The geometric characteristics of the blade profile are obtained by&amp;nbsp;determining the distribution of the chord and twist angle for each blade section. In order to maximize&amp;nbsp;the wind energy production, implying a maximum lift-to-drag ratio for each wind speed, this&amp;nbsp;distribution should be optimized. This paper presents a methodology to numerically determine the&amp;nbsp;change in the twist angle by introducing a range of pitch angles for the maximum power coefficient&amp;nbsp;case. The obtained pitch values were&amp;nbsp; distributed from the root to the tip of blade. The results prove&amp;nbsp;that the power coefficient increases for wind speeds greater than the rated point, which&amp;nbsp; improves the&amp;nbsp;yearly production of energy by 5% compared to the reference case</style></abstract><issue><style face="normal" font="default" size="100%">01</style></issue></record></records></xml>
