초록

A mechanism for changing a shape of a leading edge of an airfoil may include a first rib and a second rib. The first rib may include a plurality of first rib segments. The first rib may move between a first folded shape and a first extended shape. The second rib may include a plurality of second rib segments. The second rib may move between a second folded shape and a second extended shape. An actuator may be coupled to the first rib, the second rib, or both, to move the first rib, the second rib, or both, between their respective folded and extended sha...
