Abstract
An actuation unit (15) for actuating a foldable wing tip portion (9) of a wing (3) for an aircraft (1). The actuation unit (15) includes a track (25) configured to be mounted to a fixed wing (5), a carriage (27) configured to engage the track (25) for guided movement along the track (25), and configured to be coupled to a drive unit (31) for driving the carriage (27) along the track (25), and a link (29) configured to be coupled to the carriage (27) and configured to be coupled to a foldable wing tip portion (9).
Claims17
An actuation unit for actuating a foldable wing tip portion to pivot about a hinge axis of a hinge connecting the foldable wing tip portion to a fixed wing portion of a wing for an aircraft, the actuation unit comprising:
- a track configured to be mounted to the fixed wing portion;
- a carriage configured to engage the track for guided movement along the track, and configured to be coupled to a drive unit configured to drive the carriage along the track, and
- a link configured to be coupled to the carriage and configured to be coupled to the foldable wing tip portion,
- wherein the link is offset from the hinge in a direction perpendicular to the hinge axis such that an axis of the link does not extend through the hinge.
A wing for an aircraft comprising
- a fixed wing portion,
- a foldable wing tip portion mounted to the fixed wing portion via hinges rotatable about a hinge axis, and
- an actuation unit including:
- a track mounted to the fixed wing portion;
- a carriage engaging the track to move along the track,
- a drive unit mounted to the fixed wing portion and configured to drive the carriage along the track, and
- a link coupled to the carriage and to the foldable wing tip portion at a position spaced apart from the hinge axis in a direction opposite to the direction in which the foldable wing tip portion is moved to the folded position.
A wing of an aircraft, the wing comprising
- a fixed wing including a root attached to a fuselage of the aircraft and an end opposite to the root;
- a foldable wing tip mounted to the end of the fixed wing via hinges rotatable about a hinge axis, and
- an actuation unit including:
- a track mounted to the fixed wing;
- a carriage configured to engage the track and move along the track;
- a drive unit mounted to the fixed wing and configured drive the carriage along the track, and
- a link coupled to the carriage and to the foldable wing tip such that movement of the link and carriage moves the foldable wing tip between an extended position and an folded position, wherein a coupling between the link and the foldable wing tip is spaced apart from the hinges, and the carriage and link move along a direction perpendicular to the hinge axis.
