Description

The RFC Inspection System uses eddy current and ultrasonic techniques to perform automatic inspection of gas turbine engine components. Current flaw size requirements are 0.010 inch (length) x 0.005 inch (depth) surface connected cracks and 0.020 inch diameter penny shaped, mal-oriented internal voids. Successful and reliable detection of these small flaws requires sophisticated inspection equipment and techniques. Details of both the eddy current and ultrasonic inspections will be presented along with the philosophy and reasons supporting each component of the inspections. Inspection components presented will include: part dimensioning, probe calibration, adaptive scanning, threshold detection, signal processing, and flaw position correlation. Additional material will be presented highlighting the problems and solutions associated with a sophisticated, automatic inspection system.
