Abstract
A method and system are used to calibrate a plurality of actuators joined to an actuation ring in a control system for vectoring exhaust flaps in a vectoring nozzle. The actuators include output rods which are positioned to respective first positions at which output stroke is measured. The actuators are repositioned to different second positions, and the output stroke thereof is again measured. The stroke measurement for each of the actuators is calibrated to effect a common linear response between the first and second measurement positions. The calibrated actuators ensure coordinated linear actuation thereof as the output rods are positioned between their minimum and maximum extensions.
