A thrust vectoring mechanism to vector thrust and control discharge throat area includes four or more vanes mounted across the outlet of a nozzle in a cascade arrangement. The mechanism further includes a rod to control pivoting of each of the vanes that may be selectively rotated with one or more actuators. The rod includes threading. The vanes each include a drive member that is either toothed to engage the rod threading or defines a camming relationship with a coupling member threaded on the rod. The rod threading, drive members, and coupling members may be arranged to define different pivoting schedules for each of the vanes so that a generally constant throat area may be maintained over a given vector directional range of the vanes. The outlet may be generally rectangular in cross-section and a strut may be mounted across the outlet perpendicular to the pivot axes of the vanes to house the rod, drive members, and/or coupling members.
