Classification: CPC B | IPC B

Claim 9:
10. An aircraft comprising:
a fuselage; and
a wing coupled to the fuselage, wherein the wing comprises:
a main aerodynamic body having a leading edge and a trailing edge opposite the leading edge;
a flight control surface pivotably connected to the main aerodynamic body at an axis, wherein the axis is near the trailing edge of the main aerodynamic body; and
a rotating body coupled to the flight control surface, wherein:
the rotating body is rotatable relative to the flight control surface between a stowed position and a deployed position while the flight control surface is stationary relative to the main aerodynamic body, wherein:
rotation of the rotating body defines a gap between main aerodynamic body and the rotating body;
the rotating body is rotated toward the main aerodynamic body while in the stowed position to close the gap;
the rotating body is rotated away from the main aerodynamic body while in the deployed position to widen the gap; and
the gap adjusts an airflow flowing between the main aerodynamic body and the flight control surface.
