Abstract
A stage of fan aerofoils () lies within a fan cowl (). The fan duct () is defined in part by a hard casing () that in turn surrounds aerofoils (). Hard casing () includes wedge members () that fill the annular gap between ring () and an outer ring (). In the event of an aerofoil () breaking off, the hard ring () and wedges () absorb sufficient of the kinetic energy expended by the broken aerofoil (), as to prevent it passing through outer ring () on to the fan cowl ().
