<p>The invention relates to gas-turbine engines implementing the method. The invention may be used in gas-turbine engines and is directed at increasing the effectiveness and reliability of gas-turbine engines. The heated working medium is expanded, and then the thermodynamic condition of the working medium to be introduced to the turbine stage is changed by the use of an auxiliary fluid medium and it is fed to the turbine stage. A part of the working medium worked out in the turbine stage is removed and its thermodynamic condition is changed by introducing to it an auxiliary working medium, after which the worked-out medium with the changed thermodynamic condition is mixed with the heated and expanded working medium before feeding it to the turbine stage. The gas-turbine engine has a turbine stage mounted in the flow-through section (10), a source (1) of the heated and expanded working medium and a device for changing the thermodynamic condition of the heated and expanded working medium with the use of an auxiliary fluid medium. The source (1) of the heated working medium has a zone (2) of expansion of the heated working medium and a mixing zone (15) located between the expansion zone (2) and the inlet of the turbine stage (7). There is a device for changing the thermodynamic condition of the worked-out working medium which has a mixing zone (13) connected on one side to the outlet of the turbine stage (7) and to a source (5) of the auxiliary fluid medium, and, on the other side to the section (6) of the mixing zone (15) of the source (1) of the heated working medium located on the side of the zone (2) of expansion of the heated working medium.</p> |
