Abstract

Bu çalışmada incelenen fan-kanat, kısmen
gömülü çapraz akışlı fana (CFF) sahip olup, düşük uçuş hızları ve yüksek
manevra kabiliyeti gerektiren hava araçları için uygundur. Bu çalışmanın amacı fan-kanat
modeli çevresindeki akışın ve modele etkiyen aerodinamik kuvvetlerin TSR, Reynolds
sayısı ve AoA parametreleri ile değişiminin deneysel ve sayısal yöntemlerle
incelenmesidir. Bu amaçla BDT yazılımıyla tasarlanan deney modeli HAD
yazılımına aktarılarak akış analizinde de kullanılmıştır. HAD analizinde daimi akış kabulüyle RANS modeli MRF yöntemi kullanılarak
çözülmüştür. Hava tünelinde modelin iz bölgesinde basınç ölçümleri yapılarak
Jones yöntemi ile sürükleme/itki katsayıları elde edilmiştir. Aerodinamik kuvvetlerin direkt ölçümü
kuvvet-denge mekanizmasında
gerçekleştirilmiştir. Model yüzeyindeki
akış ayrılması iplik yöntemi kullanılarak incelenmiştir. Deney sonuçlarına göre
aerodinamik kuvvet katsayıları üzerindeki TSR etkisi Reynolds sayısı etkisine
göre daha fazladır ve yüksek TSR değerleri itki ve taşıma katsayılarını arttırmaktadır.
Artan Reynolds sayısı ile taşıma katsayısı azalırken, itki katsayısı
artmaktadır. En büyük itki katsayısı sıfır derece hücum açısında elde
edilmiştir. Fan çalışmıyor iken, model üst
yüzeyinin firar kenarına yakın bölgesinde yüksek AoA ve Re değerlerinde akış
ayrılması görülmüş, fan çalışıp TSR değeri 1’in
üstüne çıktığında ortadan kalkmıştır. HAD analizinde sıfır derece hücum açısı
ve TSR = 1,4 için farklı Reynolds sayılarında deney sonuçlarından en fazla  % 4 farklı itki katsayıları elde edilmiştir.
