Abstract
A fan containment system has a fan case having an annular casing element for encircling an array of fan blades and a hook projecting generally radially inwardly from the annular casing element. An annular fan track liner is positioned substantially coaxial to the annular casing element, and positioned such that a forward end of the fan track liner is axially spaced from the hook so that there is a gap between the hook and the fan track liner. A bridge member spans the gap between the hook and the fan track liner, wherein the bridge member is connected to the hook and contacts a radially inner surface of the forward end of the fan track liner. The bridge member fails when impacted by a fan blade released from a hub so that the released fan blade can impact the hook and be contained by the fan containment system.
