A full-scale fatigue test was completed in August 1974 on a Mirage 1110 starboard wing utilising a loading spectrum as specified by the Royal Australian Air Force RAAF. To satisfy a variety of RAAF missions, twelve 12 servo-hydraulic actuators situated at critical locations on the wing reproduced the measured flight strains. The fatigue loading flight-by-flight sequence was derived from fatigue meter data that was obtained from the Mirage fleet and from continuous records from an instrumented Mirage in the squadron service. The conduct and results of this innovative test are summarised here.
