Abstract
A fan containment case assembly of a gas turbine engine includes a hardened fan case liner disposed therein. In the event of a fan blade loss condition, the hardened fan case liner allows for circumferential movement of the fan blade tips around the fan case . Thus, the liner reduces the destructive cutting away of the fan case, minimizing damage to the fan case and decreasing torque loading of the fan case from rotor deflections. Alternate embodiments of the fan case liner are described.
