FIELD: engines and pumps. ^ SUBSTANCE: diffusion chamber of gas turbine engine is arranged between external case and internal case of engine, supplied with air through inlet diffusion channel and includes combustion chamber of convergent type. Combustion chamber restricts external annular channel with external case and internal annular channel with internal case. Diffusion chamber includes the fairing partially covering external annular channel. Fairing includes the housing made in the form of round part formed with rotation about fairing axis. Housing is located between two planes which are essentially transverse to the above axis of fairing and has plane section. Also, the housing includes radial external end and radial internal end. Fairing includes external side starting from the above radial external end and radial internal side starting from radial internal end, as well as fasteners intended for its fixture on combustion chamber. The other objects of this invention is combustion chamber located in the above diffusion chamber, as well as gas turbine engine containing such diffusion chamber. ^ EFFECT: invention allows reducing pressure losses. ^ 14 cl, 10 dwg |
