AXIAL-FLOW COMPRESSOR PRESSURE DIFFUSER Russian patent published in 2004 - IPC

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in axial-flow compressors of gas-turbine plants with built-in combustion chambers arranged vertically relative to machine axis. To increase efficiency of compressor calculated by parameters of braking in branch pipes, axial part of diffuser is made with use of straight-line conical surfaces with angles of opening of shell and fairing equal to at ratio of outlet and inlet areas of said part . Turnable section is made with ratio of areas in section at ratio of radii of fairing and shell , and relative width of diffuser as a whole being h/b=0.94-0.97 where h and b height of channel and width of diffuser at inlet and outlet.

EFFECT: increased efficiency of compressor.
