Abstract

SE PRESENTA UNA HELICE DE VENTILADOR TRANSVERSAL QUE TIENE PALAS QUE SE EXTIENDEN LONGITUDINALMENTE PARALELAS AL EJE ROTACIONAL DE LA HELICE. CADA PALA TIENE UNA SECCION DE CORTE DEL PERFIL AERODINAMICO, DEFINIDA POR UNA LINEA DE CUERDA (CH) Y UNA LINEA DE ALABEO (CA), Y ESTA POSICIONADA EN LA HELICE EN UN ANGULO DE DISPOSICION (R). EL BORDE MAS EXTERIOR (EO) DE CADA PALA SE SITUA A UNA DISTANCIA (RMAX) DEL EJE ROTACIONAL (AR, AR''). LA SEPARACION ANGULAR ((SIGMA)) ENTRE LAS PALAS EN EL VENTILADOR ES UNIFORME. ENTRE LAS PALAS DE LA HELICE, LOS VALORES DE AL MENOS UNO DE LOS PARAMETROS DISTANCIA DESDE EL BORDE MAS EXTERIOR AL EJE ROTACIONAL (RMAX), LONGITUD DE LA LINEA DE CUERDA (CH), DESVIACION MAXIMA DE LA LINEA DE ALABEO DE LA LINEA DE CUERDA (DMAX) Y ANGULO DE ATAQUE DE LAS PALAS VARIA ALEATORIAMENTE DE LOS VALORES DE REFERENCIA DE ESTOS PARAMETROS. LAS VARIACIONES PARAMETRICAS ALEATORIAS REDUCEN EL RUIDO TONAL DE LA PALA PRODUCIDO POR UN VENTILADOR QUE TIENE DICHA HELICE COMPARADO CON UNVENTILADOR QUE TENGA UNA HELICE CON PARAMETROS DE PALA UNIFORMES.
