Abstract:
1. An arrangement for discharging oil-contaminated exhaust air separated by a lubricating oil de-aeration system of a gas-turbine engine, comprising: an attenuation chamber formed within an exhaust cone of the gas-turbine engine for connecting to an oil-contaminated exhaust air venting line of the lubricating oil de-aeration system; a Venturi nozzle being arranged in an exhaust-gas flow in an exhaust flow duct of the gas-turbine engine and oriented in a flow direction such that a portion of the exhaust-gas flow flows through the Venturi nozzle; a discharge tube connecting the attenuation chamber to the Venturi nozzle so that the Venturi nozzle draws off oil-contaminated exhaust air from the attenuation chamber and introduces the oil-contaminated exhaust air into the exhaust-gas flow.
