Abstract:
1. A method of directing the flow of gases in a two-dimensional exhaust nozzle assembly for an engine, the method comprising: a) translating a translatable structure between a plurality of operational positions relative to a pair of longitudinally extending sidewalls and a bottom wall of an exhaust duct having a flow diverting port therein, wherein the translatable structure is operable to open and close the flow diverting port, and wherein the plurality of operational positions includes a first operational position wherein the flow diverting port is effectively fully closed, a second operational position wherein the flow diverting port is effectively fully opened, and first intermediate position intermediate the first and second operational positions wherein the flow diverting port is effectively fully closed, and wherein the second operational position is generally rearward of the first operational position; and b) during at least a part of (a), varying a cross-sectional area of the exhaust duct at a throat constriction in the exhaust duct, wherein the throat constriction is at least partly defined by an inner portion of the translatable structure.
