    Abstract: A thermal inspection system is provided for a gas turbine engine hot section component with a cooling passage. This thermal inspection system includes a fluid subsystem operable to supply a fluid into the cooling passage. The thermal inspection system also includes a thermal camera subsystem operable to monitor a fluid temperate difference of the fluid exiting the cooling passage relative to the input temperature of the fluid supplied to the cooling passage.

    Abstract: A method of determining the thickness of an internal wall in a gas turbine engine component includes the steps of utilizing flash thermography to measure a complete thickness of a component between an outer wall and at least one enlarged cooling channel at a location where an outer cooling channel is positioned between the outer wall and the at least one enlarged cooling channel and where at least one member spans the cooling channel, such that the thickness is through the member which spans the outer cooling channel. An outer thickness of the component is measured from the outer wall to an outer wall of the outer cooling channel. A thickness is determined from an inner wall of the outer cooling channel to the at least one enlarged cooling channel by subtracting the measured outer thickness from the complete thickness, and also subtracting a known thickness of the outer cooling channel.

    Abstract: Apparatus and associated methods relate to predicting precursor to coating spallation. Heat is provided to a first surface of a member. A time sequence of thermal images is captured of the first surface and/or a second surface of the member. Each of the images includes a two-dimensional array of image data. Each of the image data of the two-dimensional array of image data corresponds to an xy-coordinate pair. A two-dimensional array of thermal diffusivities is calculated based on the captured time sequence of thermal images. Each of the thermal diffusivities of the two-dimensional array of thermal diffusivities corresponds to the xy-coordinate pair. Each of the calculated thermal diffusivities of the two dimensional array of thermal diffusivities are compared with a predetermined threshold. If the calculated thermal diffusivity is greater than the predetermined threshold, then precursor to coating spallation of the thermal barrier coating at the corresponding xy-coordinate pair is predicted.
