A foldable aerodynamic structure has a second region 11 movable relative to, and connected to a first region 12 by a slew bearing; the slew bearing 6 has a second surface 16, which rotates relative to a first surface 15 formed by a component which is at least partially integrated with a load-bearing part 122, such that component loads are transmitted to the load-bearing part. Preferably, the first region 12 is a root section of an aircraft wing and the second region 11 is a wing tip section. The component may be integrally formed with the first load-bearing part (fig.2,25,222). Alternatively, the component may be a separate ring (fig.6,47), which is partially received in a semi-circular or v-shaped recess in the load-bearing part (fig.4a). The ring may have segments which can be separated, with an anchor (fig.6,61) between segments used to prevent rotation. The second bearing surface may have upper and lower parts (fig.4b,481,482), both attached to load-bearing parts in each region.
