<p>A continuously manufactured profile having maximum curvature and chord with a constant torsion and a constant section, can be reshaped to obtain the required curvature, the required chord and the required correction on the position angle by modification of a relatively small part of the tail of the profile. This discovery enables mass production and stocking of profile to be mounted as blades on axial fans and windturbines of a wide capacity range.</p> |
