Comments: Chinese domestic aircraft rushing to the clouds of the Yunxiao key parts are

The success of domestic medium -sized aircraft commercial flight virgins, which is once again proved that China ’s rise is once again proved that China’ s rise, Chinese people are inspiring and international attention.From the project to the first flight, after 16 years, the C919 medium -sized aircraft has independent intellectual property rights, but according to the proportion, there are still about 40 % of key components relying on foreign manufacturers.As a result, the results will be achieved soon, and they will be developed to design and develop larger aircraft.The road of self -developing key technologies is necessary and can be successful, and other industries must also check the omissions.

The high -speed rail currently shuttled on the land, technology leads the world, but over 9.6 million square kilometers, frequent large and small planes are Boeing and European air buses from the United States. When can it achieve domestic production?The plane dream lingers in the hearts of the people for decades.Domestic aircraft dreams are the Douglas Airlines that have been merged with Boeing in 1986 from the "Begging for Susp". In 1986, a small parts were embedded in Shanghai.Embedded and aircraft seats and other production qualification certificates, but the total output value is less than the zero -selling price of an aircraft.In 2008, the bus buses were installed in Tianjin's factories in Tianjin. This year, French President Macron visited China and announced the establishment of the second assembly production line, but it was all installed or production small components.European and American companies are willing to give up a small part of aircraft manufacturing to China. It is the result of the strength of the Chinese aviation market from forming to gradually expanding.

A coin has two sides. Foreign airlines gradually increased more production procedures to China. Instead, some people in the aviation industry "complacent" and continue to believe that it is better to buy an airplane."" ".From scratch, the aircraft is indeed "small as small as small". Even if the C919 aircraft that is currently engaged in commercial operations, the selling price is only half of similar products in the United States and Europe, and most of the costs are used to pay for key components."Flying the head of the head".However, the success of the domestic aircraft COSCO has made two aircraft manufacturers who monopolized international markets.The capital will slip significantly. In 2018, Boeing's annual revenue, 22%came from the Chinese market. In 2019, the water plugged in water fell to 7%, and in 2022, it fell to 0.25%of the importance.In the future, domestic aircraft can replace similar foreign products. European and American aircraft manufacturers occupy the share in the Chinese market. The gradual decline in the Chinese market will inevitably become a trend, and the profits of domestic aircraft manufacturers will gradually expand.

It is not easy to realize the dream of domestic aircraft. In the past, the Soviet aircraft species had carried out "transportation" short -distance and short -distance transport aircraft. Because the technology was not closed, it also stopped the air crash and stopped.Since then, do you want to develop large aircraft disputes? Even if you want to do it, do you want to develop components or design large planes first, and there are controversy. In the end, it is impossible to wait until all parts can be made in the domestically produced.In 2007, he was determined to engage in large planes, invest in resources for design, and build your own parts and components within the power of the power. First, the foreign parts who do not pass the technology and the large aircraft are put into the market in batches, which can naturally drive the research and development and production of key parts.At present, it is reported that domestic large aircraft engines will be successfully developed within a few years, and there will be no fake hands to others.

C919 Domestic aircraft still has 40 % of key components relying on foreign supply (about 60 % of the price calculations), including engines, electricity, flight control, fuel hydraulic systemPolitical factors affect the stability of supply, because in business talks, the higher the output of C919 aircraft, the more they have business, and they are convinced that with China's research and development capabilities, they can develop alternative products sooner or later. Suppliers can make money.It is always a problem that cannot be avoided, whether it depends on European and American countries that have potential contradictions with China, or relatively friendly Russia.

C919 is a medium -sized aircraft with 150 to 180 seats (more than 150 seats in mainland China are large planes, and the world is used to 300 or more large aircraft). At present, 300 remote C929 is currently in the research and development stage.It turned out to be developed with Russia. After all, Russian aerospace technology has a deep foundation, and some strengths can make up for the deficiencies of China. However, due to the deterioration of Russia and the West, even if Russia is successful, Russia cannot sell to Europe and make a profit from it.With the help of foreign forces, the country's great artifact has always been unreliable. This is the same as the manufacture of aircraft, as well as in other pillar industries.

Yesterday's first flight between Shanghai and Beijing, the report said that the number of votes was very considerable, indicating that Chinese people voted with their feet and supported domestic aircraft with their actions.At present, C919 has more than 1,000 orders, 34 of which come from foreign countries, with a total output value of 500 billion yuan, and the market potential is unlimited.The key factor of domestic aircraft obtained a foreign aircraft permit is the safety indicator. The longer the business operation time of the C919 is favorable, and the quality of other domestic aircraft can also be proved.At present, 80 ARJ21 domestic support aircraft, which have been delivered to the use of 100 aircraft, have been in business for many years. Last year, it was also delivered to Indonesia for the first time in Indonesia. I believe that domestic orders will come one after another.

Domestic small and medium -sized aircraft soaring the motherland will become more and more in the future. A larger aircraft will fly over the five continents, which will also be expected.The dream of domestic aircraft is part of the Chinese rejuvenation dream. It is worth proud. The country should invest more for the key technologies for research and development of scientific researchers to develop other countries in other countries. It uses real technology power to explain that the rise of China can benefit the Chinese people and share internationally.
