The Fatigue in Aircraft Corrosion Testing (FACT) Programme
Abstract
Failure by fatigue and degradation by corrosion continue to be major considerations aircraft design. Environmental effects influence both initiation and propagation of fatigue cracks, and dynamic loading may cause more rapid deterioration of corrosion protection systems. Therefore the conjoint action of dynamic loading and environmental attack, i.e., corrosion fatigue, requires special attention. Many corrosion fatigue tests have been done on aluminum alloys. However, few included critical structural details like joints, under realistic cyclic load histories and in service-like environments. Even fewer used practical corrosion protection systems. These aspects are specifically addressed by the FACT programme and its predecessor CFCTP programme. The results provide a significant contribution to the understanding of aircraft corrosion fatigue and should encourage further investigation in this difficult and challenging area of aerospace technology.
