Acoustic Emission Monitoring in the course of Laboratory Fatigue Test of All-metal Aircraft Structure

Original language description

All-metal aircraft structure was inspected by acoustic emission method in the course of laboratory fatigue test. The critical point of Al-alloy flange was hidden by another steel part near the wing attachment. Because of customer specification, it was not possible to demount the row of bolted joints for inspection. The detection of fatigue crack as soon as possible was emphasised, due to later possibility of consideration the structure as damage tolerance. Structure conception and material differences did not allow inspections by traditional method of non-destructive testing, which required the direct access to the critical point. Acoustic emission sensors were placed along the spar flange and emission sources are localized linearly. The fatigue crackdetection was complicated by presence of many sources not related to fatigue, such as buckling and releasing of riveted and bolted joints, and elastic wave transmitting through the complex thin-plated structure.

Monitorování akustické emise při laboratorní únavové zkoušce celokovové letecké konstrukce

Czech description

Dokumentováno je použití metody akustické emise při laboratorní únavové zkoušce celokovového křídla sportovního letounu. Monitorována byla kritická oblast pásnice hlavního nosníku v místě závěsu křídla. Spolehlivost metody byla současně ověřována při sledování odezvy únavových poškození kostry trupu.
