An external jet nozzle mixer (20) includes identically formed lobes (48), equal in number those of the internal mixer (42). External mixer (20) works with internal mixer (42), further to mix the engine internal bypass flow with the internal jet engine core flow, to level the disparate exhaust flow velocities, to reduce the peak velocities from the jet engine core and increase the lower bypass velocities of the engine internal bypass flow, and thereby to reduce noise. The internal lobe contours act as lifting flutes, causing mixing of the primary hot and ...
1. In a nozzle for a jet engine enclosed within a tubular housing and also having an existing first stage mixer within said housing which includes a number of first stage lobes, and having a thrust reverser having a stowed position fixed relative to the tubular housing and having a deployed position, the improvement comprising a second stage mixer coupled to the exhaust aperture of said tubular housing to receive gas exhausted from the first stage mixer, said second stage mixer having a plurality of identically formed lobes which equal in number those of...
