ABSTRACT:
A fan track liner within a rotor blade assembly for a gas turbine engine comprises a radially inner casing liner member and a radially outer casing liner member adjacent to the radially inner casing liner member. A septum is interposed between the radially inner and radially outer casing liner members and bonds together the radially inner and radially outer casing liner members. The septum includes predetermined weakened regions which permit penetration of the septum in use by a rotor blade in the event of impact of the radially inner casing liner member by a detached rotor blade. Assembly otherwise capable of resisting ice shed from the blade impacting the same region.
