  • System and method for detecting spall within a turbine engine
    Patent number: 10132688
    Abstract: In one embodiment, a system includes a multi-spectral pyrometry system configured to receive a broad wavelength band radiation signal from a turbine component, to split the broad wavelength band radiation signal into multiple narrow wavelength band radiation signals, to determine emissivity of the turbine component based on the narrow wavelength band radiation signals, and to detect spall on a surface of the turbine component based on the emissivity.
    Type: Grant
    Filed: December 17, 2010
    Date of Patent: November 20, 2018
    Assignee: General Electric Company
    Inventors: Jordi Estevadeordal, Guanghua Wang, Lucy Joelle Summerville, Nirm Velumylum Nirmalan
  • System for providing cooling and purging air flow to a rotary machine online monitoring system
    Patent number: 8727706
    Abstract: In one embodiment, a system includes a sight tube configured to optically communicate with an interior of a rotary machine via insertion within an inspection port. The sight tube includes a window and multiple openings configured to direct purge air across the window. The system also includes a curtain tube disposed about the sight tube and configured to direct purge air from a first air source to the openings via a first passage formed between an inner surface of the curtain tube and an outer surface of the sight tube. The curtain tube includes multiple outlets configured to direct curtain air around the window, and the curtain tube is configured to direct the curtain air from a second air source to the outlets via a second passage formed between an outer surface of the curtain tube and an inner surface of the inspection port.

  • System and method for rotary machine online monitoring
    Patent number: 8431917
    Abstract: In one embodiment, a system includes an optical monitoring system configured to optically communicate with an interior of a rotary machine. The optical monitoring system is configured to redirect a field of view toward different regions of a component within the interior of the rotary machine while the rotary machine is in operation, and to capture an image of each region.
