“…A paper presented at the INTERMAG-MMM conference in July, 1988 proposes an automated method for estimation using eddy current image data where the material being tested is magnetic [1]. These estimates are within two to one of the correct results over a wide range of EDM slot sizes and aspect ratios, provided the slot length is at least half the mean coil radius.…”

“…he process is also relatively slow [11] . For some parts, such as mounting holes [9] or turbine rotors [10] , it is easier for the ECT process to be automated. However, for testing other parts, such as turbine blades, the detection process of the ECT is still ineicient.…”

“…his current generates another magnetic ield and the inductance caused by this magnetic ield is measured to detect defects. ECT is highly sensitive to surface or near-surface defects and it can automatically inspect special structures using well-designed probes [9][10][11] . Automated ECT on turbine blades is presented in [11] .…”

Design of an advanced automatic inspection system for aircraft parts based on luorescent penetrant inspection analysisNon-destructive testing (NDT) of aircraft parts has become increasingly important in improving the safety and reliability of the aerospace industry, especially in the testing of high-temperature and high-pressure turbine engine parts. Among the various types of NDT methods available, luorescent penetrant inspection (FPI) is comparably more cost-eicient and is widely used in NDT on aircraft parts. However, current FPI still requires considerable labour forces in its processing, inspection and analysis procedures. In this paper, we have developed an advanced automatic inspection system (AAIS) that uses image processing and pattern recognition techniques to aid human inspectors. The system can automatically detect, measure and classify discontinuities from the FPI images of aircraft parts. Tests have been performed on the sample images provided by our industrial partners to evaluate our developed AAIS. The test results demonstrate that the developed system has signiicantly improved the eiciency of FPI with satisfactory accuracy.
