Abstract - The design and analysis of aircraft structures, particularly winglets, are critical components in the pursuit of enhanced aerodynamic performance and fuel efficiency in modern aviation. Winglets, which are the upward-curving extensions at the ends of aircraft wings, help minimize induced drag and enhance lift-to-drag ratios, ultimately leading to greater fuel efficiency and performance in flight. This study presents a comprehensive approach to the design and structural analysis of winglets, integrating advanced computational methods and experimental validation. Key design parameters, including shape, size, and material selection, are systematically evaluated to optimize aerodynamic performance while ensuring structural integrity under various loading conditions. Finite element analysis (FEA) is employed to assess stress distribution and deformation, while computational fluid dynamics (CFD) simulations provide insights into airflow characteristics and vortex behavior. The results indicate that well-optimized winglet designs can lead to significant reductions in drag and fuel consumption, with potential savings of up to 6% in operational costs. Furthermore, the study highlights the importance of balancing aerodynamic efficiency with structural considerations, ensuring that winglets can withstand the dynamic loads encountered during flight. This research not only advances the understanding of winglet aerodynamics and structural performance but also offers valuable guidelines for the development of next-generation aircraft structures that meet stringent performance and sustainability standards. The findings highlight the critical role of winglets in enhancing the efficiency and environmental sustainability of the aviation industry.
