Abstract

La présente invention concerne un procédé de recalage de modèle de pression statique en amont de chambre de combustion (mod_Ps3(PCN25R)), dit « modèle de Ps3», dans une turbomachine comprenant un compresseur (3), le modèle de Ps3 étant utilisé pour arbitrer entre deux voies d’acquisition (V10, V20) de la pression statique en amont de la chambre de combustion (Ps3), dite « pression Ps3», les deux voies d’acquisition (V10, V20) faisant intervenir deux capteurs (10, 20), le modèle exprimant la pression Ps3 en fonction au moins du régime (PCN25R) du compresseur (3), dit « régime PCN25R » et comprenant les étapes suivantes : E1 : mesure d’une valeur de la pression Ps3, par un des deux capteurs (10, 20),E2 : recalage du modèle de Ps3 à l’aide de la mesure de la valeur de Ps3. Figure pour l’abrégé : Fig. 3The present invention relates to a method for resetting the static pressure model upstream of the combustion chamber (mod_Ps3 (PCN25R)), called a “Ps3 model”, in a turbomachine comprising a compressor (3), the Ps3 model being used for arbitrate between two acquisition channels (V10, V20) of the static pressure upstream of the combustion chamber (Ps3), called “pressure Ps3”, the two acquisition channels (V10, V20) involving two sensors (10 , 20), the model expressing the pressure Ps3 as a function at least of the speed (PCN25R) of the compressor (3), known as the “PCN25R speed” and comprising the following steps: E1: measurement of a pressure value Ps3, by a of the two sensors (10, 20), E2: recalibration of the model of Ps3 using the measurement of the value of Ps3.
