High aspect ratio wings have been the focus of recent aircraft designs for improving fuel efficiency through induced drag reduction. The lengthened wingspan derived from these designs have led to the development of innovative wingtip devices to mitigate the associated aerodynamic penalties. This research aims to investigate the dynamic behavior of high aspect ratio wings with various wingtip configurations, with a focus on understanding the complex interactions between the wing and the surrounding airflow. The study will employ a combination of computational fluid dynamics (CFD) and wind tunnel testing to analyze the aerodynamic performance of different wingtip designs, with a view to identifying the most effective configurations for reducing drag and improving overall aircraft efficiency.
