Flow body for an aircraft for passive boundary layer suction

An aircraft having a fuselage and a flow body comprising:

• a flow surface exposed to an airstream during flight of the aircraft;
• at least one structural component attached to an interior of the flow surface;
• at least one perforated area comprising a plurality of openings extending through the flow surface;
• a manifold positioned interior to the flow surface in fluid communication with the openings and upstream of the at least one structural component;
• and
• at least one suction duct having a first end and a second end, the first end in fluid communication with the manifold and the second end placed exterior to the flow surface downstream of the at least one structural component, the at least one suction duct running on an exterior side of the flow surface,
• wherein the at least one suction duct comprises a suction opening facing away from the first end,
• wherein the suction opening is adapted for inducing a suction force into the at least one suction duct when the flow surface is exposed to an airstream during flight, thereby inducing a flow of air from through the openings to the suction opening.
