3. Introductin Airfoil , the cross-sectional shape of wind turbine blades, are the foundation of turbine blade designs. Generating lift and drag when they move through the air. Airfoils play a key role in improving the aerodynamic performance and structural durability of a turbine’s blades.

4. parts(sections) 1. Leading Edge: The front part of the airfoil where air hits first. 2. Trailing Edge: The back part of the airfoil where air leaves. 3. Chord Line : A straight line joining the front (leading edge) to the back (trailing edge). 4. Camber : The curve of the airfoil from front to back. 5. Upper Surface: The top side of the airfoil, usually more curved. 6. Lower Surface : The bottom side of the airfoil, usually flatter. 7. Thickness : The distance between the top and bottom surfaces of the airfoil. 8. Angle of Attack (AoA) : The angle between the airfoil’s chord line and the wind direction.

5. Types of Airfoil S ymmetrical Ai rfoil : This has identical upper and lower surfaces such that the chord line and mean camber line are the same producing no lift at zero AOA. N on -S ymmetrical Ai rfoil : This has different upper and lower surfaces such that the chord line is placed above with large curvature. These have different chord line and camber line.
