Dual-rib morphing leading edge |
| 摘要 |
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 shapes. |

1. A mechanism for changing a shape of a flexible leading edge of an airfoil, comprising:
a first rib including a plurality of first rib segments, the first rib configured to move between a first folded shape and a first extended shape; a second rib including a plurality of second rib segments, the second rib configured to move between a second folded shape and a second extended shape; and one or more actuators 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 shapes wherein the one or more actuators are coupled to the first rib and the second rib and the one or more actuators are configured to move the second rib into the second extended shape while moving the first rib into the first folded shape. |
