FIELD: transport.
SUBSTANCE: invention relates to aircraft engineering, particularly, to joint between engine pylon hinged structural beam and wing torsion box. Said joint comprises front and rear fittings of attachment of said beam to front and rear wing torsion box frames with rib arranged there between. Front assembly is composed by vertical pivot extending through pylon structural carcass. Said pivot has two locating seat for interaction with mating locating surfaces of the top and bottom panels of structural beam and is secured over two other locating surfaces at top and bottom lugs of the front frame. Coupling element is arranged inside said pivot. Rear attachment assembly is arranged at rear frame bottom part and composed of at least one clamp located in vertical plane and connected with rear part of hinged structural beam and with rear wing torsion box spar.
EFFECT: simplified design, higher reliability, longer life.
