Abstract

Structural health monitoring (SHM) of airframes has developed over the decades to the stage where it is now incumbent for all fighter-type aircraft to be fitted with an airborne fatigue monitoring system. These systems typically collect operational data primarily for the calculation of the safe-life or the inspection interval of the airframe, thus helping to ensure that the structural certification limits for the aircraft are not exceeded. The requirement for SHM systems is explicitly stated in current military structural design standards. This article presents the reasons for requiring such systems and some general requirements for their implementation. The article draws upon the extensive experiences from Australian fatigue monitoring programs, and highlights some of the potential pitfalls in the systems and techniques.
