Abstract
Since the 70's the use of wind energy has been growing up, as well as researches about it too. However, research has now been larger in wind power generation with small turbines. Tends in view this need, this research proposes the manufacture of the turbine blade with a different airfoil than the one suggested by producer. After simulations in the Qblade, with some airfoils, were found better results in NACA 63(2)-615. After the simulations, the blade was manufactured using the Resin Transfer Moulding (RTM), but before fabrication of the blade, one model had to be manufactured manually with wood. Therewith, the mold could be made. The mold was made in two parts and in the same way, the blades. A part of each blade was laminated on each part of the mold and after the curing period, another piece of glass fiber was placed between the two parts with the resin and the catalyst to join them. After lamination, the fittings were made for the fit in the turbine and the reduction in the laterals for efficiency improvement.
