Abstract
UN VENTILADOR DE MOVIMIENTO AXIAL (10, 20) QUE CONSTA DE UN CUBO (12) QUE PUEDE GIRAR ALREDEDOR DE UN EJE; Y UNA PLURALIDAD DE PALETAS (16, 17, 18, 19) QUE SE EXTIENDEN DESDE EL CUBO, CONSTANDO CADA UNA DE LAS PALETAS DE UNA PORCION RAIZ ADYACENTE AL CUBO Y QUE TERMINAN EN UNA PORCION DE PUNTA, ESTANDO LAS PORCIONES RAIZ DE LAS PALETAS SEPARADAS DE MANERA APROXIMADAMENTE UNIFORME ALREDEDOR DEL CUBO; EN DONDE CADA UNA DE LAS PALETAS PRESENTA UNA CURVATURA DESDE LA PORCION RAIZ DE LA PALETA A LA PORCION DE PUNTA DE LA PALETA, ESTANDO LA CURVATURA EN UN PLANO QUE ES PERPENDICULAR AL EJE SOBRE EL QUE GIRA EL VENTILADOR; Y EN DONDE LA CURVATURA DIFIERE ENTRE AL MENOS DOS DE LAS PALETAS DE MODO QUE LA DISTANCIA ENTRE LAS PORCIONES DE PUNTA DE AL MENOS DOS JUEGOS DE PALETAS ADYACENTES ES DESIGUAL. LA INVENCION PRESENTA POR TANTO LA VENTAJA DE TENER UNA SEPARACION DESIGUAL ENTRE LAS PALETAS CERCA DE LA PUNTA AL TIEMPO QUE SE MANTIENE UNA GRAN SOLIDEZ CERCA DEL CUBO, DONDE LA SEPARACION ENTRE LAS PALETAS ES UNIFORME.
