Abstract: Systems and methods for validating an inspection software are provided. A dataset which defines properties for a three-dimensional component having at least one known defect is obtained. The three-dimensional component is inspected with the inspection software using the dataset to obtain inspection results for the three-dimensional component. The inspection results are compared to reference results for the three-dimensional component. When the inspection results correspond to the reference results within a predetermined threshold, a signal indicative of validation of the inspection software is issued.

Abstract: Methods and systems for characterizing holes in a combustor liner of a gas turbine engine, and associated repair methods are provided. One method comprises receiving first measured data of the combustor liner in an uncoated state. The method includes determining a first location and a first orientation of a first hole and a first location and a first orientation of a second hole in the combustor liner using the first measured data.

The characterization of the holes may be used to re-drill the obstructed second hole.

Abstract: The present disclosure relates to methods and systems for measuring a component. First measurements for a plurality of features of the component are obtained from a first measurement instrument. Second measurements for at least one of the plurality of features of the component are obtained from a second measurement instrument, the second measurement instrument having a higher measurement resolution than the first measurement instrument. A scaling factor for the at least one of the plurality of features, which relates the first measurements to the second measurements, is determined. Scaled measurements for the plurality of features of the component are generated by applying the scaling factor to the first measurements. The scaled measurements are output as measurements of the component.
