1. A method of folding a wing, the method comprising:
connecting a first opening in a first fixed portion of a wing to a first opening in an unfixed portion of a wing at a first joint; aligning a first opening in a first link to a second opening in the fixed portion at a second joint, the second joint being located in the fixed portion and distinct from the unfixed portion; actuating a link actuator that engages the first link and causes the first link to rotate concentrically about the first opening of the first link and the second joint; connecting the first link to a second link via aligning a second opening of the first link with a first opening in the second link at a third joint located distinct from both the fixed portion and the unfixed portion; aligning and connecting a second opening in the second link to a second opening in the unfixed portion at a fourth joint, such that rotating the first link concentrically about the first opening of the first link and the second joint causes rotating the second link about a fourth joint and thereby moving the unfixed portion of the wing with respect to the fixed portion of the wing via rotating the unfixed portion of the wing concentrically about the first joint and the first opening of the unfixed portion; said method further comprising sensing a position of one of the first link and the second link via a group of sensors; and
a link actuator driving a torque tube having at least one toothed member, the toothed member fitting with teeth engaging the first link and causing the third joint to rotate about the second joint located in the first fixed portion of the wing,the toothed member being located between the first joint and the second joint. |
