Abstract
L’invention concerne un distributeur (30) pour turbine (8) de turbomachine (1). Le distributeur (30) comprend une plateforme radialement interne (32), une pale (38) et un pied (36) qui est revêtu d’une piste en matériau abradable (37). Selon l’invention, le distributeur (30) comprend un conduit (40) de réintroduction de gaz de fuite. Le conduit (40) comprend une entrée (42) à travers la piste en matériau abradable (37), une sortie (46) débouchant à travers une surface aval (S4) du pied (36), et une portion intermédiaire de conduit qui s’étend depuis l’entrée (42) jusqu’à la sortie (46). La portion intermédiaire de conduit étant orientée avec une composante tangentielle. Figure 3
