Abstract
Multiported and multinozzled sectors are pivotally mounted to swing between positions cooperatively spanning a jet engine exhaust duct and retracted positions alongside the wall of such duct. Such sectors are located between a forward nozzle section and a rearward nozzle section deformable to alter the contour of the passage through the exhaust duct. Such nozzle sections and noise suppressor sectors are located rearwardly of a thrust reverser. Each nozzle is of elongated cross section, preferably being elliptical, and arranged so that the greater dimension or major axis extends substantially radially of the noise suppressor sector. The nozzles are dimensioned, proportioned and arranged to provide adequate flow through them and to afford space between the nozzles to facilitate flow of ventilating air to mix equally with the exhaust gas flowing through all the nozzles at least in the central portion of the noise suppressor.
