FIELD: aviation.
SUBSTANCE: proposed device is movably articulated to may the wing and is extended from it. Inner section of slat has concave bend of profile aligned with outer contour of main wing; this bend is made in form of rounded-off adapter lengthwise the slat. Lower edge of slat is provided with separating surface at inlet of concave bend of profile and/or upper edge of slat is provided with separating surface at inlet of concave bend of profile; this separating surface consists of several brush hairs distributed along length of slat and arranged in one row.
EFFECT: reduction of aerodynamic noise on passenger aircraft slats which is induced during takeoff and landing of aircraft by flow of air through slat profile.
