A fan containment system for fitment around an array of radially extending fan blades mounted on a hub in an axial gas turbine engine. The fan containment system (300) comprises a fan case (350) having an annular casing element (352) for encircling an array of fan blades and a hook (354) projecting in a generally radially inward direction from the annular casing element. An annular fan track liner (356) 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 (364) 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 (364) is configured to fail 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. |
