This report covers the design, analysis, manufacturing and testing done during Phase II, Detail Design, of the Advanced Metallic Air Vehicle Structure AMAVS program. The objectives of Phase II were to complete the detail design work for two configurations of a wing carrythrough structure for a movable-wing aircraft, to complete materials and component testing in support of the two configurations, to select one of the configurations for manufacture in Phase III and to continue design and manufacture of a fixture for full-scale testing of the carrythrough structure. Additional trade studies and design optimization studies were conducted in the early part of Phase II for the two configurations selected in Phase Ib Fail Safe Integral Lug FSIL and No-Box Box NBB. An updated baseline data package was received during Phase II and the configurations were revised to meet the modified baseline requirements. Material testing and component testing were completed. Beta annealed 6Al-4V and Beta C titanium and 10Ni steel HY180 were used in these tests. Some detail design work remains on the full-scale test fixture but manufacturing has started. Manufacture of the simulated fuselage structure has also begun. The NBB configuration which utilizes the outstanding fracture toughness and good crack growth characteristics of 10Ni steel has been selected for manufacture in Phase 3.
