The fairing arrangement (28) comprises a first fairing portion (32) on a wing (10) and a second fairing portion (34) on an aileron (12) which is mounted on and angularly displaceable with respect to the wing. The fairing arrangement protrudes (28) outwardly of the aerodynamic profile S of the wing to cover part of an actuating device for the aileron. Parts of the first and second fairing portions (32, 34) are arranged to overlap each other to form a seal (45), one of said overlap parts defines an oblique sealing surface (44) which lies substantially in the direction of the path of movement of the aileron (12) over the normal operational range of movement of the aileron. The overlap parts (32, 34) of the first and second fairing portions overlap each other over a normal operational range of the aileron (12) to form the seal (45) but do not overlap to form a seal over the remainder of the range in one of the directions of movement of the control surface.

L'invention concerne un arrangement de carénage (28) comprenant une première partie de carénage (32) disposée sur une aile (10) et une seconde partie de carénage (34) disposée sur un aileron (12) monté sur l'aile et doté d'une mobilité angulaire par rapport à l'aile. Cet arrangement de carénage dépasse (28) du profil aérodynamique S de l'aile, de sorte qu'il recouvre une partie d'un dispositif d'actionnement de l'aileron. Des parties de la première et de la seconde parties de carénage (32, 34) sont arrangées de sorte qu'elles se chevauchent pour former un scellement (45) et l'une d'entre elles définit une surface de scellement oblique (44) sensiblement orientée dans la direction du mouvement de l'aileron (12) sur la portée opérationnelle normale du mouvement de l'aileron. Ces parties chevauchantes (32, 34) de la première et de la seconde parties de carénage se chevauchent sur la portée opérationnelle normale de l'aileron (12) afin de former un scellement (45) mais ne se chevauchent pas afin de former un scellement sur le reste de la portée dans l'une des directions du mouvement de la surface de commande.
