An aircraft structure comprising: a rear spar; and a composite cover attached to the rear spar and having an overhanging portion extending to its rear. The overhanging portion of the cover comprises one or more ramps along which the thickness of the cover reduces. A second cover is attached to the rear spar and overhangs to its rear. A hinge rib is attached to one or both of the covers, and an aerodynamic control element such as an aileron, rudder or elevator is pivotally mounted to the hinge rib.

Trailing edge aircraft structure with overhanging cover

FIELD: aeronautical engineering; swept wings of medium-capacity and heavy aeroplanes whose landing gear wing legs are retracted into trailing-edge assembly and in fuselage well. SUBSTANCE: trailing-edge assembly is additionally provided with beam 12, under-wing beam 5 secured on wing torsion box 1 under tail boom inside flap mechanism fairing 4 whose attachment units are mounted on cantilever formed by tail boom and under-wing beam. Articulated attachment unit of landing gear beam and tail boom is hinged to one end of additional beam 12 which is connected in its turn with wing torsion box. Bell crank 8 connecting landing gear beam 6 with fuselage 7 is articulated to side strut 10 of landing gear. Attachment of panels 14 with wing torsion box 1 is of floating construction. EFFECT: reduced mass of wing and increased service life of wing structure due to reduction and redistribution of load exerted on wing torsion box by attachment units of landing gear. 6 dwg
