Summary: | The invention relates to a distributor (30) for a turbine (8) of a turbomachine (1). The distributor (30) comprises a radially internal platform (32), a blade (38) and a base (36) which is covered with a track (37) made of abradable material. According to the invention, the distributor (30) comprises a leakage gas reintroduction duct (40). The duct (40) comprises an inlet (42) through the track (37) made of abradable material, an outlet (46) which opens through a downstream surface (S4) of the base (36) and an intermediate duct portion which extends from the inlet (42) to the outlet (46). The intermediate duct portion is orientated with a tangential component.
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. |
