- Abstract
Continuous research and development have focused on optimizing wing aerodynamics and reducing fuel consumption in air vehicles since their inception. Winglets, fixed curved structures at wingtips, gained significant attention during the oil crisis for their fuel-saving potential in the aviation industry. This study focuses on designing a morphing winglet using a shape memory alloy (SMA) for improved aerodynamic efficiency and fuel economy under various conditions. The XFLR5 software analyzes the wing's lift and drag ratios at different aircraft stages (takeoff, cruise, landing) for different cant angles. Results indicate that a moving winglet enhances the lift/drag ratio and reduces induced drag. Cant angle and angle of attack (AOA) variations play key roles in increasing this ratio. Optimal values for different aircraft stages are determined and discussed alongside existing mechanisms for moving winglets. Experimental data validation from previous studies in the literature concludes the research.
