Abstract

CONFIGURACION CIRCULAR DE PALETAS GIRATORIAS PARA ROTORES DE TURBINAS.LA CONFIGURACION ESTA FORMADA POR ASPAS (1) O PALETAS QUE TIENEN UN ANILLO DE REFUERZO INTEGRAL (15) CON UNA SUPERFICIE DE ATAQUE PLANA (17) Y UNA SUPERFICIE DE SALIDA PLANA (19). ESTA ULTIMA, SI ESTUVIERA EXTENDIDA, CRUZARIA EL PLANO RADIAL AXIAL QUE PASA POR EL CENTRO DE LA RAIZ (5) DEL ASPA, PARA FORMAR UN ANGULO IGUAL EN GRADOS A 360 DIVIDIDO ENTRE EL NUMERO DE ASPAS QUE FORMAN LA SERIE CIRCULAR.
