Abstract

UNA REJILLA 2,3 DE PALETA PARA MAQUINA DE CORRIENTE AXIAL MUESTRA PALETAS 4,5, QUE DISPONEN DE FORMA DE FLECHA AXIAL, EN LA ZONA DE LAS PUNTAS 17,13 DE LA HOJA DE PALETA Y DEL PIE DE PALETA DE FORMA POSITIVA. LOS BORDE 11 DELANTEROS DE LA PALETA EN LA ZONA DE LA PUNTA 17 DE LA HOJA DE PALETA Y DEL PIE 13 DE ESTA PALETA MUESTRAN UN TRAMO QUE DISCURRE EN LINEA RECTA Y EN CONEXION CON EL, CON RESPECTO A LA ZONA MEDIA DE LA PALETA, UN TRAMO QUE DISCURRE DE FORMA DOBLADA. LA DISPOSICION DE FLECHA EN LA DIRECCION Z AXIAL PUEDE SER SOPORTADO POR MEDIO DE UNA CURVATURA DE LAS PALETAS 4,5 EN LA DIRECCION ..OMEGA.. PERIMETRICA. POR MOTIVOS DEL DESARROLLO EN FORMA DE FLECHA, EN LINEA RECTA, DE LOS BORDES 11 DELANTEROS DE LA PALETA EN LA ZONA DE LA PUNTA 7 DE HOJA DE PALETA Y DEL PIE 13 DE LA PALETA RESULTA UN INFLUJO DE LA CORRIENTE SECUNDARIA, DE FORMA QUE SE PERMITE UNA MEJORA DEL RENDIMIENTO DE ETAPA TANTO EN LA ZONA DE PALETA, COMO TAMBIEN EN LA REJILLA 2 O 3 DE LA PALETA DE CONDUCCION.
