Subsonic bypass turbojet engines of the fifth generation have reached technical maturity, with overall efficiency of 35–38%. Without changing the thermodynamic cycle of the engine, any further work in this direction is futile. The researcher proposes a method of increasing the thermodynamic effectiveness of heat engines based on the so called internal ...
