Aerodynamic Noise Reduction Device for pre-flight traffic aircraft

摘要

The arrangement has a hollow expansion body (4) arranged inside a rear profile curve and fixed to the curved profile surface of the slat (1). The expansion body is positioned in the space enclosed by the profile curve without additional restraints through connection to additional aerodynamic bodies. At least one controlled bleed air line is arranged partly in the cavity (5) in the slat and is connected to the expansion body.
