Wind Turbine Blade Technology: Designing for Efficiency

Wind turbine blades are the primary components responsible for capturing wind energy and converting it into mechanical power, which is then transformed into electrical energy through a generator. The fundamental goal of blade design is to extract as much kinetic energy from the wind as possible while minimizing losses due to friction and turbulence.

How Do Wind Turbines Work? | Department of Energy

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.
