Abstract (en)
[origin: WO2011095737A1] The invention relates to a method for the automated detection of the ingestion of at least one foreign body by a gas turbine engine, according to which: the instantaneous speed of the rotor (R(t)) is measured; the speed signal of the rotor (R(t)) is filtered in order to separate the static component (Rs(t)) from the dynamic component (Rd(t)) thereof; the filtered dynamic component (Rd(t)) is compared with a standard resonance wave (e(t)) of the rotor in order to obtain an ingestion indicator (TING), the standard resonance wave (e(t)) corresponding to the vibrational impulse response of a rotor; the obtained ingestion indicator (TING) is compared with a detection threshold (S); a foreign body ingestion detection signal is emitted when the ingestion indicator (TING) is higher than the detection threshold (S).
