Title (EN) DEVICE FOR COOLING A TURBINE CASING WITH AIR JETS
(FR) DISPOSITIF DE REFROIDISSEMENT PAR JETS D'AIR D'UN CARTER DE TURBINE
Abstract: front page image
(EN)The invention relates to a device (2) for cooling a turbine casing, preferably of a low-pressure turbine of a turbomachine, with air jets, the device comprising a pressurised air supply housing (3) and at least two curved cooling pipes (40) arranged on either side of the housing (3), around and spaced apart from a part of the casing and provided with air injection holes (41), the housing comprising, in particular, a bottom (31) and two longitudinal side walls (32, 33), and the bottom being pierced by air injection holes. The device is characterised in that each of the side walls extends outwards as at least one single-piece tubular sleeve, to which a cooling pipe is joined, the bottom of the sleeve being located at the same level as the bottom of the housing at the point where they are joined together.
(FR)L'invention concerne un dispositif de refroidissement (2) par jets d'air du carter d'une turbine, de préférence basse pression, d'une turbomachine, comprenant un boîtier d'alimentation (3) en air sous pression et au moins deux tubes de refroidissement (40) incurvés, disposés de part et d'autre dudit boîtier (3), autour et à distance d'une partie du carter et étant muni d'orifices d'injection d'air (41), ledit boîtier comprenant notamment un fond (31 ), et deux parois latérales longitudinales (32, 33), et ce fond étant percé d'orifices d'injection d'air. Ce dispositif est remarquable en ce que chacune desdites parois latérales se prolonge vers l'extérieur par au moins un manchon tubulaire monobloc et auquel un tube de refroidissement est raccordé, le fond du manchon étant au même niveau que ledit fond du boîtier à l'endroit où ils se rejoignent.
