    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: 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.
