A method of characterizing a turbine engine, the method comprising: steps of using measurements from an accelerometer monitoring a particular turbine engine while it is starting to detect the energy released by any contact during said starting between the rotor and the stator of the turbine engine, and of associating any such detection of contact with thermodynamic data measured on the particular turbine engine; and then a recognition training step, based on the associations, to enable a thermal context of the turbine engine to be used to recognize the presence of a rotor thermal unbalance to be taken into account in order to avoid contacts between the rotor and the stator on starting.
A method of characterizing a turbine engine, the method comprising:
An avionics device (1000) for a turbine engine (1200) for an aircraft, the device comprising means for use during engine starting to receive data from accelerometers monitoring the turbine engine and to detect therefrom the energy generated during said starting by contact between the rotor and the stator, if any, and to associate any such detection with the thermal context of the turbine engine during said starting, for a recognition training process based on the associations to enable the thermal context of the turbine engine to be used to recognize the presence of a rotor thermal unbalance that needs to be taken into account for a starting process.
