ABSTRACT:
In a by-pass gas turbine engine, the by-pass exhaust flow is mixed with the core engine exhaust flow internally of the engine before passage through the final exhaust (propulsion) nozzle. The exhaust flow mixer comprises alternate inwardly and outwardly inclined substantially planar "fingers", which are arrayed around and attached to the circumference of the aft end of the core engine and extend generally downstream thereof. The fingers are effective to deflect the exhaust flows by virtue of the Coanda effect.
