Abstract

The present paper presents the modal analyses of a NACA 4415 airfoil profiled wing.Theoretical and numerical calculations are performed by considering the aircraft wing as a cantileverbeam. The model is created and modal analyses are performed by using commercially availablepackages of SolidWorks and Ansys, respectively. The natural frequencies and the related mode shapesare obtained. The results of theoretical calculations are compared with the numerical modal analyses.The study has a conclusion that an aircraft wing can be considered as a cantilever beam that by ignoringthe whole forces on the aircraft (except for gravity).

Özet

Bu çalışmada NACA 4415 profiline sahip uçak kanadının modal analizi sunulmuştur. Uçak kanadı bir ankastre kiriş olarak düşünülerek teorik ve nümerik hesaplamalar gerçekleştirilmiştir. Kanadın modellenmesi ve modal analizi ticari paket programları SolidWorks ve Ansys ile yapılmıştır. Analiz sonucunda uçak kanadı modelinin doğal frekansı ve buna bağlı mod şekilleri elde edilmiştir. Teorik hesaplar neticesinde elde edilen sonuçlar nümerik modal analiz sonuçları ile karşılaştırılmıştır. Çalışmadan elde edilen sonuç, eğer yer çekimi kuvveti hariç diğer tüm kuvvetler ihmal edilirse, uçak kanadının ankastre bir kiriş olarak değerlendirilebileceği yönündedir.
