FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to aircraft leading edge. Leading edge extended by airfoil 26 whereon aerodynamic flow flows and air outlets 30 are located In two lines parallel with leading edge 22 and with displacement in two sequential lines 32. Leading edge comprises insert 36 fitted between walls that form airfoil 26. Note here that insert 36 comprises, on one side, pouter surface 38 extending airfoil 26, first incline surface 40 in contact with first wall and second inclined surface 42 in contact second wall to make said airfoil 26. On opposite side, it comprises recesses and/or ledges made level with inclined surfaces 40, 42 to alternate from one side to another to allow air passage from both sides of airfoil 26.
EFFECT: improved aerodynamics of aircraft.
