The greater extent of Cearà State (about 90% of its territory) is supplied by winds of the order of 3.5 to 5m / s. On the same extent of territory lie the settlements of farmers (responsible for producing most of the food consumed in our territory) are located in these same regions and possess not support the industries in developing specific equipment to meet the demand energy of these, since the application of wind turbines for power generation is not appropriate. We could use for this purpose, small generators that mostly have curves also not appropriate to these sites. This paper presents a model for designing blades for wind turbines with a view to use in areas characterized as low wind using camber profile. A mathematical model was developed for the design and modeling of the blades of a rotor starting data of wind speeds characteristic of regions of settlements of farmers, potency and specific characteristics required for the installation site generating dimensional parameters enabling the manufacture of rotor blades . The validation model used academic software for comparative data generated by the model. As a way to refine the model, we propose preparation of prototype scale using the methodology presented dimensional analysis coefficients Pi-terms for this purpose.
