Abstract: Cairo University, Faculty of Engineering This research presents a detailed investigation into the design of a Horizontal Axis Wind Turbine (HAWT) blade, applying advanced methodologies such as Exergy Analysis, Fatigue Analysis, and Damping Analysis. The design process began with the development of the blade geometry using optimized performance equations, followed by the use of the Blade Element Momentum (BEM) method. This method effectively integrates the principles of blade element theory with momentum theory to provide an accurate representation of aerodynamic forces. After the design was completed, Exergy Analysis was conducted to evaluate the thermodynamic performance and efficiency of the system. The Fatigue Analysis was carried out to assess the blade's resistance to cyclic stresses over its operational life. Additionally, Damping Analysis was performed to study the stability and vibrational characteristics of the blade, ensuring its long-term functionality. The findings aim to contribute to the development of more efficient and sustainable wind turbine technologies.
