horizontal axes turbine, vertical axes turbine, rotor blade geometry, aerodynamic shape


The consumers’ energy needs and the variable wind potential have led the wind turbine producers to construct turbines that could efficiently operate in an as wide as possible range of wind speed power and domain. The rotor blade geometry is one of the factors that directly affect the turbine efficiency. The performance of the wind turbine depends upon blade and shape size but also upon their number. One of the main objectives in the design of the rotor blades lies in having an aerodynamic shape with high lift capacity and small drag force.
