GAS-TURBINE ENGINE Russian patent published in 1998 - IPC

FIELD: mechanical engineering gas-turbine engines. SUBSTANCE: gas-turbine engine has stator and rotor with radial thrust bearing whose outer race is made in form of piston for axial displacement relative to stator and contacting at both sides with active load-bearing members. Radial clearance between working surfaces of race and bearing support is 0.1-0.4 mm. Radial clearance space communicates through holes with support space. EFFECT: provision of possibility to adjust radial and axial clearance and simultaneously damping vibrations. 3 cl, 5 dwg
