FIELD: engines and pumps.
SUBSTANCE: annular wall is designed for being connected in transverse direction of longitudinal walls of annular combustion chamber of gas turbine engine and is essentially flat, and has an inclination relative to longitudinal axis of gas turbine engine and includes many deflectors. Each of deflectors is made in the form of flat and essentially rectangular plate. Deflectors are installed on annular wall, and each of them contains a hole for installation of fuel spray system and many perforated holes made opposite deflectors around their hole for passage of air intended to cool the deflectors. Each deflector contains forced direction devices of cooling air flow of deflectors in radial direction relative to longitudinal axis of gas turbine engine around fuel spray systems. Each deflector can contain at least two deformed sections, each of which forms partition directing the air cooling flow. Deformed sections are made in radial direction relative to longitudinal axis of gas turbine engine on both sides of deflector hole.
EFFECT: invention allows improving deflector cooling.
