Abstract
A fan track liner within a rotor blade assembly 26 for a gas turbine engine (10, FIG. 1) comprises a radially inner casing liner member 28 and a radially outer casing liner member 30 adjacent to the radially inner casing liner member 28. A septum 32 is interposed between the radially inner and radially outer casing liner members 28, 30 and bonds together the radially inner and radially outer casing liner members 28, 30. The septum 32 includes predetermined weakened regions 36 which permit penetration of the septum 32 in use by a rotor blade in the event of impact of the radially inner casing liner 28 member by a detached rotor blade. Assembly 26 otherwise capable of resisting ice shed from the blade impacting the same region 36.
