FIELD: transport. ^ SUBSTANCE: invention relates to aircraft engineering. Wing control surface 1 comprises flap 4 on wing tailing edge that runs along wing span and can be turned into different positions, sealing flap 5 arranged at top side between wing 1 and flap 4, and vent flap 5 arranged on reverse side between wing 1 and flap 4 to turn thereabout. Flap 4 can be turned through position directions downward and through negative directions upward. Positions of flap turn lies in the range of negative and minor positive magnitudes of position. Top side of wing surface is covered by sealing flap 7, while reverse side is covered by vent flap 5. To increase lift, turn of flap 4 varies between minor positive magnitudes and larger positive magnitudes. Vent flap 5 releases airflow from wing reverse side to top surface of flap 4. Sealing flap 6 is removed to allow the gap to air release from top surface of flap 4. ^ EFFECT: reduced mechanical loads and weight. ^ 30 cl, 7 dwg |
