<p>A jet engine nozzle exit configuration includes a turbofan engine exhaust nozzle that includes first and second internal flow surfaces. The first internal flow surface is positioned to receive a fan flow and terminates at a first exit aperture having a first perimeter. The first perimeter includes multiple first projections extending in an aft direction, with an aft portion of individual neighboring first projections spaced apart from each other by a gap, and with a geometric feature of the multiple first projections varying in a first manner along a portion of the first perimeter. The second internal flow surface is positioned to receive an engine core flow and terminates at a second exit aperture having a second perimeter including multiple second projections extending in an aft direction, with an aft portion of individual neighboring second projections spaced apart from each other by a gap, and with a geometric feature of the multiple second projections varying in a second manner different than the first manner along a portion of the second perimeter.</p> |
