ABSTRACT:
A turbofan gas turbine engine (10) comprises a fan rotor (32) carrying a plurality of radially extending fan blades (34). A fan blade containment assembly (38) surrounds the fan blades (34) and the fan blade containment assembly (38) comprises a generally cylindrical, or frustoconical, metal casing (40). The casing (40) comprises an annular member (54) positioned axially upstream of the tip (37) of the fan blade (34). The annular member (54) extends in a radially inwardly and axially downstream direction from the metal casing (40) towards the tip (37) of the fan blade (34). A set of acoustic panels (72C) is also provided. A set of acoustic panels (72B) is secured to the metal casing (40) by resilient fingers (80, 84) on the upstream and downstream ends (82,86) of the acoustic panels (72B) which locate on the annular member (54) and the acoustic panels (72C).
