1. An aerospace vehicle system, comprising:

  • an airfoil having a leading edge;

    a first flow body fixedly coupled to the airfoil to form at least one gap between the leading edge of the airfoil and the first flow body; and

    a second flow body having a recess, an upper trailing edge, and a lower trailing edge, the second flow body being movably coupled to the airfoil to move between;

    a retracted position wherein the second flow body is positioned to at least approximately aerodynamically seal the at least one gap, and wherein the first flow body is located in the recess, the upper trailing edge is positioned proximate to the leading edge of the airfoil to at least approximately aerodynamically seal with the airfoil, and the lower trailing edge is positioned proximate to the leading edge of the airfoil to at least approximately aerodynamically seal with the airfoil; and

    an extended position where the second flow body is positioned to allow fluid flow through the at least one gap.
