A thrust vectoring exhaust nozzle (10) includes a plurality of flaps (16-22) and seals (24-28) positioned by a unison ring (52) and flap links (54-60).

Axisymmetric nozzle with gimbled unison ring

An axisymmetric thrust vectoring exhaust nozzle includes a plurality of divergent flaps (30) each supported at the upstream end by a universal joint (32) and at the downstream end by a load link (34) connected to a unison ring (36) positioned by actuators (45).

Thrust vectoring exhaust nozzle

A yaw and pitch thrust vectoring exhaust nozzle includes a spherical collar, and two surrounding clam shells hinged to a gimbal ring and pivotal about an axis perpendicular to the clam shell hinge axis. The clam shells define a variable area nozzle throat (42) which can be selectively directed vertically by rotation of the clam shells about the hinge axis (38), or horizontally by rotation of the clam shells and gimbal ring about the pivot axis (30), thereby biasing the nozzle exhaust flow vector. Divergent flaps (44, 46) further direct the exhaust downstream of the nozzle throat (42). '
