CURVED CROSS-SECTION WIND TURBINE TOWER AND WIND TURBINE COMPRISING SAID TOWER

摘要

The tower (15) comprises: a wall (11) having an orifice (12) for accessing the interior of the tower (15), and an outer surface defined by generatrices; and a reinforcement frame (13) joined to the tower (15) in the orifice (12) zone, and comprising least two parts (14) joined therebetween. Each part (14) has a midplane (20) that is parallel to at least one generatrix, the mid-planes (20) of at least one pair of adjacent parts (14) forming an angle other than 180° therebetween. It enables the obtention of a frame (13) more conformed to the curvature of the tower (15), combining savings in the material of said frame (13), greater optimisation of the resistance of the tower (15) and reduced stress concentration.
