Abstract: Method for monitoring the distribution of power in a hybrid propulsion system comprising one or more electrical sources delivering an AC voltage, each of which is associated with an AC-to-DC controlled rectifier and one or more batteries, wherein, the AC-to-DC controlled rectifier and the battery each being connected directly to an HVDC bus supplying one or more electrical loads with power, the monitoring of the distribution of power is performed through the individual AC-to-DC controlled rectifier by a feedback loop to a power setpoint (Pref) on the basis of a measured power of the battery (Pbat) and a feedback loop to a voltage setpoint (Vref) on the basis of a measured voltage of the HVDC bus (VHVDC), either one of these two feedback loops delivering an RMS current setpoint Idref and Iqref for a feedback loop on the basis of a current (Igen) of the electrical source delivering an AC voltage.

Abstract: A method is provided. The method includes, after a landing of an aircraft, detecting by sensors the position of the landing gear at a first sampling frequency, while the position of the landing gear is detected as vertical. After detection of a horizontal position of the landing gear, detecting by the sensors the position of the landing gear at least at a second sampling frequency, while the position of the landing gear is detected as horizontal. After detection of a vertical position of the landing gear, acquiring by said sensors physical parameters relating to the ageing of the landing gear, and detecting a landing of the aircraft at a third sampling frequency until a predetermined period has expired. The third frequency is greater than the second frequency, which is greater than the first frequency. Measurements relating to the ageing are stored as a function of the measured physical parameters.
