Abstract (en)
Method for determining an outlet temperature (T<sub>2</sub>) of an upstream combustion stage (21) in a gas turbine engine having at least two serially arranged combustion stages (21, 22), a compressor (10) fluidly communicatied with and upstream a most upstream combustion stage (21), and a last expansion turbine (30) fluidly communicated with and downstream a most downstream combustion stage (22). The method comprises obtaining at least one first parameter representative of the inlet temperature (T<sub>3</sub>) of the most downstream combustion stage (22), obtaining at least one second parameter representative of the outlet temperature (T<sub>1</sub>) of the compressor (10), and obtaining the fuel massflows (ṁ<sub>Fuel,1</sub>, ṁ<sub>Fuel,2</sub>) and/or a fuel massflow ratio between the combustion stages (21,22). An outlet temperature (T<sub>2</sub>) of an upstream combustion stage (21) is obtained based upon said first and second parameters and the fuel massflows and/or the fuel massflow ratio.
