Patent number: 8329312Abstract: A superplastically formed structural assembly is provided, as is an associated preform and method for forming such an assembly. The assembly includes a skin member and a support member that are joined to define a space between the members and between the joints. The assembly can be produced by joining the members in a flat configuration, and then forming the resulting preform to a predetermined shape of the structural assembly. The support member defines at least one aperture in communication with the space between the members. Thus, the skin member can be formed by delivering a pressurized fluid through the support member to the skin member, e.g., to superplastically form the skin member against a die that defines a contour surface corresponding in shape to the predetermined configuration of the assembly. The support member can extend in a substantially direct configuration between opposing portions of the skin member.Type: GrantFiled: June 27, 2011Date of Patent: December 11, 2012Assignee: The Boeing CompanyInventors: Daniel G. Sanders, David W. Foutch, Jeff D. Will, Luis Leon, Gregory L. Ramsey, Garry A. Booker

Patent number: 8328075Abstract: The invention provides methods of superplastic forming and diffusion bonding and a gas inlet tube that facilitates the methods which produce structures that are substantially mark off free. Methods include disposing a sealed pack into a die having a patterned surface and an opposite surface; applying a first pressure within the die around an outside of the pack; applying a second pressure within the pack, the second pressure exceeding the first pressure; and forming the pack by superplastic deformation into a diffusion-bonded structure. Further, a gas inlet tube is provided having an inner tube and an outer tube, where the outer tube is weldable to the pack in a gas tight seal.Type: GrantFiled: March 30, 2006Date of Patent: December 11, 2012Assignee: The Boeing CompanyInventors: Daniel G.
