Title
(EN) DEVICE FOR COOLING A TURBINE CASING FOR A TURBOMACHINE
(FR) DISPOSITIF DE REFROIDISSEMENT D'UN CARTER DE TURBINE POUR UNE TURBOMACHINE
Abstract
(EN)
The invention relates to a device (9) for cooling a turbine casing (7) for a turbomachine, for example an aircraft turbojet engine, which extends about an axis (X) and comprises air distributing means configured to take in air and convey it to the casing, the air distributing means comprising at least a first ramp section (20) and a second ramp section (20) which extend circumferentially about the axis (X), respectively on a first circumferential portion and on a second circumferential portion which differ from one another, each ramp section (20) comprising air ejection openings designed to be oriented towards the casing for the purpose of cooling same, and characterised in that it comprises adjustment means (23) capable of adjusting the flow rate of air ejected at the first ramp section (20) with respect to the flow rate of air ejected at the second ramp section (20).
(FR)
L'invention concerne un dispositif de refroidissement (9) d'un carter (7) de turbine pour une turbomachine, telle par exemple qu'un turboréacteur d'avion, s'étendant autour d'un axe (X) et comportant des moyens de distribution d'air configurés pour prélever de l'air et l'acheminer vers le carter, les moyens de distribution d'air comprenant au moins une première rampe (20) et une deuxième rampe (20) s'étendant circonférentiellement autour de l'axe (X), respectivement sur une première portion circonférentielle et sur une seconde portion circonférentielle différentes l'une de l'autre, chaque rampe (20) comportant des orifices d'éjection d'air destinés à être orientés vers le carter pour le refroidir, caractérisé en ce qu'il comporte des moyens de réglage (23) aptes à régler le débit d'air éjecté au niveau de la première rampe (20) par rapport au débit d'air éjecté au niveau de la seconde rampe (20).
