A methodology is developed to estimate the chord distribution airfoil and blade twist along the radius of the blade by using axial and angular moment conservation equations, blade element theory and optimization processes. This methodology takes into account the concept related with getting wind power for different chord blade values and selecting one that facilitates to get the maximum value for wind power. Simulation of power generation output was carried out by using a wind-speed probability distribution function (PDF) obtained from data collected at the Guajira region of Colombia.
