Steps/Methods
The blade diameter is not professional, it should be the sweep diameter. The mainstream blade shapes are 126/110/114, etc., and the corresponding blade sizes are 68m, 54m, and 56m; now the diameter of the largest wind turbine blade has exceeded 70 meters, which is equivalent to the wingspan of a Boeing aircraft.
When it comes to materials, it’s more complicated. Different parts of the blade have different materials. Generally speaking, three categories are used, carbon fiber and fiberglass as the outer surface, and balsa wood and foam as the core. material. The other thing is the binder. Carbon fiber is ideal because it has better strength and is lighter, but it is also a problem because it is too expensive. Balsa wood is balsa wood. As for foam, there are relatively many types, but they are generally hard foam. 3A products account for 90% of the share in this area. The main materials of wind turbine blades are fiberglass fabric and reinforced resin. Large-megawatt blade spar caps may adopt a carbon-glass hybrid design, and the shell web generally uses fiberglass fabric. In addition to LM, mainstream wind turbine blade manufacturers at home and abroad such as VESTAS, SIEMENS, GAMESA, etc. are all epoxy resin systems; LM relies on its own understanding of the interface bonding ability between resin and fiberglass fabric to use polyester resin, which has fast bonding speed, no need for heating in the post-curing process, and high mold turnover efficiency.
How many meters is a wind turbine blade?
The blades of wind turbines are between 34 meters and 88 meters long. The blade length of a wind turbine will vary 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 tens of meters. Wind power of 1.5 megawatts (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 blade length is between 48 and 59 meters, and the corresponding hub height is between 48 and 59 meters. The height of a 3-MW wind turbine is 80 to 100 meters, and the blade length is between 44 and 59 meters. The corresponding hub height is 80 to 110 meters. The blade length of the largest known wind turbine in the world has reached 88 meters, made in a factory in Denmark. Wind power is the process of using wind power to drive wind turbines and then converting the wind energy into electricity. This clean energy technology is widely used around the world because it helps reduce dependence on fossil fuels and reduces greenhouse gases. emission.
Its length ranges from 40 meters to 90 meters.
Generally speaking, the length of wind turbine fan blades is between 40 meters and 90 meters. For example, the blade length of a 1.5MW wind turbine is about 40 to 55 meters, the blade length of a 2 to 3MW wind turbine is about 55 to 65 meters, and the blade length of a 5MW and above wind turbine is 65 to 90 meters. meters.
Wind turbine fan blades are made of carbon fiber, glass fiber and other materials, which are lightweight and high in strength. ThatThe working principle is to use wind power to turn a generator and convert wind energy into electrical energy. Wind power is not only clean and environmentally friendly, but also reduces dependence on traditional energy sources, which is of great significance to sustainable development.
