Abstract : The patent relates to a control system for a flexible seal movable nozzle in which movement of the nozzle is effected by pairs of hydraulic actuators, one pair in the pitch plane and one pair in the yaw plane. Each of the paired actuators is connected to identical linear variable differential transducers of potentiometers which measure actuator displacements to provide a signal as loop feedback.
