FIELD: mechanical engineering; gas-turbine engines.
SUBSTANCE: proposed turbine of gas-turbine engine is made with support of roller bearing and cooled working blades of first and second stages whose inner spaces are connected with compressor output through intermediate spaces by pipes. Support of roller bearing is provided with inclined wall to which S-shaped flexible flange with cylindrical and radial walls is butt pointed to form circular closed space connected at input by pipes with compressor intermediate stage and at output, with inner space of second working blade. Inclined branch pipes are installed in circular space to connect inner of first working blade with compressor output by pipes. Branch pipes are installed telescopically relative to pipes and inclined wall of support.
EFFECT: improved reliability and economy of engine.
