Nowadays, the research and development of the second large aircraft C929 is in steady progress, as a large aircraft with extremely high technical difficulty and manufacturing threshold, we have adopted a joint public relations approach, that is, led by COMAC, domestic airlines, universities, research institutes and aviation manufacturing enterprises to participate in it, and different manufacturers will be responsible for the research and development of different parts and technologies.
It is worth noting that there are a lot of good news about the C929 large aircraft recently, and China Aviation Development Group has also disclosed the relevant news about the domestic aviation engine supporting the C929 large aircraft. In fact, it can be seen from these news that the research and development of our C929 large aircraft is progressing steadily, and some industry insiders believe that our C929 large aircraft may make its first flight earlier than expected in 2030 at the beginning, and advance to about 2029.
The C929 aircraft has a total of ten core systems, including avionics system, flight management system, power plant, communication and navigation system, etc. At present, the ten core systems of our C929 large aircraft have been fully technically verified, and now we have officially begun to enter the stage of component production and system integration of engineering prototypes.
This is also the most important stage in the research and development of a large aircraft, once this stage of research and development, verification, basically means that more than half of the problems in the development and manufacturing of C929 large aircraft have been solved. It is worth noting that among the ten core systems, all the systems that we have domestic technology and the technical level can be guaranteed are the domestic systems.
Judging from the current news, including the power unit and structural design, they are all made of domestic technology. In terms of structural design, we have also adopted emerging technologies such as emerging composite materials and lightweight design, as well as 3D printing technology to complete the production of some complex and large parts, which not only reduces material consumption, but also greatly reduces costs.
It is worth noting that although in the current design stage, the C929 large aircraft is still expected to be equipped with imported engines, but we are also making domestic backups, that is, our CJ2000 engines. The engine was developed earlier than the C929 and will be a bit faster, and should be able to get validation results before the C929 is developed. In fact, this also means that the C929 large aircraft is likely to carry the "Chinese heart" aviation at the beginning.
In addition to the ten core systems, the C929 large aircraft has the advantages of high-tech cockpit and luxury cabin, among which the cockpit has advanced design concepts, advanced avionics equipment integration solutions, and the latest HMI human-machine interface technology. In terms of cabin design, the C929 large aircraft adopts some innovative technologies, which can effectively bring more high-quality comfort to passengers, and the first class cabin also has a flat-lying seat design, adjustable lighting system, etc.
In order to meet the needs of different airlines, the C929 large aircraft also has customized services, and airlines can adjust the cabin layout to a certain extent according to their own needs.
From these data, it is not difficult to see that our C929 large aircraft not only has a very rapid development process, but also has outstanding performance parameters in all aspects, including the use of many advanced technologies, with lower energy consumption, less noise, etc. It can be said that it is also at the leading level among the benchmark wide-body medium and long-range large aircraft.
