Abstract

Una estructura disco-álabes unitaria (10), que comprende: un disco (16) que incluye un reborde (16a); una fila de álabes (18) que se extiende en dirección radial hacia fuera desde dicho reborde en una estructura unitaria con éste para delimitar entre ellos unos correspondientes pasos de flujo (20); incluyendo el reborde (16a) del disco unos talones solidarios (40) que presentan una superficie de soldadura plana (42) que se complementa con una correspondiente raíz (34) del álabe y dicho reborde del disco incluye unos canales interiores (22) de vía de flujo ranurados que se extienden axialmente entre dichos álabes para deslindar dichos pasos (20) y Caracterizado por extenderse cada uno de dichos canales ranurados en círculo entre los álabes adyacentes y presentar entre ellos un contorno circularmente cóncavo.
