Wind Turbine Blade Aerodynamics | Electrical Academia

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 rounded, while the other surface is relatively flat, which helps direct air flow. The blade on a wind
