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.

Method of Choice: A Fluorescent Penetrant Taking into Account Sustainability Criteria

“…It also refers to changes taking place in the surroundings, as well as in technological processes [15,16,27,32,57,59,62,63], which enforce the need to search for modern methods that support the achievement of reliable FPI research. After reviewing the literature, it was concluded that the actions taken were to achieve reliable and effective fluorescent penetration inspection [10,20,21], and thus referred to the idea of sustainable development, the concept of Society 5.0 and partly the concept of Industry 4.0. These actions were mainly aiming to reduce the negative influences that fluorescent penetrants have on the natural environment [13,14,22] and reduce the human factor in the decision-making process [10,20,21].…”

Analysis of the Quality of Bearing Housing and Improving the Method of Identifying the Root of Incompatibility

“…These techniques included the fluorescent method (FPI), Ishikawa diagram and 5Why method. The choice of these techniques was conditioned on their effectiveness in identifying the incompatibility on the product in the first part of the method (fluorescent method) and, in the second part of the method, the potential causes of the incompatibility (Ishikawa diagram) and its root (5Why method) [25][26][27]. Also, the choice of the fluorescent method was dependent on the individual needs of the customer who ordered product inspection and the type of product material.…”

“…In this method, the penetrant has a colorant, so the indicators can be identified by ultraviolet radiation. To make analysis using the FPI, it is necessary to darken the test stand [28][29][30]. The method of FPI has been presented in the literature [31].…”

Improving the Non-Destructive Test by initiating the Quality Management Techniques on an Example of the Turbine Nozzle Outlet

“…It is very important in the case of the production and aviation industry, in which using the non-destructive test (NDT) is the main way to identify unconformities. These tests allow for identifying the unconformity without destroying the product [3]. One of the NDT methods is the penetration method, which includes the fluorescent method (FPI).…”

“…Also, with the FPI method the tests were performed on the analyzed product (turbine nozzle outlet). A literature review of the selected literature positions shows that the fluorescent method was used in testing the quality of a product surface [5,6] and detecting nonconformities that are the basis for further analysis [7]. Its efficiency was improved by using additional machines, substances [8] and was compared with other methods [9].…”
