TURBINE OF GAS-TURBINE ENGINE Russian patent published in 1995 - IPC

Abstract RU 2028460 C1

FIELD: gas-turbine engines. SUBSTANCE: elastic damping mounts of rotor are released from gravitational forces due to creation of transverse static gas force in labyrinth seals. These seals have segments with ribs arranged in honeycomb manner and facing rotor surface. Segment arranged so that they oppose reaction of gravitational forces have their ribs spaced apart in axial direction at different distances. Formula is given to determine these distances. EFFECT: improved design. 6 dwg
