How many meters long do wind turbine leaves grow?

The leaves of wind power plants measure between 34 and 88 meters long. The length of a wind turbine's blades 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, made at a factory in Denmark. Wind power is the process of using wind energy to operate wind turbines and then converting 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.

Based on the lever principle, the longer the lever arm, the lower the force required, so the long fan blades can also be blown away by small winds. The larger the surface area of ​​the fan blades, the greater the air resistance. If the fan blade is very wide and a strong wind blows, the fan blade will be blown over by the wind. Wind turbines are used to absorb wind energy rather than block it. The three-leaf blades and small width (strength) currently used can absorb wind energy to the maximum.um when they are rotated. If the blades are wider, it will affect the airflow through the rotation plane of the blades, which is not conducive to the absorption of wind energy when the wind speed v1 in front of the rotation plane of the rotor and the wind speed v2 behind the plane are equal. in a certain ratio, the yield is the highest, which is 59.3%. In comparison, the so-called material savings, costs and charging issues are not major problems. The key is to use this form to achieve higher absorption efficiency. If you are interested, you can search for Bates theory and Ye Su theory. Does the low-strength, few-blade wind rotor allow most of the airflow to escape? Low solidity wind turbines operate at high speeds and the linear speed of the blades is several times higher than the wind speed. They can sweep away most of theairflow that passes, leaving only a small part that does not pass through the blades. the passing airflow turns the blades and most of the wind energy is harnessed. Many experiments have been carried out at home and abroad to select the appropriate number of blades. Two, three and four blades are commonly used choices for wind turbines, with three blades being the most used. Of course, the choice of three blades also depends on the structural strength, manufacturing cost, noise, appearance and other reasons of the wind turbine. The multi-blade wind rotor has high strength and a relatively low wind energy utilization rate. But multi-blade wind rotors also have advantages. The output torque of a wind rotor of the same diameter is much higher than that of a wind rotor with small blades, and it has strong starting ability at low wind speed, so it is oftent the case. used in rural water pumping and grinding. In areas where the wind speed is stable, especially in areas with low wind speed, it is possible to achieve better wind energy utilization effects by using 4-8 blade wind turbines in operation. different uses.
