A fan containment system (200) arranged to be fitted around an array of radially extending fan blades (40) mounted on a hub in an axial gas turbine engine. The fan containment system comprises: a generally cylindrical fan case (250) including a hook (260) projecting in a generally radially inward direction and positioned axially forward of the radial array of fan blades; a fan track liner (252) disposed on the radially inner surface of the fan case; and a panel (300) which is positioned axially rearward of the hook and axially forward of the radial array of fan blades. The panel is temporarily deformable so as to absorb the impacts of foreign bodies, while being weak enough so that if a fan blade is released from the hub, the tip of the detached fan blade can move radially outward, collide with the hook and be retained in the gas turbine engine. |
