Abstract

LA HOJA ROTORA CONOCIDA DE LAS MAQUINAS DE FLUJO AXIAL HA SIDO MEJORADA. LA MEJORA CONSISTE EN LA NUEVA CONFIGURACION DE LA RESPECTIVAS HOJAS DEL ROTOR. EL FILO PRINCIPAL DE LA PARTE SUPERIOR DE CADA HOJA SE INCLINA HACIA ADELANTE DEL LADO CONTRACORRIENTE, Y TAMBIEN AVANZA EN LA DIRECCION DE ROTACION. EN LA PORCION DE LA PARTE SUPERIOR, ENTRE LA SUPERFICIE DE LA PARTE SUPERIOR Y LA SECCION TRANSVERSAL DESPLAZADA DE LA SUPERFICIE DE LA PARTE SUPERIOR EN DIRECCION A LA PORCION CENTRAL POR 1/2 DE LA LONGITUD DE LA CUERDA, LA CONFIGURACION DEL FILO PRINCIPAL EN LA PORCION DE LA PARTE SUPERIOR ES TAL, QUE EL ANGULO S DE LA DIRECCION DE INCLINACION DEL FILO PRINCIPAL DE LA PORCION DE LA PARTE SUPERIOR EN LA DIRECCION DE ROTACION Y LA CANTIDAD DE INCLINACION EFECTIVA (THETA) SUB S EN LA DIRECCION DEL FILO PRINCIPAL DE LA PORCION DE LA PARTE SUPERIOR INCLINANDO HACIA ADELANTE LA CARA CONTRACORRIENTE EN UNA REGION PARTICULAR EN UN DIAGRAMA DE S EN CONTRA (THETA) SUB S EFF DELIMITADA POR 4 PTOS. ESPECIFICAS A, B, C, Y D DETERMINADAS MEDIANTE EXPERIMENTOS.
