Abstract

L'invention concerne un carter inter-turbine (118) de turboréacteur, comprenant une virole extérieure (2), une virole intérieure (6), des bras radiaux (8) reliant la virole extérieure et la virole intérieure, des carénages (10) ayant une forme profilée et disposés dans la veine d'écoulement (4) autour des bras radiaux, et un circuit de refroidissement et de ventilation comprenant un collecteur extérieur (12) positionné autour de la virole extérieure pour recevoir de l'air et communiquant avec l'intérieur des carénages, une pluralité de premiers perçages (14) réalisés dans un bord de fuite (10b) des carénages (10) et formant un premier débit d'air calibré destiné à être évacué dans la veine d'écoulement, un collecteur intérieur (16) positionné autour de la virole intérieure et communiquant avec l'intérieur des carénages pour collecter le restant de l'air injecté à l'intérieur des carénages, le collecteur intérieur comprenant au moins un deuxième perçage (18) formant un deuxième débit d'air calibré destiné à alimenter en air de ventilation une cavité de purge (20) en aval du carter inter-turbine.The invention relates to an inter-turbine casing (118) for a turbojet engine, comprising an outer shell (2), an inner shell (6), radial arms (8) connecting the outer shell and the inner shell, fairings (10) having a contoured shape and arranged in the flow vein (4) around the radial arms, and a cooling and ventilation circuit comprising an outer manifold (12) positioned around the outer shell for receiving air and communicating with inside the fairings, a plurality of first holes (14) made in a trailing edge (10b) of the fairings (10) and forming a first calibrated air flow intended to be evacuated in the flow duct, a manifold interior (16) positioned around the inner shell and communicating with the interior of the fairings to collect the remainder of the air injected inside the fairings, the internal manifold comprising at least one second bore (18) forming a second flow of calibrated air intended to supply ventilation air to a purge cavity (20) downstream of the inter-turbine casing.
