OIL LEAKS PROTECTION DEVICE TO THE GAS TURBINE ENGINE TURBINE ROTORS SIDE Russian patent published in 2018 - IPC F01D25/18 F02C7/28 

FIELD: machine building.

SUBSTANCE: invention relates to the oil leakage protection device in the turbine (2) rotors direction of the gas turbine engine comprising inlet cavity (18) configured to circulate the air / oil mixture therein, at that, at the outlet the said input cavity is limited by the turbine rotor trunnion (8) and from the outside is by the trunnion sealing flange (14) axially passing to the input, output cavity (20) opening towards the turbine discs (12) and communicating with the inlet cavity through plurality of made in the trunnion ventilation openings (22), and input annular reflector (24) fixed to the trunnion sealing flange and radially passing inwards towards the ventilation openings. At that, the input reflector comprises oil flow holes (26) formed at its end level, fixed on the trunnion sealing flange. Also presented is the gas turbine engine turbine comprising oil leakage protection device and comprising such turbine gas turbine engine.

EFFECT: invention allows to protect the turbine rotors from the risks of oil ignition.
