The Air Vehicles Research Section of DCIEM is responsible for the delivery of all R&D that directly concerns the CF aircraft in the areas of aircraft structures and materials, aeropropulsion, aerodynamics and flight mechanics. The requirement to retain and maintain CF fleets for extended periods of time beyond their normal lives has put most of these aircraft in the "aging" category. This has required the development of novel approaches and concepts in order to reduce the costs involved in this tong-timer maintenance effort. This paper will describe several of these recent approaches that are currently under development from the advanced materials perspective. These will include: - a methodology for the in-situ application of a novel heat treatment for 7075-T6 aluminum alloys and the application of a thermal spray coating in order to reduce the incidence of stress corrosion cracking of major aircraft structural components; - the development of advanced coatings for the replacement of current coatings that involve toxic application processes, such as chromium and cadmium; - the development of novel techniques for nondestructive evaluation, particularly for the detection of hidden corrosion; - the application of "smart structures" technology for the development of an instrumented composite patch for metallic aircraft structure.
