Novelty: wind generator’s blades. Technical features: the blades 2 in question are characterised in that they are furnished with semi-spherical cavities 3 placed in series and alternatively lengthwise the blades surface. Due to these semi-spherical cavities said blades are in position to actively manage their released air mass what leads to their smoother and more stable rotation and, thereby, to a more qualitative, reliable, economical and noiseless operation of the wind generator; faster rotation of blades (more revs per minute) and more power production can be obtained, to a great extent, by the expansion of the difference of wind pressure exerted on the two sides of the blades. |
