Abstract

A flow body (34) of an aircraft comprises a flow surface (46) exposed to an airstream during flight of the aircraft, at least one structural component (38) attached to an interior of the flow surface (46), at least one perforated area (12) comprising a plurality of openings extending through the flow surface (46), a manifold (36) positioned interior to the flow surface (46) in fluid communication with the openings and upstream of the at least one structural component (38), and at least one suction duct having a first end and a second end, the first end being in fluid communication with the manifold and the second end placed exterior to the flow surface (46) downstream of the at least one structural component (38). The at least one suction duct (42, 44) comprises a suction opening (56, 58) facing away from the first end. Further, the suction opening is adapted for inducing a suction force into the at least one suction duct (42, 44) when the flow surface (46) is exposed to an airstream during flight, thereby inducing a flow of air from through the openings to the suction opening (56, 58).
