ABSTRACT:
Disclosed is a process for fabrication and assembly of airframes and airframe components utilizing the principles of diffusion bonding and superplastic forming. A preform blank or blank sheet of material capable of being superplastically formed and diffusion bonded is attached to an airframe body or casing by diffusion bonding and superplastically deformed to form a structural airframe component. The superplastically formed structural component may be diffusion bonded to other airframe components and the superplastic forming and diffusion bonding steps may be performed simultaneously or successively to progressively fabricate and assembly an airframe having unique structural geometries and characteristics without conventional machining or welding of component parts.
