Abstract
ALABES ESTACIONARIOS PERFECCIONADOS PARA UNA HILERA L-OC. COMPRENDEN UN ALA AERODINAMICA (40) QUE TIENE UN BORDE DE ATAQUE, UN BORDE DE SALIDA, UNA SUPERFICIE CONCAVA DE PRESION Y UNA SUPERFICIE CONVEXA DE SUCCION QUE SE EXTIENDEN ENTRE LOS BORDES DE ATAQUE Y SALIDA; UNA CORONA EXTERIOR (42) PARA CONECTAR EL EXTREMO PROXIMO DEL ALA AERODINAMICA AL CILINDRO INTERIOR (36) DE UNA TURBINA; UNA CORONA INTERIOR (44) CONECTADA AL EXTREMO DISTANTE DEL ALA AERODINAMICA; Y UNA JUNTA DE ESTANQUIDAD (46) ALOJADA EN LA CORONA INTERIOR Y APLICADA HERMETICAMENTE AL ROTOR (32) DE TURBINA. EL ANGULO DE ESCALONAMIENTO FORMADO POR LA CUERDA ENTRE DICHOS BORDES DE ATAQUE Y SALIDA Y UNA LINEA PARALELA AL EJE DEL ROTOR (32) OSCILA DESDE 42 EN EL EXTREMO DISTANTE DEL ALA AERODINAMICA (40) HASTA 52 EN SU EXTREMO PROXIMO. LA INVENCION ES APLICABLE A TURBINAS DE VAPOR.
