The Study On Vane Design Of Wind Turbine

In order to meet increasing need of energy and the press of environment protection, Inthe world many country increase the develop degree of new energy. Today the clean,pollute-free, green and renewable energy has become the focus of world's energydevelopment. Wind energy is the most representational energy in clean reproducible energy,It has important signification of the environment protection and ecosystems balance, it canreduce the depend on the conventional source of energy and improve the energy structure.The keystone of the development makes use of the wind power machine is to convert thewind energy into the electric power. Horizontal-axis wind turbine is also the most form ofmany wind energy use forms, the blade of wind turbine is also the important part. Alongwith the development of computer technology and CFD, the design and research work ofwind turbine also keep deeply developing, It also appears many new ways of vane design,in simultaneously master the basic theory of wind turbine, we must develop our own wayof vane design.The blade of wind turbine absorbing the wind energy and converting into machineenergy, then drive the generator and gain the electric energy. For this important component,its research is the threshold of the research of wind turbine, we must attach importance tothe basic research work. After recommending the trend of wind power and the technologyof wind energy, Use the basic concept of aerofoil and wind turbine vane exterior parameterto design the vane. And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.
