A Maintenance-Oriented Assessment on Aging and Deterioration of Aircraft Cable System

Year 2019, Volume: 60 Issue: 694, 1 - 9, 19.03.2019

Abstract

The aging of electrical wiring interconnection systems (EWIS), a maintenance-focused assessment was conducted to determine the level of deterioration of the wire bundles/harness. In a typical aircraft, hundreds of thousands of cables are used to fulfill many functions. Failures that may occur in the cable system can lead to high cost maintenance and dangerous circumstances. Thus, Cable thus inspections thus have a significant place in aircraft maintenance. Factors, such as vibration, moisture, metal chips, indirect damage, contamination and excessive temperature, occurring in the cable system are the main causes of the degradation. In this study, the deteriorations of the cable system and the cable bundles were determined and in the scope of the MIL-HDBK-525 on the cable system, the risks of the analysis obtained in associated with general visual inspection (GVI), detailed inspection (DET) and zonal inspection (ZI) which covers a combination of GVI and DET were evaluated.

Uçak Kablo Sisteminde Meydana Gelen Yaşlanma ve Bozulmaların Bakım Odaklı Değerlendirilmesi

Year 2019, Volume: 60 Issue: 694, 1 - 9, 19.03.2019

Abstract

Uçak elektrik kablo bağlantı sistemi yaşlanması üzerine olan bu çalışmada, kablo demetlerindeki bozulma seviyesini belirleyen bakım odaklı bir değerlendirme yapılmıştır. Tipik bir uçakta çok sayıda fonksiyonu yerine getiren yüzbinlerce kablo kullanılmaktadır. Kablo sisteminde yaşanabilecek arızalar yüksek maliyetli bakımlara ve tehlikeli durumlara neden olabilmektedir. Bu yüzden, uçak bakımında kablo incelemeleri önemlidir. Kablo sisteminde oluşan titreşim, nem, metal talaşları, dolaylı hasar, kirlenme ve aşırı sıcaklık gibi faktörler bozulmanın başlıca nedenlerindendir. Bu çalışmada, kablo sisteminde ve demetlerinde oluşan bozulmalar ve seviyeleri belirlenmiş ve MIL-HDBK-525 kapsamında, genel görsel muayene, ayrıntılı inceleme ve bunların bir kombinasyonunu kapsayan bölgesel incelemesine ilişkin elde edilen analizlerin riskleri değerlendirilmiştir.
