Abstract
The studies carried out in the field of wind turbines have led to a structural design of horizontal axis wind turbines composed of a set of three blades of composite material. The blades are subjected to dynamic loads which assume variable intensities over time. These dynamic influences, for a long time, by the difficulty of numerical reproduction, are estimated by a static load. Thus, the parameters of resistance were evaluated in order to improve the numerical modeling, since the manufacturer does not provide all the data characteristic of the blade. However, in the field of evaluation of the strength of the structural element, the numerical-experimental analysis was proposed here under a static approach on a blade of a small Verne 555 wind turbine. The characteristics of the blade were not provided by the manufacturer as being industrial property. Thus, the blade was subjected to reading metrology to obtain the external geometry, as well as the composite materials used in its manufacture were estimated, using physical parameters based on the literature. The results extracted in both models were compared based on the observation of the deflection at four points of the blade and were satisfactory, since this is still a preliminary investigation.
