Abstract

Álabe (10) para una turbomáquina, que comprende: - al menos una cavidad (28) interior definida por una pared (30) interior que tiene una pluralidad de orificios (40) de impacto, y - una pared (14) exterior que rodea la pared (30) interior formando un paso (36) entre las mismas para que un fluido de refrigeración pase a través de los orificios (40) de impacto desde la cavidad (28) interior hacia el paso (36), en el que la pared (14) exterior comprende una pluralidad de aberturas (24) para la salida del fluido de refrigeración, caracterizado porque, la pared (14) exterior está dividida en una pluralidad de partes (15, 17) desconectadas entre sí mediante una abertura (24), abertura que se extiende en una dirección radial con respecto a un eje de rotación de un rotor de la turbomáquina entre una primera y una segunda parte (15, 17), permitiendo la expansión térmica independiente de dichas partes (15, 17).
