Transverse wall of a combustion chamber provided with multi-perforation holes

Annular wall (10) intended to connect transversely longitudinal walls (6, 8) of an annular combustion chamber (4) of a turbine engine, said wall (10) being essentially flat, inclined in relation to a longitudinal axis (X-X) of the turbine engine, and comprising:

• a plurality of deflectors (16), each formed by an essentially rectangular flat sheet, said deflectors being mounted on the annular wall (10) and each comprising an aperture (17) for the installation of a fuel injection system (14);
• and
• a plurality of multi-perforation holes (18) formed in relation to the deflectors (16) around their aperture (17) so as to allow a passage of air intended for the cooling of the said deflectors;
• characterised in that each deflector (16) comprises means to force the flow of air for cooling the deflectors to flow radially in relation to the longitudinal axis (X-X) of the turbine engine around the fuel injection systems.
