Abstract

Failure(s) may be defined as the incapability of
engineering components and structures to satisfactorily perform their intended
function(s). Some of the failures of critical engineering components and
structures may be significant and lead to serious results such as accidents.
One of those critical components is aircraft main wheels. Defects may occur in
service life of these components and result in failures and affect structural
integrity and flight safety of aircraft. Therefore, defects should be detected
effectively before they cause failure of components in their service life.
These defects can be detected effectively and economically by the application
of non-destructive inspection methods. Liquid penetrant inspection method,
which is one of the non-destructive inspection methods, can be used effectively
for detecting surface discontinuities or defects in all materials except porous
ones. In this study, non-destructive inspection of main wheels of main landing
gear of small aircraft was
investigated by use
of
liquid penetrant
inspection. Some corrosion damage and cracks were detected on the wheel at the
end of liquid penetrant inspection.

Abstract

Hasar kavramı, mühendislik komponent ve
yapılarının özelliklerini yitirmeleri ile istenen işlevlerini başarılı bir
şekilde yerine getirememesi olarak tanımlanabilir. Özellikle kritik olan mühendislik
komponent ve yapılarında meydana gelen hasarların bazıları önemli olup, kazalar
gibi ciddi sonuçlara yol açabilir.  Uçak
ana iniş takımı jantları bu kritik komponentlerden biridir. Serviste
kullanımları sırasında bu kritik parçalarda hasarlanmalarına yol açabilen farklı
kusurlar oluşabilmekte ve uçakların yapısal bütünlüğünü, uçuş emniyetini
olumsuz yönde etkileyebilmektedirler. Bu yüzden bu kusurların serviste
kullanımları sırasında komponentlerde hasarlara yol açmalarından önce etkin bir
şekilde tespit edilmesi oldukça önemlidir. Bu kusurlar tahribatsız muayene
yöntemlerinin uygulanmasıyla etkin ve ekonomik bir şekilde tespit
edilebilmektedir. Tahribatsız muayene yöntemlerinden biri olan sıvı penetrant yöntemi
ile gözeneksiz malzemeler dışındaki malzemelerin yüzeye açık süreksizlikler
veya kusurlar etkin bir şekilde tespit edilebilmektedir. Bu çalışmada küçük
uçaklarda kullanılan ana iniş takımı jantlarının uçak bakım faaliyetleri
bünyesinde, sıvı penetrant yöntemi ile tahribatsız muayenesi incelenmiştir. Sıvı
penetrant yöntemi ile kontrol işlemi sonucunda bir jantta korozyon hasarı ve
çeşitli çatlak şeklindeki kusurlar tespit edilmiştir.
