In a continuing effort to enhance the performance of small wind energy systems, one root airfoil and three primary airfoils were specifically designed for small horizontal axis wind turbines. These airfoils are intended primarily for 1–5 kW variable-speed wind turbines for both conventional (tapered/twisted) or pultruded blades. The
Small horizontal-axis wind turbines (HAWTs), which according to the standards issued by the International Electrotechnical Commission are characterized by a rotor swept area of less than 200 m 2, rely on the same aerodynamic principles governing the operation of larger HAWT systems.
The literature review reveals that the aerodynamic performance of small wind turbines is sensitive to wind conditions, atmospheric turbulence and local
However, a number of different styles/types of turbines exist and the way in which they harness kinetic energy from the wind is quite different. The two main types of turbines are Horizontal-axis Turbines (HAWT) and Vertical-axis turbines (VAWT). HAWT have the rotating axis oriented horizontally. They typically feature 3-blades and are

Wind turbines harness the wind''s kinetic energy and convert it to electricity. Large horizontal axis wind turbines (HAWT) are typically located on the outskirts of cities, near the seashore, or offshore in the ocean. For urban areas, small HAWTs are preferred compared with their counterparts. HAWTs are often constructed
