Abstract RU 2141036 C1

FIELD: mechanical engineering; gas-turbine engine. SUBSTANCE: proposed turbine has main disks with cooled working blades and intermediate disks, including rim with axial projection. Channel is made in axial projection of rim opposite to each working blade. Generatrix of surface of channel peripheral part is arranged tangentially to generatrix of rim inner surface made in form of arc and is directed to engine blading side. EFFECT: enhanced reliability of turbine owing to prevention of contamination of rim of intermediate disk by cooling air. 2 dwg
