FIELD: machine building; physics.
SUBSTANCE: present invention relates to a method of correcting a static pressure model (mod_Ps3 (PCN25R)), referred to as a Ps3 model, at the inlet of a combustion chamber in a gas turbine engine comprising compressor (3), wherein the model Ps3 is used to make a choice between two channels (V10, V20) for obtaining static pressure data (Ps3), called pressure Ps3, at the inlet of the combustion chamber, wherein two data acquisition channels (V10, V20) use two sensors (10, 20), wherein the model expresses pressure Ps3 as a function of at least a mode (PCN25R), called PCN25R mode, of compressor (3) and the method includes performing the following steps: E1: measurement of pressure value Ps3 by means of two sensors (10, 20), E2: correction of model Ps3 by means of measurement results of pressure value Ps3.
EFFECT: model correction in gas turbine engine is disclosed.
