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.
