COMBUSTION CHAMBER DOUBLE-ROW RADIAL DIFFUSER Russian patent published in 2024 - IPC F23R3/00 

FIELD: engine building.

SUBSTANCE: proposed design relates to gas turbine engines (GTE) of aviation application, in particular to design of radial diffuser of combustion chamber located behind diagonal stage of compressor. Combustion chamber double-row radial diffuser consists of inner and outer shells and guide vanes. Inner and outer shells are provided with slots corresponding to the profile of guide vanes of the first row, in which guide vanes of the first row are installed. Inner surface of inner shell contacts with flanges of guide vanes, which are fixed by thrust ring fixed on inner shell by means of bolted joints. Guide vanes of the first row contain slots, in which brackets are installed, contacting with external surface of outer shell. Between ends of guide vanes and spacer screws installed in flange of outer shell there are thrust semi-rings. Cavity above the outer shell is filled with sealing material.

EFFECT: higher gas-dynamic stability of the compressor, as well as the diffuser manufacturability and maintainability.
