[0002] The air inlet not only supplies a certain flow of air to the engine, but also the air flow field of the inlet must ensure the normal operation of the compressor and the combustion chamber. The Mach number of the turbojet engine compressor inlet flow velocity is about 0.4, which has strict restrictions on the unevenness of the flow field. During flight, the air inlet must achieve deceleration and pressurization of the high-speed airflow, converting the kinetic energy of the airflow into pressure energy. As the flight speed increases, the pressurization effect of the air inlet becomes greater and greater, and the pressurization effect during supersonic flight can greatly exceed that of the compressor, so the air inlet of a supersonic aircraft plays an important role in improving flight performance;
