Abstract

The by-pass exhaust flow 17 is mixed with the core engine exhaust flow 19 internally of the engine before passage through the final exhaust (propulsion) nozzle 13. The exhaust flow mixer 11 comprises alternate inwardly and outwardly inclined substantially planar "fingers" 27 and 29 respectively, which are arrayed around and attached to the circumference of the aft end of the core engine and extend generally downstream thereof. <IMAGE>
