  • ENGINE NOZZLE SYSTEM FOR SHOCK-CELL NOISE REDUCTION
    Publication number: 20170082063
    Abstract: A method and apparatus for reducing noise generated during operation of a propulsion system. In one illustrative embodiment, a nozzle system comprises a first nozzle and a second nozzle at least partially surrounded by the first nozzle. An outer surface of an aft portion of the second nozzle has a shape configured such that a radial cross-section of the outer surface of the aft portion of the second nozzle has a curve that is different from at least one other curve for another radial cross-section of the outer surface of the aft portion of the second nozzle and such that an axial cross-section of the outer surface of the aft portion of the second nozzle has a wavy shape.
