Çırpan kanadın aerodinamik parametrelerinin deneysel olarak incelenmesi

Öz

İnsansız hava araçlarının kullanım alanlarının artması bu alanda yapılan çalışmaların sayısını artırmıştır. İnsansız hava araçlarının daha küçük modelleri olan mikro hava araçları sivil ve askeri birçok alanda kullanılmaktadır. Mikro hava araçları temel olarak sabit, döner ve çırpan kanatlı olarak üçe ayrılır. Bu çalışmada incelenen çırpan kanatlı hava araçlarının en önemli avantajı, itki kuvvetinin kanatların çırpma hareketi sonucu oluşur ve böylece harici bir itki sistemine ihtiyaç duyulmaz. Bu çalışmanın amacı çırpan kanatlardaki daimi olmayan akışı rüzgâr tünelinde deneysel olarak incelemektir. Çalışma kapsamında bir çırpan kanat mekanizması oluşturulmuş ve farklı malzemelerden üretilen kanatlar çırpma hareketi yaparken farklı hava hızı, hücum açısı ve çırpma frekanslarındaki aerodinamik parametreleri incelenmiştir. Elde edilen sonuçlara göre; yüksek hava hızı ve hücum açılarında taşıma kuvveti artarken, sürtünmenin artmasından dolayı itki kuvveti azalmaktadır. Yüksek çırpma frekanslarında itki kuvveti artarken taşıma kuvveti azalmıştır. Malzeme açısından değerlendirilirse, naylon ve lateks kanadın itki kuvvetlerinin ahşap kanattan daha iyi olduğu tespit edilmiştir.
