Reliability of Nondestructive Inspection (NDI) of Aircraft Engine Components.
Abstract
During Phase III, on-site NDI assessments were conducted at the San Antonio Air Logistics Center at Kelly AFB, and at Oklahoma City Air Logistics Center at Tinker AFB. Assessments were performed by subjecting the representative test gas turbine engine components and specimens to production NDI procedures that are routinely applied to engine components and documenting the response/detection of each flaw in the test component. Assessments were performed and documented by methods that would support a statistically significant data sample size and would enable assessment of characteristic parameters of each NDI procedure. During Phase IV, the data were analyzed and combined to establish the baseline capabilities and reliability of NDI procedures as they were applied in production. During performance of the Phase III task, penetrant material and penetrant processing variables were identified and an off-line assessment was initiated to characterize inspection materials and processing parameters and interactions of the various parameters as a function of NDI capability. Prototype laboratory instrumentation was designed, built and utilized to process samples of penetrant processing materials that were taken at the time of assessment of each penetrant procedure. The results of the off-line processing were correlated to the probability of detection (POD) analyses and were integrated into the overall conclusions and recommendations.
