* The How to access global trade archivesprinciple of jet engine (Introduction to the working mechanism of the jet engine) A jet engine is a power device that can mix air and fuel and burn to generate high-speed airflow to push the fuselage forward. Judging from the structure and working principle of the jet engine, it is different from the internal combustion engine, rocket engine, etc., and is also the core part of the modern aircraft propulsion system.The basic components of the jet engine include compressor, combustion chamber, turbine and nozzle, etc. The air enters the compressor from the outside of the aircraft. After compression, it enters the combustion chamber, mixes and burns with the fuel to generate heat energy, and then passes through the turbine to drive the bearing and drive the rotation of the compressor to form a cycle. Finally, high-speed airflow spewed out of the nozzle, pushing the plane forward. In jet engines, the most important thing is the compressor. The compressor is composed of continuous impellers and fixed guide blades, and the airflow produced can reach 200 times the pressure of the intake. This high-pressure airflow is sent into the combustion chamber, mixed with fuel and burned in the flame, so it is also called a flame chamber. The thermal energy generated during combustion can not only provide the thrust of the jet engine, but also drive the system inside the jet engine.At this time, the high-temperature hot airflow generated by combustion will generate huge pressure, driving the turbine blades to rotate rapidly. The turbine is supported by the broken shafts of the front and rear wheels, and is mainly composed of turbine tires and several turbine blades. After the hot air flow is sprayed out through the nozzle, it will rotate these blades rapidly and bring them up to move into a rotating pneumatic machine. The high-speed turbine blades are connected to the compressor shaft to send the compressed airflow into the combustion chamber, thus powerfully driving the entire engine. As one of the 'core components' of the jet engine, it is indispensable, which not only has a great impact on the output power of the jet engine, but also plays an important role in the operating efficiency of the jet engine. The nozzle behind the turbine is one of the most important parts of the jet engine. It mainly plays a propulsing role, ejecting high-temperature and high-pressure gas.Come, the formation of a huge thrust, the updated and compensated airflow is the final force that produces the jet effect, so that the jet engine can play its original intention. In aviation engineering, the nozzle is one of the important points for speed accumulation and performance in flight. The working principle of the nozzle is to achieve injection by properly controlling the structure and flow rate of the nozzle. The design of jet engines depends on the continuous evolution of aerodynamics and friction. Therefore, when the appropriate airspeed is reached, the circulation inside the jet engine will begin, and even under extreme working conditions, the cycle speed of the jet engine will rise rapidly in a short time. But at the same time, jet engines also need to consider the characteristics of good durability and low volume to ensure the stability and comfort of maneuverability. Therefore, when designing a jet engine, it is also necessary to consider factors such as production efficiency, management difficulty, technical difficulty, etc., which have an impact on its working mechanism.In summary, the working mechanism of the jet engine has been fully understood, but there are still many details that need to be improved to improve the durability, safety and economy of the jet engine. With the continuous development of science and technology, commercial aircraft are increasingly relying on advanced jet engines to support aerial flights. At the same time, in order to ensure the smooth take-off and landing of the aircraft, the jet engine also needs to be constantly maintained and inspected to ensure the correctness and stability of the working mechanism.
