TURBOMACHINE COMBUSTION CHAMBER PROVIDED WITH AIR DEFLECTION MEANS FOR REDUCING WAKE CREATED BY IGNITION PLUG Russian patent published in 2018 - IPC F23R3/50 F23R3/04 

FIELD: internal combustion engines.

SUBSTANCE: combustor module for a turbomachine comprises a closed annular space, an annular combustion chamber, a spark plug. Annular combustion chamber is housed in said closed annular space and has at least one annular wall delimiting said combustion chamber and having an opening for installing a spark plug, and a plurality of micro-openings for entry of cooling air into said combustion chamber for cooling said annular wall. Combustor module receives an air flow from a turbine engine compressor and said air generally flows from upstream to downstream of the combustion chamber within said closed annular space. Part of the air flow bypasses the combustion chamber along said annular wall and blowing said spark plug, thereby creating a wake. Combustor module further comprises deflecting means extending from upstream to downstream, approaching a central plane of said wake and approaching said annular wall of the combustion chamber, so as to deflect a portion of the air blowing the spark plug toward the central plane of said wake and towards said annular wall.

EFFECT: invention is aimed at increasing the cooling efficiency of the annular wall.
