Abstract (en)
[origin: WO2013175126A2] The dilution holes (39) in a shell ring (2, 3) of a turbomachine combustion chamber are covered with platelets (40) which delimit chambers (49) around them on the interior face of the shell ring. Ventilation holes (45), passing through the platelet, cause those portions of the shell ring surrounding the dilution holes (39) to be ventilated, cooling these portions and preventing crack formation.
