Abstract:
Aero-engine blade-off event could cause serious malfunction and endanger flight safety, which is an important issue widely concerned for a long period. This paper presents a comprehensive review on the regulation requirements, the major research methods and status at home and abroad. Firstly, the relevant certification regulations and standards about aero-engine structure safety due to blade-off event were overviewed and the research gaps between the abroad and the domestic were compared. Then, the simulation and experimental methodologies on aero-engine supporting structures undertake abnormal load due to blade-off event were discussed as major issue. Finally, the safety certification verification technology system for aero-engine support structures during blade-off event was proposed.
