Future Priorities for Wildlife & Wind Energy

The blades of a wind turbine are affected by four forces: drag, lift, centrifugal, and gravitational forces. Drag Force on Wind Turbine Drag forces are caused by the air molecules that hit the surface of the blade facing the wind. A major component of the drag force acts in the direction that is parallel to…

Wind turbines work on a simple principle. The wind hits the rotor blades. The combination of wind speed and blade rotation results in a pressure distribution on the rotor blades. The pressure distribution causes a turning moment (torque). The turning moment rotates the shaft. The shaft is coupled to a generator that produces electrical power…
