What is the international technical level of domestic large aircraft C9 19?

In modern society, scientific and technological strength can truly reflect the true strength of a country. Take the United States for example, it has high-end technology in almost all fields, so it can achieve dollar hegemony, which also makes many countries very helpless, but they don't have high-end technology. Therefore, over the years, China has gained a lot. In the past few years, the c9 19 large aircraft independently produced by China was successfully tested and received a large number of orders. Then there is the domestic large aircraft C965438+. It can be compared with the old Boeing and Airbus, two very popular planes in the world, and it can be said that it has been at the forefront of mastering aircraft technology in the world.

When the new China was first established, everything needed to be improved. At this time, the country does not have much money to improve, so many people think that building is better than buying and renting is better than renting. So the planes we travel are rented by others, and so are many instruments and equipment. This is a wrong view. Just like mobile phone chips, Huawei was banned by the United States, and it was crazy to use the power of one country to ban a private enterprise. We can see how important technology is. Flying is the dream of the Chinese nation for thousands of years, and we realized it a few years ago. The c9 19 aircraft independently produced by China can compete with Boeing and Airbus, even surpass them in many aspects. There are also many orders in the world, many of which are already in flight. ?

Over the years, China's scientific and technological strength has been continuously enhanced, which we have witnessed with our own eyes. If it is a mobile phone, many people would say that Android phone is very stuck and Apple phone is very smooth ten years ago, but now the two phones are the same price, and there is no card behavior. This is the progress of science and technology. Besides, China has made great progress in ophthalmology, medicine and space flight, especially the Beidou navigation system, which is no longer allowed for us. The blind man in the sky? . ?

Now, apart from airplanes, China's high-speed rail ranks first in the world, and its speed will not be much slower than that of airplanes.
