The objective of the project will be to address certification and continued airworthiness issues arising from the use of emerging metallic materials and construction methods (new aluminum alloys--e.g., aluminum lithium; new production processes--e.g., friction stir welding; advanced metallic hybrids, Glare, bonded structure) increasingly being used for aircraft structures by development of a 10 year roadmap for the research and development required to assure future airworthiness of these advanced structural materials. This proposal will provide the Federal Aviation Administration (FAA) with data collected from various sources to understand the durability and damage tolerance performance of these emerging technologies, and determine the applicability of existing regulations and regulatory guidance material. The approach of this proposal will be to outline a roadmap to leverage existing FAA resources with those of industry, to ensure safe implementation of emerging technologies in aircraft products. |
