ASSEMBLY OF ANNULAR COMBUSTION CHAMBER OF GAS TURBINE ENGINE Russian patent published in 2020 - IPC F23R3/46 

FIELD: machine building.

SUBSTANCE: assembly (1) of combustion chamber of annular type is located around axis, which determines axial direction (A), and comprises annular flame tube (4), annular housing (2). Annular housing envelopes plurality of nozzles (3) and annular cavity (5). Plurality of nozzles (3) is arranged circumferentially around axis inside annular housing (2). Annular cavity (5) is formed between housing (2), plurality of nozzles (3) and annular flame tube (4) and serves for passage of compressed fluid medium (6) along it. Inside annular housing (2) there are multiple stiffening ribs (10). Two adjacent nozzles (3) are separated by one of said stiffness ribs (10). Assembly (15) of partition of combustion chamber separates annular cavity (5) from annular flame tube (4) and has holes (16) for plurality of nozzles (3). Siffening ribs (10) are located at an angle, in particular perpendicular, and are connected to combustion chamber partition assembly (15) by two boundary walls (44) of housing (2), and additional plates (20, 21) located in annular cavity (5). Annular housing (2) also surrounds annular flame tube (4).

EFFECT: invention is aimed at the combustion chamber design simplification.
