1. A jet engine system, comprising:

  • at least one engine including;

    a synchronization ring configured to circumferentially rotate;

    an inner housing that supports the synchronization ring;

    an actuation system including;

    first and second ring gearboxes coupled to the inner housing and configured to rotate the synchronization ring;

    an actuator having a first gearbox configured to generate a first rotational output and a second actuator gearbox configured to generate a second rotational output;

    a first drive shaft having a first shaft end rotatably coupled to the first actuator gearbox and a second shaft end rotatably coupled to the first ring gear box; and

    a second drive shaft having a first shaft end rotatably coupled to the second actuator gearbox and the second shaft end rotatably coupled to the second ring gear box,wherein the actuator is configured to simultaneously control the first and second actuator gearboxes such that the first and second rotational outputs are simultaneously transferred to the first and second ring gearboxes, respectively, to circumferentially rotate the synchronization ring.
