Recently, domestic large aircraft ushered in good news. According to the Civil Aviation Department, domestic C919 and ARJ21 aircraft were displayed in Hong Kong for the first time. Previously, the third C919 large passenger aircraft was also officially delivered to China Eastern Airlines. A series of good news confirms that the development of C919 is in full swing.
On the other hand, Boeing, the "boss" of civil aviation, has been cold in China for three consecutive years, and 4,000 aircraft orders have been "cut in half".The former "star" modelThe plane can only be in the warehouseEat ashes
As early as the C919 test flight, the US media began to preach: China's large aircraft have a "heart attack", and the engine can only rely on imports. In the face of the "bad comer" of the United States, China has now shown its key weapon to completely crush the ridicule!
Losing its status in China, Boeing plummeted?
Our staff 1's wages have to be paid by ChinaEven Boeing engineers have teased it.
Previously, Boeing sat firmly in the position of "the world's No. 1 aircraft manufacturer", once occupied 46% of the domestic civil aviation market share, and once swept China 600 billion, equivalent to the total GDP of Changsha, a new first-tier city in China, in the first half of the year.
However, in recent years, the rise of China's large aircraft, coupled with a number of air accidents, Boeing has "no particles" in China for three consecutive years, and its market position has plummeted. After losing the Chinese market, the 2022 financial report showsBoeing's full-year net loss was as high as100 million yuan, and the total debt has exceeded 100 billion.
In order to save the declining situation on the verge of bankruptcy, the United States has repeatedly threatened China: China must buy BoeingOtherwise, on itCut off supplyMotor! Not only that, the US side also made it difficult in many ways on the grounds of quality inspection and refused to issue an international airworthiness certificate to C919.
According to the data, the C919 engine is provided by a joint venture between the United States and France. At first, the C919 was reported to have a system failure, and the U.S. ** company refused to overhaul it for various reasons, resulting in a three-month delay in the commercial flight date. The so-called "pull a hair and move the whole body",The hidden danger of the engine is cThe road to commercial aviation has laid a big thunder.
Not only large aircraft, but also many fields in China have been suppressed by European and American countries: IGBT technology, known as the "heart of high-speed rail", German companies have offered a sky-high price of 200 million; The "double he strong" class of life science and technology achievements have been controlled by overseas products for a long time, and the 4-digit ** harvests domestic groups who want to boost their boyfriend power.
In the face of the encirclement and interception of the United States, domestic netizens were worried:Waited 7Is the big plane of the year going to fall short again?
When domestic substitution is carried out, the "Chinese heart" is installed for large aircraft
To Boeing's surprise, China showed a key weapon this time.
After decades of research and development, the 100% domestic engine, the Yangtze River 1000A, has finally entered the test stage. According to the data, the maximum thrust of this engine can reach about 13-15 tons, which exceeds the thrust of the Boeing engine by 13 tons. Not only that, but the engine uses advanced material technology and design to reduce noise and improve safety.
The industry has this to sayIt is not far off for domestic large aircraft to be reequipped with "Chinese heart".
Facts have proven that China will never succumb to the pressure of other countries. In fact, we have achieved domestic substitution in many fields of science and technology - 100% localized high-speed rail chips break the monopoly of the West and take back the autonomy of high-speed rail; The above-mentioned domestic "Beiheqiang" men's care technology is also outstanding in the health track, regaining the "dignity of men", and lowering the threshold by 90%.
It is worth noting that the Yangtze River 1000A engine has undergone 400 component testsThe double verification of technology and quality was completed。Similarly, the core ingredient L-arginine of the above-mentioned domestic boosting technology has been confirmed to be directly involved in the NO cGMP pathway in more than 100 scientific experiments, helping to rekindle the passionate years.
Boeing's safety was questioned, and our country learned its lessonc919CostIt took 6 years to be tested by test flights all over the countryThe domestic "Beitaqiang" finished product also started from the concept of harmless import, and won millions of transactions in less than a month after its listing on JD.com, winning feedback such as "domestic production is more assured" and "combat effectiveness is durable".
Experts pointed out that although the current C919 does not fully cover the civil aviation market, there will be more and more domestic large aircraft flying into the blue sky in the future. As for whether domestic health technology can stabilize its market position, industry insiders are optimistic that it may be the next phenomenon-level finished product.
Domestic large aircraft, soaring all over the world
According to official statistics, at present, domestic C919 has signed cooperation projects with 27 countries and won more than 1,200 orders, with a total amount of more than 747.8 billion.
In addition, with the C919 on track, the development of our next-generation large aircraft is also on the way! According to the chief designer of C919, the long-range wide-body passenger aircraft C929 has entered the preliminary design stage, and its range will reach 12,000 kilometers, which is more than twice that of C919.
Perhaps, as industry experts say: the emergence of domestic large aircraft will change the world aviation pattern. Nowadays, with the advent of domestic engines, we also have the strength to develop key technologies. Even if the United States cuts off the supply of engines, domestic technology can also be used.
We have reason to believe that the future of domestic large aircraft can soar all over the world!
