A gas turbine engine comprising a nacelle and a breather duct. The breather duct provides communication between a component of the engine within the nacelle and the exterior of the nacelle and opens at an exhaust port on the external surface of the nacelle. There is a clean air outlet slot located downstream of the exhaust port and arranged to expel, in use, a sheet flow of clean air to form an aerodynamic barrier between the external surface of the nacelle and a flow of breather air expelled from the exhaust port.


1. A gas turbine engine for use with an oil lubricated engine component, the gas turbine engine comprising: a nacelle that defines an exterior and an external surface;a breather duct providing communication between the engine component within the nacelle and the exterior of the nacelle, the breather duct opening at an exhaust port on the external surface of the nacelle; anda clean air outlet slot opening on the external surface of the nacelle, located downstream of the exhaust port, and arranged to expel, in use, a sheet flow of clean air to form an aero...
