Abstract

Una envoltura de un álabe de estátor incluye un pasaje lateral de succión (73n), un pasaje lateral de presión (73p), y una pluralidad de pasajes del extremo posterior (76). La pluralidad de pasajes del extremo posterior (76) están dispuestos para alinearse en una dirección lateral (Dc) entre el pasaje lateral de succión (73n) que se extiende a lo largo de una superficie del extremo lateral de succión (63n) y el pasaje lateral de presión (73p) que se extiende a lo largo de una superficie del extremo lateral de presión (63p), y se abren en una superficie del extremo posterior (62b). Un primer pasaje lateral de succión del extremo posterior (76n1) más cercano al pasaje lateral de succión (73n) entre la pluralidad de pasajes del extremo posterior (76) se extiende gradualmente más cerca del pasaje lateral de succión (73n) hacia una cara corriente abajo. Un primer pasaje lateral de presión del extremo posterior(76p1) más cercano al pasaje lateral de presión (73p) entre la pluralidad de pasajes del extremo posterior (76) se extiende gradualmente más cerca del pasaje lateral de presión (73p) hacia la cara corriente abajo.
