METHOD FOR ESTIMATING A JET TEMPERATURE IN A JET 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).
