Vertical axis micro wind turbines mainly refer to vertical axis wind turbines with a power of less than 100W. The size of this type of wind turbine generally does not exceed 50cm x 50cm, and the rated speed of the wind is between 10 m/s and 20 m/s. Compared with traditional wind turbines, this type of wind turbine has the advantages of small size, easy installation and strong portability.

Steps/methods
The blade diameter is not professional, it should be the sweeping diameter. Common 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 theame have different materials. Generally speaking, three categories are used, carbon fiber and fiberglass as the exterior surface, and balsa wood and foam as the surface. base material. The other problem is that carbon fiber is ideal because it is stronger and lighter, but it is also problematic because it is too expensive. Balsa wood is balsa wood. As for foam, there are relatively many types, but generally hard foam products account for 90% of the share in this field. The main materials of wind turbine blades are fiberglass fabric and reinforced resin. Large megawatt blade spar caps can adopt a carbon-glass hybrid design, and the hull cloth generally uses fiberglass cloth. In addition to LM, the main manufacturers of wind turbine blades at home. and abroad such as VESTAS, SIEMENS, GAMESA, etc. are tou 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. the post-curing process and high efficiency of mold renewal.
The size of the Nomuhong wind turbine in Haixi Prefecture, Qinghai Province is a 1,500 kW wind turbine with a diameter of 77 meters and a tower height of 65 meters. According to the request for relevant public information, the Nomuhong wind turbine in Haixi Prefecture, Qinghai Province, is the main generator in China. The size of the wind turbine is 77 meters in diameter and the tower is 65 meters high. Energy is transformed into mechanical work, and the mechanical work drives the rotor. The rotor spins and ultimately produces alternating current.
