Abstract

SE HA MONTADO UN DISPOSITIVO QUE PROVOCA TURBULENCIAS EN EL BORDE DE ATAQUE DE UNA PALA (4) PARA AMORTIGUAR O IMPEDIR TOTALMENTE LAS VIBRACIONES DE DESENGANCHE DE PALAS DE TURBINA EOLICA. ESTE DISPOSITIVO PUEDE ESTAR FORMADO COMO UNA BANDA (3) CON UNA SECCION TRIANGULAR EQUILATERAL Y PUEDE COLOCARSE PRACTICAMENTE A NIVEL DEL PUNTO DE PARADA. LA LONGITUD DE ESTA BANDA PUEDE SER DEL ORDEN DEL 2,5% DE LA LONGITUD DE LA PALA Y SE PUEDE MONTAR A PARTIR DE UN RADIO DEL 15% DESDE EL EXTREMO DE LA PALA Y HACIA EL CENTRO DE LA MISMA.
