concentric摘要：A gas turbine engine (10) compris a fan rotor (26) having a plurality of fan blades (24) and an apparatus (34) for detecting an impact on the fan blades (24). The apparatus (34) compris speed nsors (48,48B) arranged to measure the speed ofheader card
rotation of the fan rotor (26) and the turbine rotor (58) and to produce speed signals. A processor unit (40) analys the speed signals to determine the angle of twist between the ends of the fan rotor (26). The processor unit (40) is arranged to analy the angle of twist to determine if the angle of twist of the fan rotor (40) oscillates by more than a predetermined level from an average level. The processor unit (40) is arranged to produce a signal indicative of an impact to at least one of the fan blades (24) if the angle of twist oscillates by more than the predetermined level and nds a signal to an indicator device (44,46).
