Design and development of AVIC Commercial Aircraft Engine Co., Ltd. affiliated to aviation industry corporation of china. The turbofan engine with large bypass ratio can be used as the power of large military commercial aircraft, which consists of 1 stage fan, 3-stage booster compressor, 7-stage high-pressure compressor, short-ring combustor, 1 stage high-pressure turbine, 3-stage low-pressure turbine, simple convergent nozzle and full authority digital control (FADEC) system.
According to foreign media speculation, this large bypass ratio turbofan engine has entered the test flight stage and will be put into use in the next 5 to 7 years. So far, China has become the fifth country to independently develop high-performance turbofan engine with large bypass ratio after the United States, Britain, France and Russia. This type of engine not only fills an important gap in the field of aero-engines in China, but also is a milestone in the development of aero-engines in China.
It can be said that after this hurdle, China aero-engine will officially enter the "fast lane" of development, just like breaking through the "enough paper", and a series of advanced technologies will be conquered one after another.
In addition to developing the dual-purpose turbofan -20 engine, China is also developing the Changjiang-1000A engine for C-9 19 civil aircraft, and plans to produce the LEAP-X engine with world-class level in China.
In addition, China has been studying a variety of advanced large bypass ratio engines, and the next generation thrust is 200-400 kN. There are various indications that the spring of China's large bypass ratio engine has arrived.
