Title (EN) FLAPERON SYSTEM FOR TILT ROTOR WINGS
(FR) SYSTEME DE VOLET ET D'AILERON POUR AILES DE ROTOR INCLINABLE
Abstract:
(EN) The present invention provides an aircraft wing (10) having a main portion (20) with a trailing edge (20b) and a movable flaperon (22) hingedly secured at the trailing edge. A movable flaperon seal (40) is hingedly attached at its leading edge to the trailing edge of the main portion of the wing. Interconnecting structure is provided between the main portion of the wing and the flaperon seal. Such structure is operable to pivot the seal flap such that the opening between the trailing edge of the main wing portion (20b) and the leading edge of said movable flap (22a) on the upper surface is selectively closed by the movable flap at predetermined angular positions of the movable flap.
(FR) Aile (10) d'avion comportant une partie principale (20) dotée d'un bord de fuite (20b) et d'un volet-aileron mobile (22) fixé de manière articulée au bord de fuite. Un joint (40) de volet-aileron mobile est fixé de manière articulée au niveau de son bord d'attaque, au bord de fuite de la partie principale de l'aile. On a prévu une structure d'interconnexion entre la partie principale de l'aile et le joint du volet-aileron. Ladite structure permet de pivoter le volet à joint de sorte que l'ouverture entre le bord de fuite de la partie principale (20b) de l'aile et le bord d'attaque dudit volet mobile (22a) se trouvant sur la surface supérieure, est fermée sélectivement par le volet mobile, à des positions angulaires prédéterminées de ce dernier.
