초록 ▼

The invention relates to an annular combustion chamber for a turbomachine of axis X, in which the chamber end wall is fixed to inner and outer side walls by means of a plurality of radially-inner attachment fittings and by means of a plurality of radially-outer attachment fittings disposed upstream from said chamber end wall by bolting a zone of each of said fittings to said side walls. At least one of said pluralities of attachment fittings is integrated in a ring secured to the chamber end wall and comprises a plurality of pairs of tabs which extend upstream beyond the bolting zones, the two tabs in each pair being disposed circumferentially on either side of a bolting zone and being interconnected at their upstream end to the upstream end of a fixing plate which extends between said two tabs and which presents a bolting zone for being fixed to the adjacent side wall.

What is claimed is: 1. An annular combustion chamber for a turbomachine of axis X, the chamber comprising a radially-inner side wall, a radially-outer side wall, and a chamber end wall disposed between said inner and outer side walls in the upstream region of said chamber, said chamber end wall being fixed to said inner and outer side walls by means of a plurality of radially-inner attachment fittings and by means of a plurality of radially-outer attachment fittings disposed upstream from said chamber end wall by bolting a zone of each of said fittings to said side walls, wherein at least one of said pluralities of attachment fittings is integrated in a ring secured to the chamber end wall and comprises a plurality of pairs of tabs which extend upstream beyond the bolting zones, the two tabs in each pair being disposed circumferentially on either side of a bolting zone and being interconnected at their upstream end to the upstream end of a fixing plate which extends between said two tabs and which presents a bolting zone for being fixed to the adjacent side wall. 2. A combustion chamber according to claim 1, wherein the upstream ends of the tabs in a pair of tabs, and the upstream end of the associated fixing plate include portions of extra thickness for withstanding radial bending stresses. 3. A combustion chamber according to claim 2, wherein each tab is separated from the associated fixing plate by a slot opening out into a hole situated in the vicinity of the portion of extra thickness. 4. A combustion chamber according to claim 1, wherein the tabs are S-shaped between the ring and the bolting zone. 5. A combustion chamber according to claim 4, wherein the tabs are suitable for bearing against the adjacent side wall at least in the vicinity of the S-shape in order to limit the extent to which the chamber end wall can move relative to said side wall in the event of vibratory resonance. 6. A combustion chamber according to claim 1, wherein the ring is secured to the chamber end wall by welding. 7. A combustion chamber according to claim 6, wherein the ring is welded to the radially-inner edge of the chamber end wall and is separate from the radially-inner side wall by a gap serving to compensate for radial expansion differences between the chamber end wall and said side wall.
