An actuator positioning convergent/divergent nozzle flaps is supported from a stiffner on a support structure. An interface fairing for separating possible hot gas flow from engine fumes is supported from the support structure at a location which avoids fairing deflecting as a function of stiffner deflection. Interference between the fairing and nozzle flap drive is thereby avoided.

In a gas turbine engine within an aircraft engine compartment an apparatus comprising: an augmentor duct conveying hot exhaust gas; a plurality of convergent nozzle flaps forming an adjustable convergent nozzle receiving gas from said augmentor duct; a plurality of external flaps surrounding said convergent nozzles in spaced relationship forming a flap chamber therebetween; a sync ring pivotally connected to said convergent nozzle and said external nozzle for adjusting the position of said nozzles; a static support structure circumferentially surrounding said augmentor duct, the upstream end of said support structure supported from said augmentor duct, a cylindrical stiffner at the upstream end of said support structure; an actuator supported at least in part from said stiffner and connected to said sync ring for providing an axial travel of said sync ring;, a cylindrical impervious lightweight fairing surrounding said support structure from said stiffner location to the location of the connection of said sync ring to said nozzle flaps; a plurality of finger seals located on said stiffner and sealingly biased against said fairing, whereby fumes from said engine compartment may not enter the space inside said fairing; and said fairing supported from said support structure at a support location on said support structure; said support location being upstream of the travel of said sync ring and downstream of said stiffner.
