摘要： The invention relates to a method for monitoring an LVDT sensor comprising two secondary circuits, characterised in that it comprises the iterative steps of: calculating (E1) the difference between the voltages at the terminals of one of the secondary circuits at a given moment and at a preceding moment; calculating (E1) the difference between the voltages at the terminals of the other secondary circuit at the given moment and at the preceding moment; calculating (E2) the sum of two calculated differences; modifying (E3) an indicator in accordance with the distance from zero of the previously calculated sum; and comparing (E4) the indicator with at least one predetermined threshold.

摘要： The method according to the invention comprises, during a phase (EO) of starting up the turbomachine : — a step (E10) of open-loop generation of a control (WF_OL) of the flow of fuel based on at least one pre-established law; and — a step (E20-E30) of closed-loop monitoring of at least one operating parameter of the turbomachine selected from: o an acceleration rate (dN2/dt) of a compressor of the turbomachine, and o an output temperature (EGT) of a turbine of the turbomachine, this monitoring step comprising keeping (E30) the operating parameter within a range of predefined values, using at least one corrective network (R1, R2, R3) associated with this parameter and capable of providing a correction signal correcting the fuel flow control generated in an open loop manner, making it possible to keep the operating parameter within the range of predefined values.

摘要： The invention relates to detecting an icing condition of a fuel circuit (1) of a turbine engine including: a step of acquiring information representative of a first fuel temperature T
1 downstream from the fuel metering valve (10) and of the comparison of the first temperature T
1 to a first reference temperature Toi; a step of detecting a clogging of the filtration unit (6); and, in the event the measured temperature T
1 is lower than the first reference temperature Toi and a clog is detected, transmitting a signal indicating an icing condition of the fuel circuit (1). Information representing a second temperature T
2 of the fuel in the tank (3) can be acquired and compared to a reference temperature T02 to confirm or render the icing condition invalid. A signal indicating a need for servicing a fuel circuit is transmitted when the acquired temperatures T
1 and T
2 are not lower than the reference temperatures Toi and T02 while a clog is detected.
