Wind turbine fan blades are made of various materials, such as wood, metal, engineering plastics, fiberglass, etc. Among them, micro wind turbine blades are generally made by hand from wood, using cold stamping or metal injection molding processes; The blades of small wind turbines are usually made by hand from metal or fiberglass, among which fiberglass blades are the most popular and practical blades. Large wind turbine blades are usually made by hand from fiberglass.
Blades are the most fundamental and critical components of wind turbines. Their good design, reliable quality and superior performance are the decisive factors to ensure the normal and stable operation of the unit.
The leaves of wind power plants measure between 34 and 88 meters long. Lhe length of the blades of a wind turbine varies depending on the size and model of the wind turbine. Small wind turbines have blade lengths of several meters, while large commercial wind turbines can have blade lengths of several tens of meters. MW) For generators, the blade length is between 34 and 45 meters, and the corresponding tower height (hub height) is 65 to 100 meters. For a 2 MW wind turbine, the length of the blades is between 48 and 59 meters, and the corresponding height. the height of the hub is between 48 and 59 meters. The height of a 3 MW wind turbine is between 80 and 100 meters and the length of the blades is between 44 and 59 meters. The corresponding hub height is between 80 and 110 meters. The world's largest known wind turbine reached 88 meters, manufactured in a factory in Denmark. Wind power is the process of using wind energy toto operate wind turbines, then convert the wind energy into electricity. This clean energy technology is widely used around the world as it helps reduce dependence on fossil fuels and reduces greenhouse gas emissions.
