Abstract:
A nozzle for exhausting a gas jet from a gas turbine engine comprising:an exhaust duct for channeling said jet along an inner surface thereof; a plurality of adjoining chevrons disposed at an aft end of said duct to define an exhaust outlet; each of said chevrons being triangular in configuration, with a base fixedly joined to said duct aft end laterally coextensively with adjacent chevron bases, an opposite apex, a pair of laterally opposite trailing edges converging from said base to said apex, and radially opposite outer and inner surfaces bounded by said trailing edges and base, with said chevron inner surfaces at said bases being laterally and radially coextensive with said duct inner surface; said trailing edges of adjacent chevrons being spaced laterally apart to define respective laterally diverging slots disposed in flow communication with said duct for channeling flow radially therethrough; and said chevrons having a compound concave contour both axially between said bases and apexes and laterally between said trailing edges thereof to define a bowl in one of said outer and inner surfaces thereof.
