COMBUSTION CHAMBER WALL Russian patent published in 2017 - IPC F23R3/06 

FIELD: machine building.

SUBSTANCE: turbomachine combustion chamber annular wall comprises cold side and hot side and has, at least, one primary hole to enable possibility of first air flow ingress, passing on wall cold side, to wall hot side for providing fuel combustion inside combustion chamber and plurality of cooling holes. Each cooling hole has diameter of not more than 1 mm in order to enable possibility of second flow of air ingress, passing on wall cold side, to wall hot side for wall hot side cooling. Plurality of cooling holes is also suitable for dilution of combustion gas, which is result of said combustion, due to use of air flow ingression on wall hot side through cooling holes. Said cooling holes represent not less than 50 % of entire surface area for air passage through wall.

EFFECT: invention is aimed for provision of more uniform temperature distribution inside combustion chamber at simultaneous increase of turbomachine hydro-dynamic cycle efficiency.
