A nozzle load transferring means is provided for transferring at least a portion of the thrust load of a gas turbine engine thrust vectoring nozzle to a relatively stationary portion of the engine using a track and track follower disposed between a stationary portion of the engine and the vectorable flap respectively so as to transfer the thrust loads developed on vectorable flap to the track follower and then to the track. The preferred embodiment of the invention includes a convergent/divergent axisymmetric vectoring nozzle having a plurality of universally pivotable divergent flaps wherein the track is mounted to the engine case and has a spherical following surface with a center of curvature on the nozzles center-line. A divergent flap actuating ring is pivotably received within the track by a plurality of track followers mounted to the actuating ring and in roller bearing engaging relationship with the track surface. The actuating ring is operably connected to the divergent flaps so as to pivot the flaps for thrust vectoring.
