Kanat yapısal özellikleri operasyon giderlerini de doğrudan etkiler. Kanat performansını iyileştirmek havacılığın doğuşundan bu yana bir amaç olmuştur. Günümüzde bu alan araştırmacılara geniş bir çalışma sahası imkanı sunar. Bu alanda yapılan çalışmaların kayda değer bir kısmı kanat burulmasının etkilerini incelemeye yöneliktir. Kanat burulmasının, yani burulma açısının kanat performansını olumlu etkilediği ve kanadın stall karakteristiğini değiştirdiği bilinmektedir. Bu makalede düşük hızlı bir kanat profili kullanılarak üretilen model kanatlarda burulma açısının kanat aerodinamik performansına ve yüzeydeki basınç dağılımına etkilerinin sonuçları ele alınmıştır. Çalışmada düşük Reynolds sayıları için uygun olan SD7037 kanat profili kullanılarak burulma açıları farklı olan 5 kanat modeli üretilmiştir. Çalışmalar 2x105 Reynolds sayısında gerçekleştirilmiştir. Modeller üzerinde kritik noktalara basınç delikleri açılmıştır. Deneyler -10° ile 35° arasında değişen hücum açılarında gerçekleştirilmiştir. Burulma açısının etkileri testleri yapılmış bir rüzgar tünelinde deneylerle ortaya araştırılmıştır. Deneyler sonucunda modellerin taşıma performansları ve kanat üst yüzeyindeki stratejik noktalardaki basınç dağılımları elde edilmiştir. Elde edilen veriler grafikler halinde verilip yorumlanmıştır.</p></abstract>

                            <p>In order to establish a safe flight, the structural features of the wing must be well examined. Wing structural features also directly affect operating costs. Improving wing performance has been a goal since the dawn of aviation. Today, this field offers researchers a wide range of study opportunities. A significant part of the studies in this area are aimed at examining the effects of wing twist. It is known that wing twist, that is, twist angle, positively affects wing performance and changes the stall characteristic of the wing. In this article, the results of the effects of twist angle on wing aerodynamic performance and pressure distribution on the surface are discussed in model wings produced using a low-velocity airfoil. In the study, 5 wing models with different twist angles were produced by using the SD7037 airfoil, which is suitable for low Reynolds numbers. The studies were carried out in the 2x105 Reynolds issue. Pressure holes are drilled at critical points on the models. The experiments were carried out at angles of attack ranging from -10° to 35°. The effects of twist angle were investigated by experiments in a tested wind tunnel. As a result of the experiments, the lifting performance of the models and the pressure distributions at strategic points on the upper surface of the wing were obtained. The obtained data were given and interpreted in graphs.</p></trans-abstract>
