[0030] In order to make the objectives and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0031] First, the turbofan engine provided by the present invention is introduced. The turbofan engine at least includes a fan and a low-pressure turbine, wherein the fan is placed at the rear of the engine and forms a unit with the low-pressure turbine.
[0032] The turbofan engine also includes a high-pressure compressor, a high-pressure turbine, a high-pressure shaft, and a combustion chamber. These components can be the same or similar to the corresponding components in a common turbojet or turbofan engine. The high-pressure compressor compresses the air entering the engine. , Forming high-temperature and high-pressure air; the combustion chamber burns the high-temperature and high-pressure air to form high-temperature and high-pressure gas; the high-temper...
