Review of aero-engine case containment research

Aeroengine uncontained accident would threaten the safety of passenger and caused the crash of plane, and therefore the containment capability was strictly defined in the military and civilian aeroengine standards in the world. The progress of composite materials science and manufacturing technics has greatly promoted the research on composite case with high capability and light weight in recent years. In this paper, a review on the research of aero-engine case containment capability is presented with a detailed illustration of the definition of aero-engine containment, design concepts, case materials, validity experiment and testing, numerical simulation, failure and deformation of case and released blade, high bypass ratio turbofan aero-engine fan containment case, and so on. The development directions of containment case for Chinese high thrust/weight military engine and low-pollution civilian engine are proposed.
