Abstract

Plataforma (150) para una rueda de álabes de turbomáquina, que comprende un tambor (130) y unos álabes (120) de tipo de fijación por cabeza de martillo, que comprende, al menos, dos aberturas (151) separadas en dirección circunferencial y aptas para recibir, cada una, el pie (122) de un álabe (120), por lo que constituye una plataforma de múltiples álabes a modo de una pieza separada de los álabes (120), que cubre un sector angular, y caracterizada por que comprende además dos refuerzos (153) que comprenden unas caras de apoyo laterales (153a) que constituyen unos soportes axiales, aptos para cooperar con el tambor (130) a fin de retener axialmente, por sí mismos, la plataforma (150) sobre el tambor (130) y reducir las recirculaciones de aire.
