Abstract

ESTRUCTURA PERFECCIONADA, PARA MEJORAR EL COMPORTAMIENTO HIDRODINAMICO DE LAS HELICES DE BARCOS.COMPRENDE UNA PLURALIDAD DE ALABES DE GUIA (6) DISPUESTOS EN FORMA DE ENREJADO VERTICAL, A UNA DISTANCIA DE HASTA DOS DIAMETROS DE HELICE POR DELANTE DE LA MISMA, SITUADOS A BABOR Y ESTRIBOR, FIJADOS EN EL CASO (1) POR DELANTE DE LA HELICE (5), EN DONDE LOS ALABES (6) CURVADOS PRESENTAN EN SUS BORDES DE ENTRADA (8) UNA TANGENTE QUE ESTARA DIMENSIONADA PARA CONSEGUIR LA INCIDENCIA O ENTRADA SIN GOLPES DEL CORRESPONDIENTE FLUJO LOCAL DE LA CAPA LIMITE, Y POR TANTO, SUS BORDES DE SALIDA PRESENTAN UNA TANGENTE ORTOGONAL AL PLANO DE LA HELICE.
