The casing (30) has an annular combustion chamber (10) delimited by metallic annular walls e.g. internal and external revolution walls (12, 14) and a high-pressure turbine dispenser (20) including annular internal and external platforms (22, 24) secured to a downstream end of the walls. The platforms are made of metal and are formed from a single piece with the walls. The platforms are welded onto the walls of the combustion chamber. The dispenser has a set of guide blades (26) extending radially between the platforms, where the blades are spaced circumferentially with respect to each other. |
