Abstract: Development status and trends of aero-engine containment case were reviewed in respect of the containment capability definition,case material,design concept and method,validity testing,numerical simulation,failure and deformation patterns of case and released blade.Requirements of lightweight fan case with high containment capability for the development of high bypass pressure ratio turbofan engine have been illustrated.Therefore,different structure designs of fan case of in-service and developing aero-engine for large airplane were presented,and researches on containment capability of fiber reinforced composite fan case were reviewed.The development directions of containment case for Chinese high thrust/weight engine and low-pollution civilian engine were proposed,respectively,with regard to structure improvement,low-cost manufacturing technology for composite fan case,winding pattern of full composite case,high temperature composite case,multi-disciplinary simulation of engine blade out event and smart containment case.
