The structural health monitoring (SHM) system being developed forthe Eurofighter Typhoon is resident on each aircraft and is integrated withinexisting aircraft and ground-based systems. The system will enable theoperators to accurately monitor fatigue life consumption, usage informationand significant structural events, thereby safeguarding the structuralintegrity of the aircraft. The information obtained can be used to planmaintenance actions effectively, and to manage the fleet fatigue lifeproactively (Hunt S R and Hebden I G, Eurofighter 2000 structural healthand usage monitoring: an integrated approach 2nd Joint NASA/FAA/DoD Conf.on Aging Aircraft (Williamsburg, VA, August 31-September 3 1998)).This paper gives an overview of the philosophy and techniques involved in thevalidation of the Eurofighter SHM system, together with some preliminaryresults.
