This fan blade is approximately 70 meters long.
According to the official wind turbine website, the main blade shapes of wind turbines are 126, 110, 114, etc., and the corresponding blade sizes are now 68m, 54m, 56m. the largest wind turbine blade diameter exceeded 70 meters, the equivalent of the wingspan of a Boeing plane.
This fan blade uses wind energy to produce electricity. The design of the wind turbine blade directly affects the conversion efficiency of wind energy and directly affects its annual energy output. use.
Its length varies 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 1.5 MW wind turbine is about 40 to 55 meters, the blade length of a 2 to 3 MW wind turbine is about 55 to65 meters and the length of the blades of a wind turbine of 5 MW and more is between 65 and 65 meters. and 90 meters.
Wind turbine fan blades are made of carbon fiber, glass fiber and other materials, light in weight and high in strength. Its working principle is to use wind energy to turn a generator and convert wind energy into electrical energy. Wind energy is not only clean and environmentally friendly, but also reduces dependence on traditional energy sources, which is of great importance for sustainable development.
