COMAC has news that the C919 engine may be localized
The C919 is a wide-body aircraft project independently developed by China, the first aircraft was delivered in December last year, and was fully put into commercial operation some time ago.
But as far as the aircraft itself is concerned, many expect a higher rate of localization and less dependence on foreign technology. In this regard, COMAC has announced that the engines of the C919 aircraft can be localized.
Throughout the history of human aviation, the global aviation market has so far been monopolized by Boeing and Airbus, two passenger aircraft manufacturers second only to the United States and France, representing European and American technologies at the top of the industry pyramid.
However, the fact that COMAC mass-produced the C919 proves that the monopoly of Boeing and Airbus is being broken. C919 has been established for a total of 16 years, and a lot of manpower and material resources have been invested, and national universities, scientific research institutions and enterprises in the aviation industry chain have participated in it.
But it must be admitted that it is almost impossible to build aircraft autonomously. What's more, China's aircraft manufacturing industry started late and has less experience than abroad, resulting in some technologies such as C919 engines that need to be imported from abroad.
For example, the engine type of the C919 is LEAP-1C, which is supplied by CFM International, the flight control system is provided by Honeywell, and the avionics system is provided by General Electric. In the proportion of C919, Western technology accounts for about 40%, of which engines account for the vast majority.
If we can successfully replace the domestic engine, other basic technologies should be overtaken one by one. In fact, China also has its own engine project, and it was originally planned to equip the CJ-1000A with C919, but due to problems such as a long R&D cycle, it cannot be used with C919.
On the positive side, the CJ-1000A engine is currently undergoing test flights. Some netizens photographed the Y-20 aircraft equipped with a height-to-width ratio turbofan engine for test flights, and its configuration is three thin and one thick, which is not consistent with the normal engine configuration of the Y-20. The WS-20 carried by the Y-20 has been equipped, and now there are three thin and one thick engines, which are likely to be engine test benches and engines for test flights, that is, CJ-1000A.
In fact, there has been more than one news about the progress of the CJ-1000A engine project, and it was previously reported that the CJ-1000A has completed relevant tests and is being tested for flight verification on the modified GM-20 platform. At the beginning of this year, the Aviation Industry Flight Test Center completed the first verification flight of the general aviation platform, so that China has the ability to independently develop the general aviation engine flight platform.
In other words, this provides more test and verification conditions for domestic engines to meet the corresponding performance requirements, and further adjusts and revises the engine parameters, and improves them by obtaining a large amount of power data.
It is important to know that the test validation of aero engines is very complicated, because almost all the components used in the engine are inspected separately. For example, compressor testing, combustion chamber testing, tail nozzle testing, and many more.
These are only the preliminary test work, for the later test part to test the ability to fly at high altitude, environmental adaptability adjustment in the high-pressure atmospheric meteorological environment, and so on. Therefore, in the development process of aero engines, aero engines that can be put into commercial use have undergone many improvements, and it is impossible to achieve them overnight.
Back in 2011, China created the CJ-1000A project"cj"That's it"Yangtze River", at the same time,"c"It also has the meaning of Chinese initials"j"It is the meaning of the Chinese initials"j"It is the meaning of the Chinese initialsj"is the initials of Jetengine.
The CJ-1000A is under development under multiple meanings, and the advent of the CJ-1000A represents the development of China's independent commercial aviation power system.
If the ** taken by the netizen is indeed CJ-1000A is being tested for flight transportation, then COMAC's C919 is also expected to achieve engine localization in the future.
At present, the C919 is carrying foreign aircraft, but this is only a stopgap measure, because the development cycle of aero engines is often longer than that of aircraft, and it requires the efforts of generation after generation.
Therefore, there is no need to be discouraged when the domestic engine cannot be equipped with a domestic aircraft for the time being, and after the CJ-1000A engine completes the follow-up plus flight test verification, I believe that everything can be as desired.
What needs to be done now is to let more C919 delivery to the market, and COMAC will enhance the ability of C919 and achieve a certain influence in the market, such as the arrival of domestic engines, which can promote CJ-1000A to the world in a short period of time, so that the world can see the style of China's large aircraft and Chinese engines.
