Abstract

Official abstract text for this publication.

A method for automated detection of ingestion of at least one foreign body by a gas turbine engine, according to which: instantaneous speed of the rotor is measured; a speed signal of the rotor is filtered to separate a static component from a dynamic component thereof; the filtered dynamic component is compared to a standard resonance wave of the rotor to obtain an ingestion indicator, the standard resonance wave corresponding to the vibrational impulse response of a rotor; the obtained ingestion indicator is compared with a detection threshold; and a foreign body ingestion detection signal is emitted when the ingestion indicator is higher than the detection threshold.

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for automated detection of ingestion of at least one foreign body by a gas turbine engine including a rotor, the method comprising: measuring instantaneous rotational speed of the rotor; filtering a speed signal of the measured instantaneous rotational speed of the rotor to separate a static component from a dynamic component thereof; treating the filtered dynamic component of the speed signal and a standard resonance torsion wave of the r…
