Abstract RU 2626876 C2

FIELD: machine engineering.

SUBSTANCE: turbomachine combustion chamber shell contain dilution holes (39), ventilation holes (38) which surround the dilution holes (39) and are thinner and more numerous than the last ones. The shell contains plates (40), running over and around the dilution holes (39) on the outside of the shell (2, 3). The shell lacks ventilation holes (38) in parts beneath the plates. Each plate contains a ledge (42) fastening to the shell and a hole (43), running over one of the respective dilution holes. Holes (45) pass through the plates. The holes are directed towards said parts of the shell.

EFFECT: increased cooling efficiency and improved ventilation.
