Abstract
Each duct of a plurality of generally cylindrical exhaust ducts disposed in approximately uniform annular arrangement about an axis is a tube, or a lobe of a radially-branched passage, having a discharge end canted so that the radially outer portion of such duct end projects rearward farther than any other portion of the duct end. The canted duct ends direct the major portion of the exhaust of a jet engine inward toward the axis of the annular exhaust duct arrangement in a plurality of exhaust jets, effecting a rearwardly convergent relationship of the jets.
