OIL SYSTEM OF AIRCRAFT GAS TURBINE ENGINE WITH AFTERBURNER CHAMBER Russian patent published in 2019 - IPC F02C7/06 

FIELD: machine building.

SUBSTANCE: invention relates to machine building, particularly, to oil system of aircraft gas turbine engine (GTE) with augmenter mounted on supersonic maneuvering aircraft. Technical result is achieved due to that known oil system of aviation GTE with afterburner chamber comprises siphon gate installed in oil supply line, which rising branch is connected via second output of controlled two-position valve with oil cavity of section of two-section fuel-oil heat exchanger, fuel cavity of which is communicated with main line of fuel supply to main combustion chamber, and falling branch is interconnected with oil cavity of section of two-section fuel-oil heat exchanger, fuel cavity of which is interconnected with main line of fuel supply into augmenter combustion chamber. Controlled throttle is installed in the main line communicating the siphon gate loop with the oil tank.

EFFECT: technical result of invention is increase in GTE operation reliability by simplifying throttle adjustment and providing stability of oil supply pressure at start-up.
