摘要: A method for detecting resonance in a rotor shaft of turbine engine, which frequency (Fr) the belonging to band is centered on an estimated (Frest), disclosed. The including: measuring parameter (P) regulating fuel engine measured obtain excitation signal; forming spectrum comparing amplitude signal compared with threshold (S) spectrum; and emitting detection alarm if exceeded.
