  • Publication number: 20180156694
    Abstract: This disclosure provides systems, components, and methods for visual creep inspection of rotating components, such as those in a gas turbine. A component is provided with an external surface and an axis of rotation. The external surface has a circumference and a plurality of three dimensional reference marks forming a reference pattern along the circumference. An optical data capture device generates a data signal based on the plurality of three dimensional reference marks. A data analysis system processes the data signal to calculate a deviation in spacing of the reference pattern along the circumference and determines a strain or creep measurement.

  • Patent number: 9879981
    Abstract: A system and related methods for evaluating a component using a reference feature and a replicate of the reference feature. The component has an exterior surface with a reference feature thereon. The method includes determining an initial condition of the reference feature, subjecting the component to at least one duty cycle after determining the initial condition, determining a subsequent condition of the reference feature after the at least one duty cycle while the component is in a service position, and forming a replicate of the reference feature while the reference feature is in one of the initial condition or the subsequent condition. One of the initial condition or the subsequent condition may be determined based on the replicate of the reference feature.
