Current status of turbojets and their future

Abstract

As one of the important equipment components, aeroengine reflects the national aviation development level and has an important strategic position and value. At present, there are four main types of aeroengines. This paper focuses on the mechanical structure, energy transfer mode, thrust weight ratio and existing defects of the turbine engine. From the point of view of mechanical design, the motion principle of engine components is discussed. From the point of view of energy, the performance test method of engine afterburner is studied, several feasible test schemes are proposed, and the application of turbine engine in miniaturization is discussed. From the point of view of energy saving, the power, maximum torque and thrust gravity ratio of naturally aspirated engine and turbine engine are compared, and the advantages and disadvantages of turbine engine are analyzed. Finally, the future development direction of aeroengine is studied, such as the wide application of new generation plasma engine and more efficient reburning afterburner.
