As we all know, the United States has been imposing various sanctions against China to block the export of high-end technological products and equipment. However, what is puzzling is that the United States has not yet imposed a ban on the sale of large aircraft engines to China. What's the secret behind this?
As the world's largest manufacturer of military and civilian aviation, Boeing is critical to the U.S. economy and its leadership in aviation. However, since 2018, Boeing has not received any orders from China. This made the United States very worried, so it repeatedly threatened to remotely shut down the engine of the C919 even if China paid liquidated damages.
However, we cannot be gullible about such threats. Unlike electronic products such as lithography machines, engines are mechanical products, and there is no precedent for remote control of engines in the world. In addition, before importing engines, China strictly inspects and tests them, and if they feel that there are any problems, they have already discovered and taken corresponding measures to solve them. Therefore, the US threat is not only groundless, but also undermines its own credibility and interests.
However, we cannot ignore this warning. If the C919 obtains a foreign airworthiness certificate, successfully enters the international market, and poses a threat to Boeing and Airbus, the United States may adopt a similar approach to Huawei, directly blocking China's large aircraft engines. This would have a catastrophic impact on C919. Because life safety is involved in aviation, once an engine is disabled, we not only lose market share, but also need to re-go various declaration processes and procedures, which consumes a lot of time and energy. At the same time, the replacement of the engine will lead to a redesign of the layout of the aircraft as a whole, which is equivalent to starting from scratch. So once the U.S. gets its hands on C919 success, we're going to have a huge challenge.
However, we were prepared. China has not only made great progress in the fields of machine tools, software, chips, etc., but also has continuously increased its independent innovation in the aviation field. We have successfully tested the CJ-1000A engine, which is an alternative to the LEAP engine, which is already capable of being used in the domestic C919 airliner and has essentially the same performance. The CJ-1000A engine has made breakthroughs in a number of technologies, with advantages such as increased thrust, noise reduction, improved efficiency and reliability.
First of all, the maximum thrust of the CJ-1000A engine can reach 13-15 tons, which has already surpassed many foreign engines of the same class. Secondly, the engine uses advanced material technology and three-dimensional aerodynamic design to achieve lower noise and better safety performance, while improving the efficiency and reliability of the engine. In addition, the engine's fan also adopts three-dimensional wide-chord hollow blades with a small aspect ratio, which further improves the aerodynamic performance and work efficiency. After 400 component tests and many trials and tests, the technology and quality of the CJ-1000A engine have been fully verified.
It is worth mentioning that we are still working intensively on the CJ2000, which is an upgraded version of the CJ-1000A, with an estimated thrust of 35 tons. So whether the United States bans engines or not, we are ready. If the U.S. continues, we will continue to adopt;If the United States plays tricks, we can switch engines at any time and adopt a two-legged strategy to avoid repeating what happened to Huawei.
China has completed hundreds of years of industrialization in the West in just 40 years, and with the hard work and innovative spirit of the Chinese, we are expected to become one of the world's largest industrial powers. At present, the C919 in China has been put into commercial use, although the number is not large, but this is mainly because we need to ensure the reliability and safety of the engine. With the continuous advancement of technology, we believe that the C919 and China's aviation industry will usher in greater development.
Therefore, while the United States may still exert pressure on us, we should maintain our confidence and continue to work hard to promote independent R&D and innovation. We already have our own domestic engine, and we are constantly improving and improving the performance. This will also provide new impetus and guarantee for the future development of China's aviation industry.
In short, there is no secret deal behind the fact that the United States has not yet imposed a ban on the sale of China's large aircraft engines. We are ready for this, whether we continue to use imported engines or switch to in-house development, we have a solution. We believe that through our efforts and innovation, China's aviation industry will usher in better development.
