Abstract

UNA HELICE MARINA DE PASO VARIABLE DE DOS O MAS PALAS HELICOIDALES MONTADAS SOBRE UN CUBO DE FORMA QUE CADA PALA PUEDE GIRAR LIBREMENTE ALREDEDOR DE UNOS EJES RADIALES. SE BASA EN QUE LOS EFECTOS CENTRIFUGOS QUE ACTUAN SOBRE LAS PALAS DEBEN SER RELACIONADOS ESPECIFICAMENTE CON LAS FUERZAS HIDRODINAMICAS QUE ACTUAN SOBRE LAS PALAS. LA DESVIACION DE LAS PALAS SOBRE LOS EJES DE GIRO Y LA FORMA DE LOS BORDES DE SALIDA EN RELACION CON LOS EJES DE GIRO SON FACTORES CRITICOS. U
