1. A rotorcraft, comprising:

  • a body;

    a wing coupled to the body;

    a power train coupled to at least one of the body or the wing and comprising a power source and a shaft in mechanical communication with the power source;

    a tiltrotor assembly pivotally coupled to the wing and in mechanical communication with the shaft, the tiltrotor assembly comprising;

    a hub in mechanical communication with the shaft;

    a rotor blade in mechanical communication with the hub and pivotable about an axis of rotation;

    a swashplate comprising a rotating portion and a non-rotating portion;

    a pitch link coupled to the rotating portion of the swashplate and in mechanical communication with the rotor blade; and

    an actuator coupled to the non-rotating portion of the swashplate and operable to reposition the swashplate from a first position to a second position such that the pitch links pivot the rotor blade from a deployed position to a folded position.
