Abstract

L'invention concerne un dispositif (9) de refroidissement d'un carter de turbine pour une turbomachine, telle par exemple qu'un turboréacteur d'avion, comportant des moyens de prélèvement et d'amenée d'air (10, 11, 15, 16), des moyens de distribution de l'air prélevé comprenant au moins une rampe (20a, 20b) s'étendant circonférentiellement autour de l'axe (X) de la turbomachine, ladite rampe (20a, 20b) étant reliée aux moyens de prélèvement et d'amenée d'air (10, 11, 15, 16) par une zone de liaison (19), ladite rampe (20a, 20b) comportant des orifices répartis le long de la rampe (20a, 20b), l'air prélevé étant destiné à s'échapper desdits orifices pour refroidir le carter, caractérisé en ce que la répartition des orifices le long de la rampe (20a, 20b) est telle que la densité des orifices est plus importante dans une zone de la rampe (20a, 20b) éloignée de la zone de liaison (19) que dans une zone de la rampe (20a, 20b) proche de la zone de liaison (19).The invention relates to a device (9) for cooling a turbine casing for a turbomachine, such as for example an aircraft turbojet engine, comprising means for taking off and supplying air (10, 11, 15 , 16), means for distributing the withdrawn air comprising at least one ramp (20a, 20b) extending circumferentially around the axis (X) of the turbomachine, said ramp (20a, 20b) being connected to the means air intake and delivery (10, 11, 15, 16) by a connection zone (19), said ramp (20a, 20b) having orifices distributed along the ramp (20a, 20b), l the sampled air being intended to escape from said orifices to cool the casing, characterized in that the distribution of the orifices along the ramp (20a, 20b) is such that the density of the orifices is greater in an area of the ramp (20a, 20b) distant from the connection zone (19) than in a zone of the ramp (20a, 20b) close to the connection zone (19).
