    摘要： A method to superplastic form sandwich structures is provided. A series of worksheets are joined together at selected locations through the use of partial penetration welding. The worksheets are subsequently superplastic formed in order to form a sandwich structure. The method allows a different number of worksheets to be used at different points throughout the sandwich structure. This results in a sandwich structure with a different internal reinforcement at different locations in the sandwich structure. In the preferred embodiment, a wing is fabricated from a series of worksheets partial penetration welded together using a laser. The worksheets are superplastic formed to producing a wing with a different internal reinforcement at two or more locations in the wing. The wing includes a pair of double thickness skins that define a major portion of aerodynamically smooth outer surface of the airfoil. Each skin is formed from at least two sheets of superplastically formed material that are joined by diffusion bonding. The internal reinforcement extends between the surface's interior surfaces of the skins and are welded to the skins by wave welds. The webs of the internal reinforcement extend between the skins diagonally and each web is formed of a single sheet of superplastically formed material.

    摘要翻译： 提供了一种超塑性夹层结构的方法。 一系列工作表通过部分穿透焊接在选定的位置连接在一起。 工件表随后被形成为超塑性以形成夹层结构。 该方法允许在整个夹层结构中的不同点使用不同数量的工作表。 这导致在夹层结构中在不同位置处具有不同内部加强件的夹层结构。 在优选实施例中，翼由使用激光部分穿透焊接在一起的一系列工作表制成。 工作表是超塑性的，用于在翼中的两个或更多个位置处产生具有不同内部加强件的翼。 机翼包括一对双层厚皮，其限定了翼型的空气动力学平滑的外表面的主要部分。 每个皮肤由通过扩散粘合连接的至少两片超塑性材料形成。 内部加强件在表面的表面的内表面之间延伸并且通过波纹焊接到表皮上。 内部加强筋的腹板在对角线之间延伸，每个腹板由单层超塑性材料形成。

    摘要： An apparatus and method for forming a stringer are provided. The stringer generally includes a web having a desired corrugated configuration and first and second flanges welded to opposite edges of the web. The apparatus includes a support structure, a strongback that is supported by the support structure, and a plurality of dies that are adjustable relative to the strongback. The strongback defines a corrugated contour surface corresponding to the desired corrugated configuration of the web. The dies define corresponding forming surfaces and are configured to be advanced toward the strongback to thereby form the web to the desired corrugated configuration between the contour surface of the strongback and the forming surfaces of the dies. Further, the apparatus can receive the flanges of the stringer in a predetermined configuration with the web so that the flanges can be welded to the web while the web is supported by the strongback and dies in the desired corrugated configuration.
