Abstract – The aerodynamic efficiency of an aircraft wing significantly impacts its overall performance, including stability, fuel economy, and drag reduction. Optimizing wing designs can enhance these characteristics, improving lift generation and minimizing turbulence. This study investigates the influence of hyperbolic-shaped serrations on aerodynamic parameters by analyzing velocity and pressure distributions between a conventional wing and a serrated wing. The research employs computational fluid dynamics (CFD) simulations and wind tunnel tests to comprehensively evaluate performance enhancements.

Findings reveal that serrated wings display improved velocity stability, reduced turbulence, and lower drag, leading to superior aerodynamic performance. Enhanced boundary layer attachment minimizes flow separation, contributing to greater efficiency. The results suggest that incorporating serrations in wing designs improves the lift-to-drag ratio, making them suitable for various aviation applications.

Beyond traditional aircraft, this study's findings have potential applications in commercial and military aviation, UAVs, and wind turbines. By integrating such modifications, industries can benefit from enhanced fuel efficiency, noise reduction, and improved flight stability. Further research on optimizing serration geometries could facilitate broader adoption in aerospace engineering, paving the way for advanced aerodynamic designs.
