The wind pressure is the amount of force exerted by the wind per unit area of the blades and is given by: P = 1/2 (1 + c) * ρ * v 2. Where c is a constant and equals for long flat plates. The force of the wind against the windmill blade is based on the wind pressure multiplied by the area of the blade facing the oncoming flow.

The first blades ever installed offshore at Vindeby in 1991 were 17 meters long each. At the time this was an outstanding achievement and something we are still proud of. Today, our new B108 blade is the longest wind turbine blade ever produced. At 108 meters long, the blade is more than six times longer than the blades installed at Vindeby.
