Abstract

Ice accretion on unmanned air vehicle’s wing modifies the initial airfoilcontour and changes the aerodynamic characteristic of the wing. The aimof this research is to calculate performance losses on a wing due to theaccretion of rime ice. In this study, ice formation on NREL S826 airfoil ispredicted by using ice accretion tool. The computed aerodynamic loads arecompared for clean wings and iced wings with different aspect ratios. Thecomputations are based on the lifting-line method. According to the results,predicted aerodynamic performance loss is higher for small aspect ratiothan that of the bigger for the rime ice.

Özet

İnsansız hava araçları kanat profili üzerinde oluşan buzlanma başlangıç kanat profilini değiştirerek, kanadın aerodinamik karakteristiğini değiştirir. Bu çalışmanın amacı, buzlanma oluşumundan dolayı bir kanattaki performans kayıplarını hesaplamaktır. Bu çalışmada NREL S826 kanat profili üzerindeki buz oluşumu, buz birikim hesaplama aracı kullanılarak tahmin edilmektedir. Hesaplanan aerodinamik yükler, farklı açıklık oranlarına sahip temiz ve buzlu kanatlar için karşılaştırılmıştır. Hesaplamalar taşıyıcı çizgi yöntemine dayanmaktadır. Karsı tipi buzlanma koşullarında elde edilen sonuçlara göre, tahmin edilen aerodinamik performans kaybı küçük açıklık oranına sahip kanat için daha yüksektir.
