A technique was developed for determining the minimum specific fuel consumption of a two-circuit turbojet engine using statistical data on the polytropic efficiency of individual compressor and turbine stages. The proposed method allows the presence of a technological advantage in specific fuel consumption compared to similar engines to be identified at the initial stage of designing a two-circuit turbojet engine.
