Abstract
L’invention se rapporte à une aube (60) et un élément d’étanchéité (59) formant un ensemble pour turbine de turbomachine. L’aube (60) comprend une pale (61) et une plateforme (62) à laquelle est relié l’élément d’étanchéité (59). Un canal interne (80) traverse la plateforme (62) de manière à prélever du fluide circulant dans un conduit primaire (21A) qu’elle délimite et à injecter le fluide ainsi prélevé dans une cavité inter-léchettes (50A, 51A) délimitée par l’élément d’étanchéité (59). L’invention permet de réduire la formation et l’intensité d’écoulements secondaires tout en améliorant l’étanchéité. Figure pour l’abrégé : Fig. 5
