Abstract: 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.

Abstract: A device for attaching manifolds for cooling the casing of a preferably low-pressure turbine of a turbine engine by air jets. The device includes a mounting for the manifolds, shaped such as to keep the manifolds spaced apart from one another. A plurality of elements support the manifold mounting, each supporting element being attached to the casing, and connected to the manifold mounting by a connector. The device includes N cooling manifolds and N-1 supporting elements, each supporting element being arranged between two adjacent cooling manifolds.

Abstract: A turbine engine, a turbojet, or a turboprop engine, including an annular combustion chamber defined by an inner shell and an outer shell, a turbine distributor arranged downstream of the combustion chamber, with a downstream end of the outer shell and/or of the inner shell of the chamber including a radial rim arranged opposite a radial rim of an upstream end of the distributor, a sealing mechanism including at least one strip extending between the rims to provide a seal between the combustion chamber and the distributor. The sealing strip extends axially and circumferentially between the rims and bears sealingly against free ends of the rims.
