Abstract
An improved pressure balanced nonaxisymmetric high aspect ratio afterburner convergent nozzle of the type adapted to be mounted on a jet engine suspended from an airfoil's wing spar structure, and characterized by its simplicity of construction, ease and reliability of operation, and improved simplified sealing characteristics; yet, which permits substantial reduction of the included angle between the wing chord reference plane WCRP and the visual line-of-sight from the airfoil trailing edge into the jet engine nozzle while in its cruise position. More specifically, the present invention pertains to a simplified pressure balanced nonaxisymmetric high aspect ratio afterburner convergent nozzle construction which permits of simplified, highly effective sealing arrangements and wherein when the nozzle is shifted to a dry nozzle position--i.e., the cruise position--the trailing edge line-of-sight into the nozzle is maintained at a minimum angle, preferably on the order of from about 5.degree. to about 10.degree. as measured from the wing chord reference plane WCRP.
