Description:
FIELD: aviation.SUBSTANCE: aircraft wing mounting device comprises connection assemblies of the front and rear wing panels spars to the fuselage central part frames. Connection assemblies of the front wing panels spar to the fuselage frame is made double-joint in the transverse plane with an intermediate and includes a fuselage frame section, which faces the wing panel and is provided with front and rear braces, which form a cavity for the intermediate and the front spar bracket tip. Front and rear braces of the frame are provided with an opening for the installation of the fastening element connecting the intermediate with the wing panel front spar bracket tip. The fuselage spar is made with a hole for the wing panel front spar bracket. The front and rear frame braces are also connected to the intermediate by a fastening element mounted along thedouble-hinged assembly axis.EFFECT: reduced weight of the aircraft by reducing the load on the fuselage of the wing panel bending deformation.6 cl, 7 dwg Изобретение относится к конструктивным элементам летательных аппаратов. Устройство крепления крыла летательного аппарата содержит узлы присоединения передних и задних лонжеронов консолей крыла к шпангоутам центральной части фюзеляжа. Узел присоединения переднего лонжерона консолей крыла к шпангоуту фюзеляжа выполнен двухшарнирным в поперечной плоскости с промежуточным звеном и включает участок шпангоута фюзеляжа, который обращен к консоли крыла и выполнен с передней и задней стойками, которые формируют полость под промежуточное звено и наконечник кронштейна переднего лонжерона. Передняя и задняя стойки шпангоута выполнены с отверстием под установку крепежного элемента, соединяющего промежуточное звено с наконечником кронштейна переднего лонжерона консоли крыла. Лонжерон фюзеляжа выполнен с отверстием под кронштейн переднего лонжерона консоли крыла. Передняя и задняя стойки шпангоута также соединены с промежуточным звеном посредством крепежного элемента, установленного вдоль оси двухшарнирного узла. Изобретение направлено на снижение веса летательного аппарата за счет уменьшения нагрузки на фюзеляж от изгибной деформации консолей крыла. 5 з.п. ф-лы, 7 ил.
