ABSTRACT:
An exhaust nozzle includes a plurality of circumferentially spaced apart exhaust flaps, and a plurality of scissor linkages joined to respective ones thereof. Each linkage includes a frame pivotally joined to a respective one of the flaps. A carriage is slidably mounted to the frame. A pair of circumferentially oppositely extending side links are pivotally joined at one end to the carriage, and pivotally joined at opposite ends to corresponding side links to form an interconnected ring thereof. A pair of circumferentially oppositely extending equalizer links are pivotally joined at one end to the frame, and pivotally joined at opposite ends to corresponding ones of the side links to maintain coordinated angular position of the side links pivotable on the carriage, and in turn maintain circumferential spacing between adjacent ones of the flaps.
