How long are Vestas wind turbine blades?

How long are Vestas wind turbine blades?

The widely used GE 1.5-megawatt model, for example, consists of 116-ft blades atop a 212-ft tower for a total height of 328 feet. The blades sweep a vertical airspace of just under an acre. The 1.8-megawatt Vestas V90 from Denmark has 148-ft blades (sweeping more than 1.5 acres) on a 262-ft tower, totaling 410 feet.

Does the blade length affect wind turbines?

When it comes to wind turbines, bigger is definitely better. The bigger the radius of the rotor blades (or diameter of the “rotor disc”), the more wind the blades can use to turn into torque that drives the electrical generators in the hub. Larger and longer turbine blades mean greater aerodynamic efficiency.

How long is a wind turbine blade in meters?

For typical 1.5 MW turbines, you can expect a blade length between 35 and 45 meters, with a total rotor diameter between 75 and 100 meters.

How long is a v110 blade?

What is the longest wind turbine blade?

While LM Wind Power’s 107-metre blade is currently the longest in the world, longer blades are being designed. Siemens Gamesa Renewable Energy’s 14MW turbine will use 108-metre blades, and Danish turbine giant Vestas is due to unveil a new double-digit-MW turbine that could feature similarly sized blades.

How much does a single wind turbine blade cost?

Structural repair of a single wind blade can cost up to $30 000 and a new blade costs, on average, about $200 000.

How tall is a Vestas wind turbine?

With 112-meter towers and a tip height of 180 m, the wind turbines will be the tallest installed in the U.S., according to Vestas.
