1. An engine for an aircraft, the engine comprising:
a rotating airfoil assembly including a rotation axis and a plurality of rotating airfoils configured to rotate about the rotation axis in a plane of rotation;
a torque producing system coupled to the rotating airfoil assembly and configured to rotate the rotating airfoil assembly about the rotation axis of the rotating airfoil assembly;
an engine support structure for supporting the torque producing system, the engine support structure including a forward strut and an aft strut, the forward strut and an aft strut being directly attached to each other, at least one of the forward strut or the aft strut being a movable strut that is movable relative to the other one of the forward strut or the aft strut in a forward direction and an aft direction, the engine support structure being connected to the torque producing system by a plurality of mounts, at least one mount of the plurality of mounts being attached to the movable strut to move with the movable strut;
at least one actuator operably connected to the movable strut to move the movable strut in the forward direction and the aft direction to rotate the torque producing system and change the plane of rotation of the plurality of rotating airfoils by rotating the rotating airfoil assembly together with the torque producing system; and
a controller configured to determine that the aircraft has an angle of attack and to operate the at least one actuator to rotate the torque producing system and change the plane of rotation of the plurality of rotating airfoils based on the angle of attack.
