Abstract
Grupo (10) de álabes directores para una turbomáquina, en particular para un turborreactor, con al menos dos álabes (14), que están unidos entre sí mediante al menos una plataforma común (12, 16) para delimitar radialmente un canal de flujo de la turbomáquina, en donde cada álabe (14) presenta una hoja (17) de álabe con un lado (18) de aspiración y un lado (20) de presión, que están unidos entre sí en un borde delantero (22) y en un borde trasero (24), en donde los al menos dos álabes (14) presentan espesores de pared del borde trasero diferentes al menos en una zona de extensión longitudinal radial correspondiente, caracterizado por que los al menos dos álabes (14) están configurados en esencia idénticos en una zona axial de al menos un 50 % partiendo del borde delantero.
