Wing for an aircraft

A wing for an aircraft, comprising:

• a main wing, and
• a slat assembly comprising:
• a slat, and
• at least one connection assembly movably connecting the slat to the main wing, such that the slat is movable between a retracted position and at least one extended position,
• wherein the at least one connection assembly comprises an elongate slat track that extends along a track longitudinal axis between a front end and a rear end and has an intermediate portion between the front and rear ends,
• wherein the front end of the slat track is mounted to the slat,
• wherein the rear end of the slat track, or the intermediate portion of the slat track, or both are mounted to the main wing by a roller or slide bearing such that the slat track is movable along the track longitudinal axis,
• wherein the connection assembly comprises a drive unit configured for driving the slat track for movement along the track longitudinal axis,
• wherein the drive unit comprises a rotary actuator mounted to the main wing and having at least one drive arm rotatably driven about a rotation axis and drivingly engaging the slat track, and,
• wherein one of the at least one drive arm and the slat track comprises at least one groove and the other one of the drive aim and the slat track comprises at least one spigot drivingly engaging the at least one groove,
• wherein the slat track is movable along a straight path or is movable along a curved path having an axis of rotation spaced from the rotation axis of the at least one drive arm.

A slat assembly for a wing of an aircraft, the slat assembly comprising

• a slat, and
• at least one connection assembly for movably connecting the slat to a main wing of the aircraft, the at least one connection assembly comprising:
• an elongate slat track that extends along a track longitudinal axis between a front end and a rear end and has an intermediate portion between the front and rear ends,
• wherein the front end of the slat track is configured to be mounted to the slat,
• wherein the rear end of the slat track, or the intermediate portion of the slat track, or both are configured to be mounted to the main wing by a roller or slide bearing such that the slat track is movable along the track longitudinal axis,
• wherein the at least one connection assembly comprises a drive unit configured for driving the slat track for movement along the track longitudinal axis,
• wherein the drive unit comprises a rotary actuator mounted to the main wing and having at least one drive arm rotatably driven about a rotation axis and drivingly engaging the slat track,
• wherein one of the at least one drive arm and the slat track comprises at least one groove and the other one of the at least one drive aim and the slat track comprises at least one spigot drivingly engaging the at least one groove, and
• wherein rotation of the at least one drive arm imparts movement to each of the at least one spigot and the at least one groove.
