[0002] A gas turbine is a device that generates high-temperature, high-pressure gas by burning fuel, and then uses the kinetic energy of this gas to drive the rotation of the turbine rotor. For aircraft that require efficient and stable airflow into the combustion chamber to support high-speed combustion, such as jet aircraft or supersonic aircraft, the inlet system can help reduce airflow turbulence and vortexes, ensuring stable and efficient operation of the gas turbine.

[0003] The deflected design of the intake system helps effectively guide airflow into the gas turbine.

[0034] Reference Figure 1 、 Figure 5 The buffer assembly includes a fixed plate 15, and a through hole 16 is opened inside the fixed plate 15. The fixed plate 15 is one of the main components of the buffer assembly and is used to fix and support the structure of the entire assembly.

The right side of the two square sliding columns 17 is connected to a buffer plate 18. The function of the buffer plate 18 may be to reduce the impact or vortex that may be generated when the airflow enters the gas turbine through a certain material or structural design, thereby stabilizing the flow of the airflow.
