to a plurality of blades, and determining peak voltages corresponding to the plurality of blades by applying time synchronous averaging technique to blade passing signals using the rotation signals, wherein the peak voltages are representative of clearances of the plurality of blades.
    Type: Grant
    Filed: December 31, 2012
    Date of Patent: February 2, 2016
    Assignee: General Electric Company
    Inventors: Prashanth D'Souza, Vivek Venugopal Badami, Rahul Srinivas Prabhu, Mahalakshmi Shunmugam Balasubramaniam, Ajay Kumar Behera, Aninda Bhattacharya, Venkatesh Rajagopalan
  • Methods and systems for monitoring health of blades
    Patent number: 9250153
    Abstract: A system is disclosed. The system includes a processing subsystem that determines preliminary voltages corresponding to a plurality of blades based upon blade passing signals (BPS), and generates a plurality of clearance values by normalizing the preliminary voltages for effects of one or more operational parameters, wherein the plurality of clearance values are representative of clearance of the plurality of blades.
