    摘要： The invention relates to a method for detecting the ingress of water or hail into a turbine engine, said turbine engine including at least one compressor (4), a combustion chamber (1), and a turbine (2). The method includes the following steps consisting in: estimating the value of a first indicator representing an ingress of water or hail; estimating the value of a second indicator representing an ingress of water or hail, said second indicator being different from the first indicator; and calculating the value of an aggregate indicator by adding together at least said first and second indicators.

    摘要： The setpoint signal (C1) represents a delivery of fuel to be supplied by a slide-valve type (in-line) metering device (2) to a fuel injection system (4) for injecting fuel into a combustion chamber of a turbomachine, the position of the slide valve (2A) being dependent on the setpoint signal. The method involves: obtaining a first signal (S1) representative of a measurement delivered by a flow meter (6) of a delivery of fuel injected into the chamber; evaluating a second signal (S2) representing the delivery of fuel injected into the chamber on the basis of a measurement (M) of the position of the slide valve; estimating a third signal representing the measurement delivered by the flow meter by applying a numerical model of the flow meter to the second signal; formulating the setpoint signal by adding to the first signal a compensation signal that is obtained by subtracting the third signal from the second signal.
