107 meters.
The largest wind blade is 107 meters long, with a rotor diameter of 220 meters, a hub height of 135 meters and a maximum blade tip height of 260 meters. of the Statue of Liberty in New York, from the ground to the torch, three times the height of the tip.
The larger wind turbine will be able to improve the efficiency of wind energy harvesting, reduce the cost of wind power generation, and provide better solutions for the future development of clean energy.
See that China has the largest SL5000 wind turbine in the world. I'm very proud and would like to ask how long one of his fan blades is. It rotates once during operation
1 Common blade shapes of wind turbines are 126/110/114, etc., and. the corresponding blade sizes are 68 m and 54 m, 56 m; the largest diameter of the wind turbine blade now exceedsbut 70 meters, equivalent to the wingspan of a Boeing plane.
2. Blades are an industry with greater certainty, greater market capacity and a clear profit model among wind power components. As the tense supply and demand situation eases, the wind power blade industry will also undergo a transformation, from a melee between a group of heroes to a struggle for hegemony between some powerful actors. redesign and integration.
3. As the scale of the wind turbine blade market expands, costs and sales prices will decrease. However, companies with scale, technology and cost advantages will see their costs fall faster than their sales prices. their profits will exceed the average level. The future landscape of industrial competition requires manufacturers to expand scale, reduce costs and maintain certain advantages.technological developments.
The height of the fan is generally linked to the length of the blades and the customer's choice. Generally, the blade diameter of 5000 kW fan is 100 meters or more, and the height is greater. more than 80 meters away.
A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanical work causes the rotor to rotate and ultimately produces alternating current. Wind turbines generally consist of components such as a wind wheel, a generator (including devices), a steering (tail), a tower, a speed-limiting safety mechanism, and an energy storage device.
The operating principle of a wind turbine is relatively simple. The wind wheel rotates under the influence of the wind. It converts the kinetic energy of the wind into the mechanical energy of the wind wheel shaft. wind wheel shaft drive for progenerate electricity.
Generally speaking, wind energy is also solar energy, so we can also say that a wind turbine is a thermal energy generator that uses the sun as a heat source and the atmosphere as a working fluid.
For many centuries, wind turbines, like hydraulic machines, have played an important role in the development of productivity as a source of energy to replace human and animal energy. The widespread application of electromechanical power in modern times and the discovery of oil deposits in the Middle East in the 1950s slowed the development of wind turbines.
In the early 1970s, due to the “oil crisis”, energy shortages appeared. People have become aware of the instability and limits of conventional fossil energy supplies, so the search for clean energy et renewables has become a key issue in the modern economy. world. an important subject.
Wind power, as a renewable and non-polluting natural energy source, has once again attracted people's attention.
