Abstract

Aerodinamik, delta kanatlar ve mikro hava araçları (MAVs) de dahil olmak üzere basitleştirilmiş modeller ile temsil edilebilen insansız savaş hava araçlarında (UCAVs), son yıllarda önemli bir yer almıştır. Delta kanatlar üzerinde oluşan girdap dinamiği ve bu girdapsal akışın kanadın performansına etkileri kilit bir rol haline gelmiştir. Bu çalışmanın amacı düşük süpürme açısına sahip delta kanat (Λ = 510) üzerinde oluşan akışın fiziğini ve aerodinamik performansını boya görüntüleme ve kuvvet ölçüm sistemi kullanarak anlamaktır. Farklı hücum açılarında, 50 ≤ α ≤ 300, girdapsal akışın yapısı, girdap çökmesi ve akış ayrılmasının görüntülenmesi, aerodinamik kuvvetler olarak kaldırma ve sürüklenme kuvvetlerinin statik durumda incelenmesi araştırılmıştır.

Kuvvet ölçümleri ve boya görüntülemesi su kanalında delta kanat modelinin akış karakteristiğini açıklamak için gerçekleştirilmiştir. Deneysel çalışma aerodinamik performansı anlamak için farklı hücum açılarında boya görüntülerinin, kaldırma ve sürüklenme kuvvet katsayılarının zaman ortalamalarını ihtiva etmektedir. Girdap çökme noktası, düşük hücum açılarında kanadın firar kenarında daha uzakta oluştuğu görülmüştür. Sonuçlar aerodinamik kaldırma ve kuvvet katsayılarının hücum açısının değişimi ile güçlü bir şekilde girdap etkileşimlerinden etkilendiğini göstermektedir. CL, ve CD de farklı hücum açılarında girdap çökmesi ve ölü akış koşullarından etkilenmektedir.
