THE EJECTOR HAS FLUID DUCTS FOR RECEIVING AND CONVEYING THE ENGINE EXHAUST AND DIVIDING THE EXHAUST FLOW INTO JET SHEETS. COANDA AIRFOILS ARE ARRANGED ADJACENT THE FLUID DUCTS FOR ENTRAINING THE AMBENT AIR INTO THE EXHAUST FLOW OVER THEIR EXTERIOR SURFACES AND FOR ROTATING THE FLOW THROUGH APPROXIMATELY 90*. A MIXING CHAMBER IS ARRANGED DOWNSTREAM OF THE AIRFOILS FOR RECEIVING AND MIXING THE ROTATED JET SHEETS ALONG WITH WITH MEANS FOR DIFFUSING AND CONTROLLING THE BOUNDARY LAYER OF THE MIXED FLOW.
