Small-scale wind turbines (SSWTs) play a critical role in decentralized power generation, particularly in rural, remote, and off-grid regions. The aerodynamic efficiency of these turbines is primarily influenced by blade design, which governs energy capture, startup behavior, and overall system performance. This research presents a comprehensive efficiency comparison of different blade designs used in small-scale horizontal-axis wind turbines (HAWTs), including straight blades, twisted blades, tapered blades, and airfoil-optimized blades. A simulated experimental framework was developed to evaluate performance under varying wind speeds, focusing on power coefficient (Cp), tip speed ratio (TSR), torque characteristics, and energy output. Blade geometries were modeled using standard aerodynamic theory and analyzed using blade element momentum (BEM) methods. Results indicate that airfoil-optimized and twisted-tapered blade designs significantly outperform conventional straight blades, achieving higher Cp values and improved performance at low wind speeds. The findings highlight the importance of blade geometry optimization in enhancing the efficiency and viability of SSWTs for distributed renewable energy systems.The study further examines the impact of blade twist distribution and taper ratio on aerodynamic performance, revealing that gradual twist combined with tapering enhances lift-to-drag ratios. Additionally, startup torque analysis demonstrates that airfoil-optimized blades require lower cut-in wind speeds, making them more suitable for low-wind environments. These insights provide a foundation for designing SSWT blades that maximize energy capture while maintaining structural and operational efficiency.
