An exhaust nozzle for an engine in which the exhaust opening is defined by spaced flap assemblies and side members. The flap assemblies are pivotable to permit variation in the size and shape of the opening. The nozzle includes actuation means having an output and pivoting means for transforming the output into pivotal movement of the flap assemblies. Cams are included on the flap assemblies to provide at least a portion of the pivotal movement.

An exhaust nozzle mounted downstream of and adjacent to an exhaust casing of an engine comprising: (a) a plurality of spaced flap assemblies, each flap assembly comprising: (i) a convergent flap having an upstream end pivotally connected with said exhaust casing; and (ii) a divergent flap having an upstream end pivotally connected with a downstream end of said convergent flap and including camming means defined at each transverse side of the outer surface thereof; (b) at least one actuation means having an output effective for rotating a plurality of rotatable shafts; and (c) a plurality of pivoting means for transforming the output of respective ones of said plurality of rotatable shafts of said actuation means through engagement with said camming means into pivotal movement of respective ones of said flap assemblies, each of said plurality of pivoting means comprising: (i) a crank having one end fixedly connected with one of said rotatable shafts and an opposite end having a follower thereon for engaging said camming means of a respective divergent flap for effecting pivotal movement thereof; (ii) a link arm having one end pivotally connected with an intermediate portion of said crank and an opposite end pivotally connected with said downstream end of a respective convergent flap for effecting pivotal movement thereof.
