Title (EN) COMPONENT FOR A TURBOMACHINE
(FR) COMPOSANT DE TURBOMACHINE
Abstract:
(EN) A component (300, 400) for use in a turbomachine is provided. The component (300, 400) comprises a platform (310, 410) having a leading end (312, 412) longitudinally spaced apart from a trailing end (312, 412), an aerofoil portion (320, 420) extending from the platform (310, 410), the aerofoil portion (320, 420) having a leading edge (322, 422) and a trailing edge (314, 414). The platform (310, 410) further comprises a leading end region (315, 415) between the leading end (312, 412) of the platform (310, 410) and the leading edge (322, 422) of the aerofoil portion (320, 420), and a depression (330, 430) which extends into the platform (310, 410), and is located in the leading end region (315, 415).
(FR) L'invention concerne un composant (300, 400) qui est utilisé dans un turbomachine. Le composant (300, 400) comprend une plateforme (310, 410) ayant une extrémité avant (312, 412) espacée longitudinalement d'une extrémité arrière (312, 412), une partie de profil aérodynamique (320, 420) s'étendant à partir de la plateforme (310, 410), la partie de profil aérodynamique (320, 420) ayant un bord d'attaque (322, 422) et un bord de fuite (314, 414). La plateforme (310, 410) comprend en outre une région d'extrémité avant (315, 415) entre l'extrémité avant (312, 410) de la plateforme (310, 410) et le bord d'attaque (322, 422) de la partie de profil aérodynamique (320, 420), et une dépression (330, 430) qui s'étend dans la plateforme (310, 410), et qui est située dans la région d'extrémité avant (315, 415).
