Abstract:
1. Leading edge mobile flap ( 16 ) for a main wing ( 4 ) of the wing system of an aircraft ( 1 ), said flap including an aerodynamic skin ( 18 ) that has a bird impact-sensitive frontal area ( 24 ), and a rear skin ( 28 ) extending between and intergral with a trailing edge ( 22 a ) of an upper surface portion ( 22 ) of the aerodynamic skin ( 18 ) and with a trailing edge ( 20 a ) of a lower surface portion ( 20 ) of this skin ( 18 ), said flap also comprising a plurality of ribs ( 32 , 34 , 40 ) spaced out along a leading edge longitudinal direction (X′), characterised in that the flap additionally includes, between two directly consecutive ribs, a single rigid bird trajectory-deflecting wall ( 42 ) anchored to the aerodynamic skin ( 18 ) and to the rear skin ( 28 ), this wall ( 42 ) being capable of deflecting the trajectory of a bird subsequent to it impacting against said impact area ( 24 ), and in that in a cross-section taken along any plane orthogonal to the leading edge longitudinal direction (X′), said rigid deflecting wall ( 42 ) forms with a geometric chord ( 26 ) of the flap an angle (α 1 ) with a value of less than 45°.
