It is on record that rise of gas temperature in front of turbine allows to increase specific power. Consequently, it also allows to lessen overall dimensions and mass of the gas turbine plant. Authors show that analyzing parameters necessary for projecting calculation of high-temperature combustor is to be carried out with the help of thermogas dynamic calculation for open loop installation. It is noted that increase of compression index leads to the increase of excess air that raises unwanted increase of nitrogen oxide formation. Authors demonstrate the sequence of thermogas dynamic calculation, calculation variants of the gas turbine plant with different compression indexes. The analysis results show the most accurate diapason of compression index in the design of high-temperature combustor upon condition that these parameters can implement current axial flow machines of serial plant.
