Abstract

A joint for coupling a wing tip to a wing base includes a linking member that extends from a first end to a second end. The linking member first end is coupleable to the wing base, and the linking member second end is coupleable to the wing tip. The linking member may be curved and may extend for a fixed distance between the wing tip and the wing base. The linking member defines first second hinge lines that are substantially parallel. The joint also includes at least two actuators. A first end of each actuator is coupled to the linking member, and a second end of each actuator is coupleable to one of the wing base and the wing tip. The actuators are operable to rotate the wing tip about the first and second hinge lines between a first orientation and a second orientation relative to the wing base.
