OUTLET DEVICE OF TURBINE OF AIRCRAFT GAS-TURBINE ENGINE Russian patent published in 2013 - IPC F01D25/30

Abstract RU 2472003 C1

FIELD: engines and pumps.

SUBSTANCE: turbine outlet device includes hollow shaped housing posts arranged in flow part after impeller of turbine final stage. Centre lines of outlet sections of post profiles are directed along longitudinal axis of turbine. Exit edge of each shaped post in circumferential direction of turbine cross section is arranged opposite entry edge of previous shaped post. Centre lines of entry sections of post profiles are turned to longitudinal turbine axis towards rotation of impeller of turbine final stage through an angle of 20-40°.

EFFECT: invention allows reducing infrared emission from moving blades of turbine final stage towards the engine outlet.
