Abstract: A mechanism for moving a slat of an aircraft wing of an aircraft includes a rib, an arm, a first bar and a second bar. The arm is disposed generally parallel with the rib. The rib, the arm and the first and second bars cooperate to form a four-bar linkage. The first and second bars rotatable about connection points in a negative pitch rotational direction to dispose the arm in an extended position, and in a positive pitch rotational direction to dispose the arm in a default position.

Abstract: An aircraft includes a wing and a leading-edge aerodynamic surface coupled to the wing. An actuator is disposed within the wing and coupled to the leading-edge aerodynamic surface via a linkage system. Two or more hinge systems are coupled to the leading-edge aerodynamic surface and configured to rotate about a fixed axis internal to the wing to move the leading-edge aerodynamic surface between a retracted position and a drooped position.

Abstract: A system and a method include a crank pivotally coupled to a bracket of a main body of a wing of an aircraft. A drive link is pivotally coupled to the crank. A flap link is pivotally coupled to a carrier beam extending from a flap moveably coupled to the main body of the wing. A rocker bracket is pivotally coupled to the flap link and the drive link.

Abstract: A mechanism for moving an aircraft wing slat between a retracted position and a deployed position includes a rib, an arm, a first bar and a second bar. The arm is disposed generally parallel with the rib and is configured for attachment with the wing slat. The rib, the arm and the first and second bars cooperate to form a four-bar linkage which is rotatable about connection points in a negative pitch rotational direction to dispose the arm in the deployed position, and in a positive pitch rotational direction to disposing the arm in the retracted position. The mechanism includes additional structures for maintaining the arm in the deployed position, including a magnetic extend stop and a standoff, an arm lobe and a cross-bolt, and a bar lobe and a linear member.
