Abstract
Un dispositivo de fijacion para alabes para turbinas de gas del tipo utilizado para la primera etapa de la turbina (con suministro de aire de enfriamientodesde la raíz hacia la parte superior),comprende una pluralidad de placas (13), cada una de lascuales está provista de por lo menos una proyeccion de forma enU(19), que puede calzar con una correspondiente acanaladura (39) de forma en U presente en la superficie del disco (15) de la primera etapa de la turbina, demodo que cada una de las placas (13) esté interpuesta entre dos alabes (11) adyacentes, a fin de fijarlos axialmente. El objetivo del invento es también undispositivo de fijacion para alabes para turbinas de gas, del tipo utilizado para la segunda etapa de la turbina (alabes no enfriados) que comprende unapluralidad de placas (23, 43), cada una de las cuales está interpuesta entre la porcion extrema (22) del pie (27) de un correspondiente alabe (21) y el disco(24) de la turbina, y cada una de las cuales esta provista de extremos (25, 26, 45, 46) para fijar el alabe (21) axialmente.
