Abstract

L'invention concerne une soufflante comprenant : - un disque (10) de soufflante (1), - une plateforme (20) inter-aubes (2) comprenant une base (22) et une patte (26) radiale, un deuxième orifice (28) étant formé dans la patte (26) de la plateforme (20), et - un verrou (30) présentant un bord amont (32) configuré pour venir en appui contre la face amont (12) du disque (10) et un bord aval (36) configuré pour prendre appui contre la patte (26) de la plateforme (20), l'un parmi le bord aval (36) et la chape (14) du disque (10) de soufflante (1) comprenant un pion (37), l'autre comprenant un premier orifice (16), le pion (37) étant configuré pour pénétrer dans le premier orifice (16) et dans le deuxième orifice (28) de sorte à bloquer la plateforme (20) par rapport au disque (10) de soufflante (1).The invention relates to a blower comprising: - a blower disc (10) (1), - an inter-blade platform (20) (2) comprising a base (22) and a radial tab (26), a second orifice ( 28) being formed in the tab (26) of the platform (20), and - a latch (30) having an upstream edge (32) configured to bear against the upstream face (12) of the disc (10) and a downstream edge (36) configured to bear against the tab (26) of the platform (20), one of the downstream edge (36) and the yoke (14) of the fan disc (10) (1) comprising a pin (37), the other comprising a first hole (16), the pin (37) being configured to enter the first hole (16) and the second hole (28) so as to block the platform (20) by relative to the fan disc (10) (1).
