Abstract (en)
[origin: EP1777458A1] The annular wall (6-8) for turbomachine combustion chambers has circumferential rows of primary air inlets (18) and dilution inlets (20). The wall is covered with circumferential rows of cooling inlets (22) which are smaller than the other inlets and are arranged in circumferential rows with an equal number of inlets. There is a row of larger cooling inlets (24) immediately downstream from the primary and dilution inlets. An independent claim is included for turbomachines fitted with the wall.
