Uçaklar servise verildikten sonra, farklı çalışma koşullarına ve birçok gerilime maruz kalır. Bu nedenle uçaklarda kullanılması için mukavemeti yüksek ve esneyebilen malzemeler seçilir. Ayrıca malzemelerin yüksek çekme ve basma dayanımı, korozyon direnci gibi özellikleri de göz önünde bulundurulur. Bir uçağın bakımı, uçağın üretim sürecinden itibaren başlar ve uçağın kullanıldığı son tarihe kadar yapılır. Bu bakımların amacı uçağın ve uçak komponentlerinin yapısal ve fonksiyonel performanslarını ilk günkü gibi korumaktır. Uçağın ve uçak komponentlerinin düzenli bakımları yapılmalıdır. Halihazırda kullanılan tahribatlı testler ile çok küçük çatlaklar tespit edilememektedir. Ayrıca bu yöntemler malzeme yapısına zarar verebilir. Bu olumsuzlukların üstesinden gelebilmek için tahribatsız muayene yöntemleri kullanılmaktadır. Tahribatsız muayene bilimi, malzeme kontrollerinin öncesinde ve sonrasında farklı teknik işlemler kullanılarak gerçekleştirilen çalışma alanıdır. Tahribatsız muayene medikal, polimer sektörü, havacılık alanı gibi geniş alanlarda kullanılmaktadır. Bu yöntemler sayesinde, sistemlerin ve malzemelerin özellikleri etkilenmeden kontrolleri yapılabilmektedir. Ayrıca tahribatsız muayeneler ile uçak bakımında darbe hasarı tespit edilebilir ve onarım veya sadece hata izleme şeklinde kararlar alınabilir. Bu çalışmada bir uçak komponentinin sıvı penetrant, gözle kontrol (boroskop, büyüteç, fener, ayna, komparatör vb.) ve ultrasonik kontrol yöntemleri ile kontrolleri yapıldı. Bu yöntemler kullanılarak test numunesinin üzerindeki hata ve kusurlar tespit edildi. Bu testler yapılırken ele alınan uçak komponentinin zarar görmemesi ve doğru sonuçlar elde edilebilmesi için en uygun muayene yöntemi belirlendi ve ilgili yöntemlerin kullanım açısından mukayesesi yapıldı.
After the aircraft are served, they are exposed to different working conditions and many tensions. Therefore, for use in aircraft, high strength and folding materials are selected. Also high drawing and printing resistance of materials, corrosion resistance, and other characteristics are considered. The maintenance of an aircraft begins from the production process of the aircraft and is carried out until the last date of use of the aircraft. The purpose of these maintenance is to maintain the structural and functional performance of the aircraft and components as the first day. The aircraft and aircraft components must be kept regularly. Very small fractures cannot be detected with the damaged tests that are already used. Also, these methods can damage the material structure. Untouchable methods are used to overcome these disadvantages. Non-destructional inspection science is the field of work carried out using different technical processes before and after material inspections. Non-destructive examination is used in widespread areas such as medical, polymer sector, aviation sector. Through these methods, controls can be done without affecting the characteristics of systems and materials. It is also possible to detect accidental damage in aircraft maintenance with non-destruction inspections and to make decisions in the form of repair or just error monitoring. In this study, the liquid penetrant of an aircraft component, eye control (boroscope, amplifier, lamp, mirror, comparator, etc.) It has been controlled by ultrasound control methods. The use of these methods identified errors and defects on the test sample. The most appropriate method of testing was determined in order to ensure that the component of the aircraft that was dealt with was not damaged and the correct results were obtained and comparison of the relevant methods was made in terms of use.
After the aircraft are put into service, they are subjected to different operating conditions and many stresses. For this reason, materials with high strength and flexibility are selected for use in airplanes. In addition, the properties of the materials such as high tensile and compression strength, corrosion resistance are also taken into consideration. Maintenance of an aircraft starts from the production process of the aircraft and is done until the last date the aircraft is used. The purpose of these maintenance is to preserve the structural and functional performance of the aircraft and aircraft components as on the first day. Regular maintenance of the aircraft and aircraft components should be carried out. Very small cracks cannot be detected with the destructive tests currently used. In addition, these methods can damage the material structure. Non-destructive testing methods are used to overcome these negativities. Non-destructive testing science is a field of study performed using different technical processes before and after material controls. Non-destructive testing is used in wide areas such as medical, polymer industry, aviation field. Thanks to these methods, controls can be made without affecting the properties of systems and materials. In addition, with non-destructive inspections, impact damage can be detected in aircraft maintenance and decisions can be made in the form of repair or just defect tracking. In this study, an aircraft component was controlled by liquid penetrant, visual inspection (borescope, magnifier, flashlight, mirror, comparator etc.) and ultrasonic control methods. Using these methods, defects on the test sample were detected. While performing these tests, the most appropriate inspection method was determined in order not to damage the aircraft component and to obtain accurate results, and the related methods were compared in terms of usage.
