| 摘要 |
The invention relates to a rotor for a wind turbine, preferably for use as a vertical rotor, comprising two or more arms (1) which are arranged about the rotor axis (6) and on each of which a plurality of aerodynamically shaped airfoils (2) are arranged which run parallel to the rotor axis (6) and can be rotated about a longitudinal axis (5) of the airfoils (2) by incident flow and by centrifugal force, and which can be moved to a closed state by means of incident flow, in which state the airfoils (2) overlap each other. For damping the airfoils, each airfoil (2) comprises at least one permanent magnet (3, 4) both in the region of the longitudinal axis (5) and close to the end that is remote from the longitudinal axis (5), wherein in the closed state of the airfoils (2) a permanent magnet (3) on the longitudinal axis (5) of an airfoil is located opposite a permanent magnet (4) at the end of the an adjoining airfoil, wherein said two permanent magnets (3, 4) repel each other such that mutual contact of the adjoining airfoils is prevented. |
