Gas turbine rotor cooling system uses cooled space outlets linked to flowed turbine space and arranged in blade flange parts in flowed nozzle area.

摘要

The air-cooled space (1) communicates via the outlet holes (3) with the flowed area of the turbine (6), the outlets (3) placed on the blade (2) flanges (5) where these reach into the flowed area of the nozzle (6). The axes (9) of the outlets run along the inside of the rotor ring (4) towards the center line of the blade outlet profile. In operation, air flows from space (1) via the outlets to cool off the ring (4).
