Abstract
A folding wing for an aircraft comprises a main wing portion having an upper surface and a lower surface and a wing tip portion having an upper surface and a lower surface and movable relative to the main wing portion about a folding axis. The wing further comprises a linkage mechanism connecting the wing tip portion to the main wing portion and an actuator coupled to the linkage system. Movement of the actuator causes the wing tip portion to move from a first position in which the wing tip portion extends in substantially the same plane as the main wing portion to a second position in which the wing tip portion is angled relative to the main wing portion.

A folding wing for an aircraft comprising:
- a main wing portion having an upper surface and a lower surface;
- a wing tip portion having an upper surface and a lower surface and movable relative to the main wing portion about a folding axis;
- a linkage mechanism connecting the wing tip portion to the main wing portion;
- and
- at least one actuator coupled to the linkage system such that movement of the at least one actuator causes the wing tip portion to move from a first position in which the wing tip portion extends in substantially the same plane as the main wing portion to a second position in which the wing tip portion is angled relative to the main wing portion, wherein the linkage mechanism is configured such that movement of the wing tip portion from the first position to the second position includes an initial phase of movement wherein the wing tip portion moves downwardly and away from the main wing portion and a further phase of movement wherein the wing tip portion moves rotates upwardly into the second position.
An aircraft, the aircraft including:
- a wing, the wing comprising:
- a main wing portion having an upper surface and a lower surface;
- a wing tip portion having an upper surface and a lower surface and movable relative to the main wing portion about a folding axis;
- a linkage mechanism connecting the wing tip portion to the main wing portion;
- and
- at least one actuator coupled to the linkage system such that movement of the at least one actuator causes the wing tip portion to move from a first position in which the wing tip portion extends in substantially the same plane as the main wing portion to a second position in which the wing tip portion is angled relative to the main wing portion, wherein the linkage mechanism is configured such that movement of the wing tip portion from the first position to the second position includes an initial phase of movement wherein the wing tip portion moves downwardly and away from the main wing portion and a further phase of movement wherein the wing tip portion moves rotates upwardly into the second position.
