Auxiliary airfoil for aircraft main wings

摘要

A separating surface (6) is arranged on an additional airfoil for an aircraft main wing (3). The separating surface (6) is hinged on the main wing (3) and can be extended. The separating surface (6) extends in the direction of the main wing (3) and is arranged along a separation flow line (9) between a vortex flow region (8) and a slat cove flow (7) of the air flowing between the additional airfoil and the main wing (3).
