  • Patent number: 8261556
    Abstract: A device for guiding an element in an orifice in a wall of a turbomachine combustion chamber is disclosed. The device includes a coaxial ring and bushing mounted one inside the other. The bushing includes two coaxial annular parts that are fastened to each other by welding and that define a groove for guiding a rim of the ring. Welding zones between the parts of the bushing are situated away from the path of the rim of the ring when moved along a privileged transverse direction of ring movement relative to the bushing when the combustion chamber is in operation.

  • Patent number: 7757495
    Abstract: A turbine engine annular combustion chamber includes inner and outer longitudinal walls connected upstream by a transverse chamber bottom and including a single-piece cowling covering the chamber bottom. Each of the longitudinal walls is inserted between corresponding flanges of the chamber bottom and of the cowling. The longitudinal walls, the chamber bottom and the cowling are assembled together by a plurality of first fixings between the longitudinal walls and the chamber bottom alternating with a plurality of second fixings distinct from the first fixings between the longitudinal walls and the cowling.

  • Patent number: 7673457
    Abstract: A turbine engine annular combustion chamber, including longitudinal walls connected by a transverse chamber bottom and a single-piece cowling, the chamber bottom and the cowling each including an inner flange and an outer flange each with a plurality of holes made in it for the passage of fixing systems for fixing the cowling on the chamber bottom. Each fixing system has associated with it at least one tangential slot formed on the corresponding flange of the chamber bottom and/or on the corresponding flange of the cowling, each slot being formed in the immediate vicinity of the corresponding fixing system.

  • Publication number: 20070180809
    Abstract: The invention concerns a turbine engine annular combustion chamber made up of inner (6) and outer (8) longitudinal walls connected upstream by a transverse chamber bottom (10) and comprising a single-piece cowling (12) covering said chamber bottom, the longitudinal walls (6, 8) each being inserted between corresponding flanges (22, 24; 26, 28) of the chamber bottom (10) and of the cowling (12). The longitudinal walls (6, 8), the chamber bottom (10) and the cowling (12) are assembled together by means of a plurality of first fixings (20a; 20b) between the longitudinal walls (6, 8) and the chamber bottom (10) alternating with a plurality of second fixings (20a; 20b) distinct from the first fixings between the longitudinal walls (6, 8) and the cowling (12).
