Abstract:

This program selects, designs, fabricates, and evaluates SPF Al-Li airframe parts using advanced joining technology it also screens and evaluates SPF Al-Li alloys for application to candidate parts. Factors used in part selection include supportability, technical risk, and required development. A design trade study modifies and improves the advanced SPF Al-Li candidate parts by implementing efficient design concepts and advanced joining methods. Design and joining methods are evaluated using material from the same lots used for material evaluation. Demonstration parts and the required tooling are fabricated using criteria generated from producibility evaluations. Finally, the demonstration parts are subjected to verification testing as prescribed in the test plan.
