초록

An external jet nozzle mixer includes identically formed lobes. The external mixer works with the internal mixer further to mix the engine internal bypass flow with the internal jet engine core flow to level the disparate 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 reduce noise. The internal lobe contours act as lifting flutes, causing mixing of the primary hot and cold flows to mix before exiting the nozzle. The external lobe contours act...

청구항

What is claimed is: 1. A method of retrofitting a pre-existing engine assembly, comprising: providing a pre-existing engine enclosed within a housing, which is coupled to a pre-existing thrust reverser, and a first stage mixer coupled to the pre-existing engine and being located within the housing, the first stage mixer including first stage elements to mix exhaust gas with cooling air, the housing having an exhaust aperture, the pre-existing thrust reverser coupled to the housing and having a pre-existing stowed position fixed relative to the housing a...
