Uçan Kanat Tipi İHA'larda Kanat Profillerinin Aerodinamik Performans Karşılaştırması

The aim of the study is to investigate how choice airfoil affects aerodynamic characteristics a flying wing UAV. For this purpose, comparative analyzes were performed for four different airfoils: MH60, TL54, Eppler 339, and TsAGI 12%. Given maximum range performance (maximum lift /drag ratio), best efficiency given by UAV with MH60 TL54 airfoil. Based on their lift-to-drag ratio, UAVs made airfoils exhibited efficiency. Specifically, ratio was 33.1, while that 32.7. Considering pitching moment coefficient, 12% more stable characteristic than 339 airfoils. results study, it found outperformed those in terms range, minimum descent rate, endurance performance.
