Abstract
The U.S. Navy’s certification and qualification process for materials and structures is undertaken to ensure the flight safety and full mission capability of naval aviation weapon systems. A building-block process is practiced in which validated engineering data and concepts provide the foundation for continued technological development and innovation. For example, prior to developing material-property standards, the manufacturing process is frozen and fully characterized. The customer’s cost, schedule, and performance requirements must be carefully considered. Technologies are selected for immediate use or further R&D based upon a risk assessment that takes into account many factors, including technological maturity, lessons learned, the sponsor budget and schedule constraints, affordability, return on investment, and life-cycle cost impact. This paper explores the process that the navy uses to qualify its airframe alloys and structures.
