A breakthrough in the wind: the blade will be lighter and more durable than 9.2.11, PtUchenye from Case Western Reserve University have developed a prototype blades for wind turbines, which is much easier and eight times stronger and more durable than those used today vetryakov. Usiliya blades to create a large wind turbines able to provide the energy a small town, is challenged by the weight of blades. The fact that the heavier lopastivetryaka, the greater the wind speed required for turning the rotor of the generator. This means that the wind turbine generates less energy and much of the wind acceleration is spent on heavy blades. To solve this problem by making the blades of light material, it is very difficult because the wind is bending the blades, they lose their best form, and again – reduced efficiency of the installation increases the cost of wind elektrichestva. Novaya blade made of polyurethane, reinforced with carbon nanotubes, significantly stiffer and lighter than any modern materials used in vetryakahNovaya blade made of polyurethane, reinforced with carbon nanotubes, significantly stiffer and lighter than any modern materials used in the windmill. With this new composite blades can produce any shape and is about eight times longer than the blades of epoxy reinforced with fiberglass. The results of mechanical tests of polyurethane with carbon nanotubes show its superiority over all the resins, which are currently used for the blades of wind turbines. At the same time carbon nanotubes per unit volume lighter than carbon fiber and aluminum, and also more than five times stronger than carbon fiber, and 60 times – alyuminiya. Opytnaya turbine with blades made of new material, showed good results: a rotor with a diameter of about 70 cm, it provides power to 400 watts and features a great performance than the wind turbines from the “traditional” materialov. Novy material is of great importance for the development of wind energy. Today it is being developed powerful wind turbines with 90 m blades that can generate about 15 MW of electricity. At relatively low cost of construction and operation, 300 of these wind turbines are in power plant and the use of new materials to make them more effective and more powerful. In addition, new blades can increase the power of small wind farms, which are becoming increasingly popular among owners of suburban nedvizhimosti.
