    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 invention relates to a method and device for adjusting a threshold value of a fuel flow rate, which includes: a step of obtaining (E20) a first estimate (E1) of a fuel flow rate injected into a combustion chamber of a turbine engine propelling an aircraft, provided by a fuel metering device of the turbine engine; a step of obtaining (E30) a second estimate (E2) of the fuel flow rate, which is more accurate than the first estimate for at least one interval of fuel flow rate values, provided by an estimation device having a flow meter; and a step of adjusting (E70, E80) the threshold value (C0(acc), C0(dec)) of the fuel flow rate using a difference (AE) evaluated between the first estimate (El) and the second estimate (E2), said threshold value to be used in an open loop for controlling the turbine engine.

    摘要： The estimation method according to the invention includes: a step of digitally modeling the jet temperature by means of a modeled signal (T1); and a step of correcting said modeled signal by means of an error signal (T2), the signal being obtained after correction (T3) representing an estimate of the jet temperature. According to the invention, when predetermined conditions related to at least one jet engine operating phase and to thermal stability are verified, the error signal (T2) is updated on the basis of the modeled signal (T1) and a jet temperature measurement signal (T4) produced by a temperature sensor (40).
