Abstract

Plateforme inter-aubes et disque de support Un aspect de l’invention concerne une plateforme inter-aubes (1) et un disque de support (2) d’un rotor de soufflante (A) comprenant un axe de rotation (X), comprenant chacun respectivement un pied d’attache (124) et un pied de fixation (224) situé plus proche du milieu axial qu’une extrémité aval (10b, 22b) et qu’une extrémité amont (10a, 22a) de respectivement la plateforme inter-aubes et du disque de support (2). Le pied d’attache (124) et le pied de fixation (224) comprennent chacun une partie en forme de rail glissière (1240, 2240) formant ensemble une liaison rail glissière mâle ou femelle pour permettre de retenir radialement la plateforme inter-aubes (1).
