The reporter learned from the 31st China Aerospace Science and Industry Institute on the 28th that China’s first 650 kg turbofan engine with its own intellectual property rights has recently come into existence. The engine is suitable for use in long-haul, wide-range commercial civilian aircraft and provides reliable power for civil drones and small business jets.
It is reported that this dual-rotor turbofan engine was independently developed by 31 teams, using a high-efficiency forward-swept fan, axial flow + diagonal combination compressor, large expansion channel high and low pressure turbine integrated design, electric fuel oil pump, starting the generator Built-in and many other key technologies, as well as advanced electrical, control systems and health management systems. It has high performance, compact structure and other characteristics, and has reached the leading level of domestic small engines. The development team lasted ten years and successively completed the design, trial production and production of the engine, as well as a large number of components and complete machine tests. In the near future, the durability test and high altitude test were carried out to verify the correctness of the design scheme.
At the China International Aerospace Technology and Equipment Exhibition recently held, the engine was unveiled for the first time and received attention and highly appraisal from counterparts of the Chinese Academy of Sciences, China Aviation, and Tsinghua, and attracted marine police, agriculture, drone companies, and the government. Departments and other areas of customer consultation negotiations. (Zhang Hao Reporter Fu Yifei)
