Abstract: A gas turbine engine includes a core assembly with a core case having a containment section for containing liberated compressor and turbine blades and blade fragments. The containment section includes first and second containment layers and the containment section is configured to have a non- linear rate of energy dissipation across the first and second containment layers, thereby to improve containment of blades and blade fragments.
