Optimization of Windmill's Layered Composite Blades to reduce Aerodynamic Noise and Use in Construction of 'Green' Cities

摘要

One of the decisive factors in reducing the intensity of energy consumption is the use of energy-saving technologies in construction. The overall strategy for the development of energy efficient buildings starts with search of ways and means to reduce the energy-requirements - optimal use of natural energy resources. The trend of the new millennium is decentralization of power production. Accordingly, each building is regarded as an autonomous power plant. Limitations of using this source of renewable energy (RES), in urban development, such as wind power, are associated primarily with the noise that wind turbines make in the process of use.The article discusses the possibility of using multilayer composite materials in blades of perspective wind turbines and their comparison with peers from other materials.
