ROTOR FOR DARRIEUS-TYPE WIND TURBINE OF LOW POWER WITH VERTICAL AXLE AND SYSTEM FOR REDUCING VIBRATIONS AND LOAD, MEANT FOR URBAN IMPLEMENTATION

The invention relates to a rotor for Darrieus-type wind turbine of low power with vertical axle, with system of reducing vibrations and load, meant for urban implementation. According to the invention, the rotor comprises three blades () placed under an angle of 120°, with aerodynamic profile, with adjustable elastic elements, where the elastic elements for clamping the ends of the blades () onto the axle provide the blade deformation according to an optimal shape, depending on the rotation speed, and at the ends of the blades () meant for their clamping onto an end disk (), the clamping allows the self-adjustment of the position by means of some articulations () and thus the reduction of the strains within the blades (). Invenţia se referă la un rotor pentru turbină eoliană, de mică putere, destinată implementării urbane, cu ax vertical, de tip Darrieus, cu sistem de reducere a vibraţiilor şi a încărcărilor. Rotorul conform invenţiei are în componenţă trei pale () amplasate la 120°, cu profil aerodinamic, cu elemente elastice ajustabile, la care elementele elastice de prindere pe ax a capetelor palelor () asigură deformarea palei după o formă optimă, în funcţie de viteza de rotaţie, iar la capetele de prindere ale palelor () de un disc () de capăt, prinderea permite autoajustarea poziţiei prin intermediul unor articulaţii () şi, astfel, reducerea tensiunilor din pale ().
