GAS TURBINE ROTOR Russian patent published in 2010 - IPC F01D5/08

Abstract RU 2378517 C1

FIELD: engines and pumps.

SUBSTANCE: invention relates to gas turbines rotors. Proposed rotor comprises a disk and baffle fitted and fixed thereon with the help of bayonet joint relative to said disk, and double labyrinth arranged on rotor shaft, on baffle side. Baffle hub inner surface accommodates annular rib directed towards rotor axis with its flat section fixed between turbine disk hub and said double labyrinth. Through channels are made in said annular rib between its flat section and baffle hub to force cooling air and make radial ribs between channels to accommodate axial pins to lock baffle along circumference.

EFFECT: higher reliability thanks to boltless joints cooling air feed onto rotor vanes.
