Abstract : Secondary composite structure for civil and military transport aircraft have been successfully developed under the NASA Aircraft Energy Efficiency (ACEE) Program. The cost and weight benefits of such composite structures have been validated by the design, manufacture and test of several components and confidence in these applications has been achieved through interface with the FAA and the airlines. These programs are nearing completion and the aircraft manufacturers are beginning to incorporate composite versions of such structures in plans for future aircraft. While composites technology for secondary structures is now considered state-of-the-art, the major payoff will come with application of composites to primary structure, which comprises about 75 percent of transport structural weight. However, to reach this milestone, a comprehensive data base is needed to assure that both technical and financial risks are acceptable before incorporating these materials into safety-of-flight structure.
