The design of wind turbine blades is a delicate balance between aerodynamic efficiency and structural integrity. Blades are engineered with specific airfoil profiles, the shape of the blade cross-section. These profiles are carefully crafted to minimize drag, maximize lift, and ensure optimal energy capture from the wind.

The ratio between the blade speed and the wind speed is called tip-speed ratio. High efficiency 3-blade-turbines have tip speed/wind speed ratios of 6 to 7.
