How do wind turbines work?
The huge rotor blades on the front of a wind turbine are the "turbine" part. The blades have a special curved shape, similar to the airfoil wings on a plane. When wind blows past a plane''s wings, it moves them upward with a force we call lift; when it blows past a turbine''s blades, it spins them around instead.

Explore a Wind Turbine
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
The Science Behind Wind Blades and How They Work
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases.
How Wind Turbine Blades Are Manufactured?

Wind Turbine Blade Aerodynamics
The wind turbine blade on a wind generator is an airfoil, as is the wing on an airplane. By orienting an airplane wing so that it deflects air downward, a pressure difference is created that causes lift. On an airplane wing, the top surface is
Airfoils, Where the Turbine Meets the Wind
A design improvement in the blade root coincides with improved turbine performance in the face of soiling and roughness. These findings made it clear that new, customized airfoils were needed for each section along the wind turbine blade. All in the (Airfoil) Family. The result of this research was the first "airfoil family" for wind turbines.
