Abstract As global energy demands increase, enhancing renewable energy technologies, particularly wind turbines, is essential to meet sustainability goals. However, achieving higher efficiency remains challenging due to limitations in traditional blade designs. This study explores an innovative solution by applying biomimetic principles inspired by the Peregrine Falcon, known for its exceptional aerodynamic capabilities and high‐speed dives. The surface characteristics of the falcon's wings were transferred to a conventional NACA 0012 aerofoil to evaluate the impact on aerodynamic performance. Experimental analyses were conducted using a subsonic wind tunnel to test the bio‐inspired blade across various angles of attack and Reynolds numbers. Results demonstrated that the Peregrine Falcon‐inspired blade achieved a notable 9% increase in the lift‐to‐drag ratio compared to a traditional flat blade. The findings suggest that bio‐inspired designs can significantly improve turbine efficiency by reducing drag and enhancing lift forces. Such modifications could potentially lead to reduced operational costs and improved energy output for wind energy systems. This study highlights the potential of biomimetic design in advancing renewable energy solutions, offering a promising pathway for optimizing the aerodynamic performance of wind turbine blades.
