VERTICAL TAIL UNIT FOR FLOW CONTROL

Disclosed is a vertical tail unit (7) for flow control, comprising an outer skin (13) in contact with an ambient air flow (21), wherein the outer skin (13) extends between a leading edge (23) and a trailing edge (25) with two opposite lateral sides (27a, 27b), and surrounds an interior space (29), and wherein the outer skin (13) comprises a porous section (31) in the area of the leading edge (23), a pressure chamber (15) arranged in the interior space (29), wherein the pressure chamber (15) is fluidly connected to the porous section (31), an air inlet (17) provided in the outer skin (13) and fluidly connected to the pressure chamber (15), and an air outlet (19) provided in the outer skin (13) and fluidly connected to the pressure chamber (15). The object, to provide a vertical tail unit with reduced drag an increased efficiency, is achieved in that the air inlet (17) is formed as an opening (35) that is arranged in one lateral side (27a) of the outer skin (13) and that is flush with the outer skin (13).
