Abstract

La présente invention concerne une aube (9) d’une roue mobile tournante (8) d’une turbomachine, typiquement d’une roue mobile de turbine basse pression (7), comprenant :- une pale (10) à profil aérodynamique propre à s’étendre dans un flux d’air ; et - un talon (11), fixé sur une extrémité radiale externe de la pale (10), le talon (11) comprenant une plateforme (12) présentant une face interne (13) raccordée à la pale (10) et une face externe (14) portant au moins une léchette (15) ;l’aube (9) étant caractérisée en ce qu’elle comprend en outre une languette (19) monolithique avec la léchette (15) et s’étendant axialement depuis la léchette (15) à distance de la face externe (14) de la plateforme (12). Figure pour l’abrégé : Fig. 1The present invention relates to a blade (9) of a rotating impeller (8) of a turbomachine, typically a low pressure turbine impeller (7), comprising:- a blade (10) with an aerodynamic profile specific to spread out in an air stream; and - a heel (11), fixed to an outer radial end of the blade (10), the heel (11) comprising a platform (12) having an internal face (13) connected to the blade (10) and an external face (14) carrying at least one wiper (15);the blade (9) being characterized in that it further comprises a tongue (19) monolithic with the wiper (15) and extending axially from the wiper (15 ) away from the outer face (14) of the platform (12).
