A wing has a changeable profile, and extends in a wing chord direction and
perpendicularly thereto in a wingspan direction. The wing has a first
cover skin and a second cover skin spaced apart from one another with
spars therebetween. The wing includes a leading edge region and a
trailing edge region opposite one another in the wing chord direction,
and a wing tip region at the end of the wing in the wingspan direction.
The wing further includes a flexible region that connects the wing tip
region to the rest of the wing, and that is adapted to vary the profile
of the wing in a direction that includes a component in the wing chord
direction and a component in the wingspan direction.
