Abstract
An exhaust nozzle of a gas turbine engine effective for reducing the emission of infrared radiation and providing an extensive maneuvering capability. The nozzle preferably is of the two-dimensional type and includes an exhaust cowl with a generally rectangular cross-sectional exhaust opening and a plug within the downstream end of the cowl. The plug, which is preferably wedge-shaped, is pivotable about a transverse axis running through the aft portion of the plug by an appropriate means, for example, a cam or a screw jack mechanism. The nozzle can also include blocker doors and louvers for providing thrust reversal.
