Abstract: An annular wall which transversely connects longitudinal walls of an annular combustion chamber of a turbine engine is disclosed. The wall is essentially flat, inclined in relation to a longitudinal axis of the turbine engine, and includes a plurality of deflectors, each formed by an essentially rectangular flat sheet. The deflectors are mounted on the wall and each includes an aperture for the installation of a fuel injection system, a plurality of multi-perforation holes formed in relation to the deflectors around their aperture so as to allow a passage of air intended for the cooling of the deflectors, and a flow forcing unit which forces the flow of air for cooling the deflectors to flow radially around the fuel injection systems.

Abstract: The invention relates to an annular wall (10) intended to connect transversely longitudinal walls of an annular combustion chamber of a turbine engine. The wall (10) is essentially flat, inclined in relation to a longitudinal axis of the turbine engine, and comprises a plurality of deflectors (16), each formed by an essentially rectangular flat sheet. The deflectors are mounted on the wall and each comprise an aperture for the installation of a fuel injection system, a plurality of multi-perforation holes (18) formed in relation to the deflectors (16) around their aperture so as to allow a passage of air intended for the cooling of the deflectors, and means (20) to force the flow of air for cooling the deflectors to flow radially around the fuel injection systems.
