The first half of C929 has been completed offline, CJ2000 is ready, and 2030 is expected to make its first flight!

Recently, the Russian side once again raised the C929 cooperation project, saying that Russia will not withdraw from this Sino Russian cooperation project, which makes many people wonder if they have always said they want to withdraw from this project? Why do you suddenly want to continue working together? However, later news came out from the Russian side that China would contract and develop the C929 aircraft project, which had withdrawn from cooperation with China. Unfortunately, China had lost Russia as a partner at that time, as Russia still had a lot of technology to learn from in the aviation industry; With the exposure of a series of achievements made by China in C929, it has become clear to everyone that the progress of C929 is about to be realized, and it is no wonder that even if the cooperation is terminated, China needs to independently contract to continue the research and development of the project

More importantly, currently only China can produce this composite material in the world, which means that China has formed a monopoly on this aircraft material. If other countries also want to manufacture this type of fuselage, they must come to China to purchase materials, and if they have purchased enough, they must also come to China to manufacture this type of fuselage, because only China can process large components made of this composite material.

Since the fuselage is ready, the engine is no exception. The CJ2000 engine on the other side is also ready, and the core engine has been successfully developed. According to the published data, the thrust of the CJ2000 has reached 343KN, while the thrust of the GenX engine used by the Boeing 787 Dreamliner is only 330KN. The design of the two airliners is similar, and both adopt the three cabin design. The cockpit of the Boeing 787 Dreamliner is 242 to 335, the cockpit of the C929 is about 290, and the Boeing 787 Dreamliner is the first ultra long range medium-sized airliner in the world. From this, it can be concluded that the performance of the CJ2000 engine is among the top in the world, and its economic applicability is also very high. In terms of safety, it can be seen from the failure rate of aircraft that have used domestic engines in China in the past, how reliable it is.

Since even the fuselage has been manufactured and the engine is ready, it means that the most core parts of the C929 have been completed. It won't be long before the first flight, and after the first flight is completed, a period of safety testing will be conducted. Then, it can enter the formal production stage and enter the international market to allow this large aircraft to fly globally.

CJ-2000 engine

Before that, Russia wanted to withdraw from the C929 project for many times because of difficulties in the fuselage and engine. The original engine of the C929 was British engine, and in order to obtain Airworthiness certificate from western countries, the aircraft also used many electronic equipment and accessories from western countries; Later, because of the Russia-Ukraine conflict and other factors, the supply of engines was difficult, and the supply of electronic equipment and accessories was also blocked.

The solution proposed by Russia is to use domestically produced equipment from Russia to replace it, but our country did not agree to this requirement because it may lead to increased costs and a decrease in the reliability of these equipment. After all, the equipment of such a modern passenger aircraft from Russia was relatively good in the last century, but it is not enough to look at it now; In addition, facing comprehensive sanctions from Western countries, Russia needs to build a passenger aircraft that is completely free from Western dependence. Therefore, Russia terminated its cooperation with China's C929 and instead developed its own domestic passenger aircraft.

And what about our country? Of course, there is no such concern. China has already made domestically produced composite materials on the aircraft body, which are unique to the world. The use of Western countries' equipment and accessories is for cost considerations. Domestically produced ones are not absent, but are slightly higher in cost, and there is no need to worry about Western sanctions. During this period, Western leaders and corporate executives have visited China one after another to seek cooperation, which is a best example, These people are eager for our country to use their products, how can they rush to cut off the supply? Based on the current situation, the engine can be fully assembled within two years, and the assembly of the entire machine is also within these few years. It is not impossible to achieve the first flight by 2030 after the complete machine is assembled. With the experience accumulated by C919, it may be uncertain whether this time will be one step ahead.
