<p>A fan containment system 300 for fitment around an array of radially extending fan blades 40 of a gas turbine engine comprises a fan case 350 having a casing element 352 for encircling the fan blades and a hook 354 projecting in a radially inward direction from the annular casing element and positioned axially forward of the fan blades. An annular fan track liner 356 comprises a plurality of adjacent arcuate fan track liner panels 384a, 384b and each fan track liner panel is connected to the fan case at the hook via one or more fasteners 366 configured to permit movement of the fan track liner panel relative to the hook such that the fan track liner panel can pivot towards the annular casing element when a pre-determined load is applied to the fan track liner panel. A region 388 of the hook adjacent a boundary between two adjacent fan track liner panels is profiled so as to accommodate travel of a released fan blade.</p> |
