Abstract
An annular gas turbine engine combustion chamber including an outer wall and an inner wall connected by a wall forming the chamber bottom is disclosed. The walls delimit sources of combustion with axes inclined relative to the axis of the chamber. The chamber-bottom wall, of frustoconical shape, is pierced with orifices for the fuel injection systems, the planes of the orifices being perpendicular to the axes of the sources of combustion. The combustion chamber also includes heat-protection baffles centered on each of the orifices with a shoulder by which they rest against a flat surface portion along the periphery of the orifices. The chamber-bottom wall is conformed in a succession of adjacent flat facets having a common edge, with one facet per orifice, and the shoulder of the deflectors pressing against the plane of the facets.
