    • A method of stiffening a rib (19, 20) during the assembly of an aircraft wing is described. A stiffener panel (40, 41) is attached to a face of the rib (19, 20). The rib is aligned with one or more wing components with the stiffener panel (40, 41) attached. An assembly operation such as drilling (16) is performed with the rib aligned and the stiffener panel attached. The stiffener panel (40, 41) is removed from the rib after the assembly operation. The stiffener panel has a resilient external sealing ring which is mounted on a face of the panel and forms an external perimeter of a vacuum cavity; and at least one resilient internal sealing ring which is mounted on the panel (20, 21) within the perimeter defined by the external sealing ring and forms an internal perimeter of the vacuum cavity. The stiffener can be attached to the rib by a vacuum clamping force, the vacuum being sealed by the external and internal sealing rings. The internal sealing ring(s) seal any holes which are present in the rib. The stiffener (40, 41) can support the rib (20, 21) during alignment to give it the required flatness.
    • 描述了在飞行器机翼的组装期间加强肋(19,20)的方法。 加强板(40,41)附接到肋(19,20)的表面。 肋与一个或多个机翼部件对准,并且加强板(40,41)连接在一起。 执行诸如钻孔(16)的组装操作,其中肋对准并且加强板连接。 在组装操作之后,加强板(40,41)从肋上移除。 加强板具有弹性的外部密封环,其安装在面板的表面上并形成真空腔的外周; 以及至少一个弹性内部密封环,其安装在由外部密封环限定的周边内的面板(20,21)上并形成真空腔的内部周边。 加强件可以通过真空夹紧力连接到肋上,真空由外部和内部密封环密封。 内密封环密封肋中存在的任何孔。 加强件(40,41)可以在对准期间支撑肋(20,21),以使其成为所需的平整度。

    • An aircraft structure or wing extending from a root to a tip having the root arranged to be joined to an aircraft fuselage at a wing box 20. The structure has upper and lower covers with an aerodynamic outer surface and an inner surface. The structure also includes a plurality of stiffeners 8 and a plurality of ribs 13. The ribs include an inboard rib 10 and a plurality of further ribs between the inboard rib and the tip. Each of the stiffeners has a stiffener flange joined to the inner surface of the cover and a stiffener web extending away from the stiffener flange. One of the further ribs has a rib web and a plurality of rib feet. Each rib foot includes a first rib foot flange joined to the web of a respective one of the stiffeners, a second rib foot flange joined to the inner surface of the cover or to the flange of the respective one of the stiffeners and a rib foot web joined to the rib web. The joint between the first rib foot flange and the stiffener flange provides an efficient path for transmitting load from the cover into the rib web. Typically each first rib foot flange is joined to the stiffener web by a joint which can transmit load in shear from the stiffener web to the first rib foot flange.
