C919 can not be ignored, the domestic large aircraft Spring Festival has emerged, and the United States 737MAX9 may take off again.
The Spring Festival is approaching,"Spring Festival"The topic is once again at the top of the top search lists. But unlike in the past, this time people pay more attention to the domestic large aircraft C919.
The news that four large domestic aircraft have joined the Spring Festival train has made the Chinese people excited. After all, for a long time, although China has been a major civil aviation country, strictly speaking, it is not a civil aviation power.
In the past, the global civil aviation market was evenly divided between the two giants, Airbus and Boeing. Although there are also some civil aviation companies active on the world stage, compared with these two giants, both in terms of sales and sales, they are slightly inferior. With the launch of COMAC C919, many people**, the hegemony of the two giants in the global civil aviation market will be broken.
It is precisely because of the emergence of China's commercial airliner C919 that the United States felt threatened and did not hesitate to return to the 737MZxx9, which had frequent safety problems. In fact, soon after the success of the C919 commercial flight, Europe and the United States imposed a series of restrictions on the development of China's civil aviation. So, what are the safety risks of the 737max9 go-around? Why does the domestic C919 make them feel threatened?
with"Spring Festival"With the arrival of China Eastern Airlines, four C919 domestic large aircraft were also officially put into operation. The news of their first flight to Chengdu Tianfu International Airport has attracted widespread attention, after all, it means that China's domestic aircraft is officially in civil aviation service.
On January 26, 2024, the first day of the Spring Festival, China Eastern Airlines rolled off the assembly line with four domestically produced C919 aircraft, which will carry 10 flights on Shanghai-Chengdu, Beijing-Shanghai and other routes, transporting a total of 1,274 passengers. The news of C919's departure for the Spring Festival not only shows that the domestic large aircraft has taken a big step forward in commercial operation, but also means that China's self-developed large aircraft has been affirmed by the market.
Many people have heard of the C919, but most of them only know that it is an aircraft independently developed by China's civil aviation. Previously, some so-called experts and aircraft enthusiasts mistakenly believed that the C919 belonged to an assembled aircraft. In fact, this is a very arrogant and biased misunderstanding, because commercial aircraft do not have to be 100% localized.
According to the data published by the C919, the positioning rate of the aircraft has reached 60%. The positioning rate of the famous Airbus and Boeing family aircraft is almost exactly the same as that of the C919.
Of course, there's nothing wrong with seeking full localization of the technology, but it takes time to develop. The so-called assembly is often the first step in the first stage of development, and the ability to build a world-class aircraft is enough to better promote the development of subsequent subsystems.
The development of independent scientific research and the development of large aircraft, the most important of which is the aero engine. At present, European and American countries have their own aero engines, therefore, it is necessary for China to lead the development of civil aviation in the process of engine technology development.
At present, although the national C919 aircraft supporting the aero engine is LEAP-1C, China's scientific researchers have been familiar with the relevant technology and have developed their own CJ1000A engine. It is reported that the engine has been successfully tested on the aerial test platform of 20 trailer transport aircraft, and it will be perfected within two years.
Today, the fuselage, nose and other components of the C919 have been completely localized, and the flight control, landing gear, and lifting system are basically domestic and foreign joint ventures. Those who mistakenly believe that the C919 is an assembly aircraft, it is because of these joint ventures that the C919 is created.
In fact, the production of the joint venture itself is a learning process, which allows us to better train our own engineers. Learning foreign advanced technology, rather than working behind closed doors, has played a positive role in promoting the localization of the future.
With the continuous accumulation of C919 flight hours, its recognition in the civil aviation market will become higher and higher. You must know that the C919 domestic aircraft, Airbus and Boeing belong to a category of civil aircraft, and it is not a few people think that the performance of assembled aircraft is backward.
In conclusion, more than 10 years ago, the C919 finally entered the commercial flight stage in our country. The development of China's civil aviation has injected new vitality, and at the same time, it also marks the great potential of China's aviation industry in scientific and technological innovation. But it is precisely because of its potential that the United States and Europe feel threatened by their position.
On January 5 of this year, Alaska Airlines in the United States took place"Thanksgiving door"After the incident, the Boeing 737 MAX9 was in the public spotlight. The incident has attracted widespread attention not only in the United States, but also in countries around the world.
In fact, the controversial hatch opening is a false door, i.e. this knowledge of the door, which simulates the shape of the hatch, belongs to a door sealing device. Its main role is to cover the excess holes above the aircraft to reduce the weight of the aircraft and also increase the flexibility of the cabin.
Obviously, the problem is not with a single aircraft, but with a safety flaw in the quality control system of the entire Boeing family of aircraft. Add to that the fact that the Boeing family has relied on the United States for a number of accidents in recent years, and the constant bad news has destroyed the reputation that Boeing has built up in the past.
Faced with such a serious security risk, the United States first ordered a global grounding of the 737MAX8. Immediately afterwards, the quality problem of 737max9 caught the United States off guard again, and the facts are already very clear, even if you want to quibble, you can't escape the blame of **.
Therefore, for this series of aircraft, the United States not only restricted flights before, but also clearly stipulated that production could not be increased. After all, as mentioned earlier, there have been a number of serious air crashes on Boeing 737 series aircraft in recent years, which have been questioned and complained about by the whole world. If you want to stop fermenting, of course, you have to take action to solve the problem.
But just as the U.S. was restricting increased aircraft production, United Airlines resumed flights of the 737 Max9 family of aircraft. In addition to this, Copa Airlines and Alaska Airlines have also announced the resumption of flights on this aircraft.
When ** has not been completely suppressed, it is never wise to make such a choice. However, the United States has never been willing to do anything unfavorable to itself, and the reason for this is that China already has its own large domestically produced aircraft. In order to keep its position in this area from being hit, it is not surprising that the United States made such a choice.
Of course, this is not the first time that Europe and the United States have restricted Chinese aviation in the process of development, after the successful commercial flight of the domestic C919, Europe and the United States have been tightly tied together, and continue to make negative comments. If you want to buy a big plane, you should buy it directly from Boeing.
As the saying goes, you can't wake up a person who is sleeping, whether it is a person who denigrates national aircraft experts, or a person who continues to introduce various policies to restrict China's large aircraft, cannot wake up a person who is sleeping.
Curiously, after the successful commercial flight of the C919, both Boeing and Airbus congratulated. This may seem like a very generous gesture, but it backfired, with Europe and the United States imposing varying degrees of restrictions on the C919.
Europe and the United States have stated that they will not issue an airworthiness certificate for the C919, while it is known that the aircraft will only be able to perform flight operations on that flight if it is obtained. Without European and American airworthiness certificates, the C919 will not be able to fly commercially in the respective regions.
After the news broke, some Western ** proudly said that as long as China's large aircraft cannot obtain the airworthiness certification of European and American countries, it will be difficult to develop. But they have long forgotten that China is currently the world's largest consumer market, and the Chinese mainland market is enough to support the development of China's large aircraft.
China's huge market will not only support the development of the C919, but will also have an impact on Boeing and Airbus. You know, Boeing's own products have been criticized for a long time, and now they are proving to be hostile to China. All this will gradually weaken its advantages in the Chinese market and eventually lose its own development opportunities.
As the Chinese market continues to inject new vitality, the civil aviation industry is expected to usher in explosive growth in the next decade. In addition to economic support, China's scientific and technological development has also advanced by leaps and bounds in recent years.
Especially in terms of the advancement of intelligence, this technology can greatly promote the development of civil aviation. It can bring more convenience to consumers and make an indelible contribution to aircraft safety. These technologies can boost consumer confidence and ultimately boost the civil aviation industry.
In 2023, the country's tourism industry has exploded, and people's travel rates have skyrocketed, which is enough to illustrate this.
At present, China's aviation field is also open to foreign cooperation under the premise of adhering to independent innovation. This has played a positive role in promoting the development process of China's civil aviation industry, both technology and the entire industrial chain.
Although there is still a gap with some Western countries, this is more of a historical issue. It is believed that with the rapid development of China's civil aviation industry, it will attract the attention of the world in the future.
