The aircraft engine issue is always the bottleneck of China's aviation manufacturing industry and large China-made aircraft which will be launched in 2016 will adopt imported CFM engines, but will adopt China-made engines in the future, said Yi Zeyong, a member of the Chinese People's Political Consultative Conference (CPPCC), academician of the Chinese Academy of Engineering, and an aircraft engine expert, March 9 to the Netease Money website.

Yi said that there is no question that China's first step of developing engines for its independent large aircraft is to cooperate with foreign countries. The task of independently researching and developing engines for the C919 aircraft has been delegated to the Aviation Industry Corporation of China, and "we hope it will succeed as soon as possible."

Gao Zhenghong, a member of the CPPCC and a professor at the School of Aeronautics under the Northwestern Polytechnical University, believes that generally, if people want to design an aircraft, the first thing they design is the engine, and other parts of the plane will be designed based on the engine's power conditions. Currently, the engine issue has become the bottleneck of China's aircraft research and development.

The 2 members suggest that China should regard the development of aero-engines as an important technical project, list it in the "12th Five-Year Plan" and invest more funds and human resources in its development.

Yin demonstrated that the aero-engine technology is universally regarded as the core of aircraft technology. When Airbus was incorporated, the British government continued to develop and produce its own aero-engines, and even wrote it in law that foreign ownership of Rolls-Royce should be limited to 15 percent. In general, the research funds of aero-engines are around 2 billion U.S. dollars. For example, the M88 cost France 1.6 billion U.S. dollars, and the F119 cost the U.S. 2.6 billion U.S. dollars. Moreover, the U.S. spent a total of 17 years and 5 billion U.S. dollars on the Integrated High-Performance Turbine Engine Technology (IHPTET), 6 times of China's 20-year total investment in aero-engine pre-research.

"It is worth noting that Japan and India are trying their best to acquire the aero-engine core technology through international procurement and cooperation at any price, so we should pay special attention to the development of the aero-engine," Yin emphasized.
