An aircraft airfoil disclosed herein has a forward skin structure at least partially defining a leading edge of the airfoil and an aft skin structure at least partially defining a trailing edge of the airfoil. At least one of the forward skin structure and the aft skin structure is movable relative to the other of the forward skin structure and the aft skin structure between a closed position, in which at least one thrust fan positioned between the leading edge and the trailing edge is at least partially covered, and an open position, in which the at least one thrust fan is less covered than in the closed position.
