A two-dimensional nozzle for directing the exhaust of a gas turbine engine includes two spaced apart vertical sidewalls (16), an upper flap assembly (18) and a lower flap assembly (20). The upper flap assembly (20) includes at least a dorsal flap (22) pivotable about a first fixed axis (24). The lower flap assembly (20) includes a ventral flap (28) centrally pivotable about a second fixed axis (30) for creating a dual throat exhaust flow path.

An exhaust nozzle for directing a flowing stream of gas, including an exhaust duct comprising: two opposed, spaced apart sidewalls; an upper flap assembly disposed between the two sidewalls; and a lower flap assembly disposed between the two sidewalls, the lower flap assembly, the upper flap assembly, and the two sidewalls together defining a flow path for the gas stream, the upper flap assembly including a dorsal flap having a fore edge and an aft edge and being pivotable about a first fixed axis disposed within the gas flow path and extending between the two sidewalls, and a downstream flap, having a fore edge and an aft edge, the fore edge of the downstream flap being pivotally connected to the aft edge of the dorsal flap for cooperatively defining a movable exhaust gas directing barrier, the lower flap assembly including a ventral flap having a fore edge and an aft edge and being rotatable about a second fixed axis disposed intermediate the fore and aft edges thereof and extending between the two sidewalls; a fixed dorsal wall, disposed between the two sidewalls and extending downstream adjacent the upper flap assembly; means, slidably engageable between the dorsal wall and the dorsal flap, for sealing against gas leakage therebetween; a first actuator, including a first pair of disks each disposed adjacent one of the two sidewalls, the first pair of disks cooperatively supporting the dorsal flap therebetween and being each centrally rotatable about the first fixed axis; a linkage assembly, including a fairing link having a first end engaged with the aft end of the downstream flap, and a second end; a connecting link, having a first end engaged with the fairing link second end, and a second end engaged with the dorsal flap; and a thrust link, having a first end connected to a second actuator and a second end engaged with either the connecting link or the fairing link for selectably positioning the downstream flap.
