Abstract

ALABE DE MONTAJE LIBRE PARA UTILIZACION EN UNA TURBINA DE BAJA PRESION. SE HA DISEÑADO UN ALABE DE TURBINA PARA EVITAR TENER QUE MECANIZAR UNA PARTE DEL ULTIMO ALABE ENSAMBLADO EN UNA FILA PARA LOGRAR SU AJUSTE. LA SITUACION DEL CENTRO DE GIRO DE LA RAIZ FUE ELEGIDA CUIDADOSAMENTE PARA QUE ESTUVIERA EN LA PROXIMIDAD VERTICAL AL BORDE DE ATAQUE DE LA PLATAFORMA.
