1. A vehicle with a morphing airfoil comprising:
a plurality of actuator ribs configured to move under an actuation force;
a plurality of compliant structural support ribs extending from a main spar to a trailing edge of the airfoil positioned between the actuator ribs;
a non-stretchable flexible skin completely covering the actuator ribs and the non-actuated support structure formed in a shape of an airfoil; and
wherein the non-stretchable flexible skin is slidably attached to the compliant structural support ribs and drives a shape change of the compliant structural support ribs when the camber of the airfoil is changed with the actuator ribs.
