TURBINE ASSEMBLY IN TURBINE ENGINE Russian patent published in 2017 - IPC F01D25/12 F01D9/06 F02C7/18 

FIELD: engine devices and pumps.

SUBSTANCE: turbine assembly in turbine engine having an outer housing, an inner housing, an annular exhaust gas path defined between outer and inner walls of the flow path, and a cavity of turbine exhaust casing. A plurality of structural braces supports the inner housing on the outer housing. Fairing surrounds each of the braces in a region extending between the outer and inner walls of the flow path. The first path of the purge air conducts cooling purge air radially inward towards the inner housing. The second purge air path conducts the cooling purge air radially outward to provide purge air flow to the position of the cavity of the exhaust casing radially outward from the outer wall of the flow path. The embodiment of the turbine assembly in the turbine engine is also presented.

EFFECT: invention makes it possible to provide thermal protection of the turbine assembly exhaust casing.
