Abstract (en)
[origin: WO2021148731A1] An aspect of the invention relates to a method for monitoring a starting sequence of a turbomachine comprising a compressor provided with a rotor, a starter capable of rotating the rotor and a combustion chamber, the method comprising the following operations: - determining (110) a bracketing (E) of a time zone during which the ignition instant takes place, the bracketing being defined by, on the one hand, a lower limit (E1) corresponding to an event necessarily taking place before the ignition instant and an upper limit (E2) corresponding to an event necessarily taking place after the ignition instant; and - determining (130-190) between the lower limit (E1) and the upper limit (E2), a break point (A) in the variation with time of the measurement signal, this break point corresponding to an ignition instant of the air-fuel mixture in the combustion chamber.
