Please, know friend please, question 5 about aircraft development

Because our own technology is not as good as other countries in some areas, we can learn some of the things we want by working with them! That's how I understand it!

There is no way to do this. Although in recent years, China has advocated independent research and development of large aircraft and other projects. However, there are still many key technologies in China's large aircraft and other projects that are not yet mature, or are still in their infancy.

For example, in recent years, China has imported products and technologies such as engines and radars from Russia and other countries. Even if those countries claim that the products they export are the most advanced in their own countries, in fact, the discerning people know that they have reservations about their technology, because if they give all their most advanced technology to China, then the contract may be terminated after a while.

Because China has learned this technology, it will not continue to order. Therefore, because of all these reasons, China cannot afford to manufacture it completely, and can only try to cooperate with it.

Because China has always been a model of cooperation + absorption + innovation for high-end technology, such benefits are obvious, our country has made too many mistakes behind closed doors, isn't it good to do so?

Since ancient times, human beings have never stopped adventuring and exploring in order to see what is going on in the sky. There is a dream that the Chinese have been chasing for half a century; There is a love that continues for five generations of aviation people. More than nine years of tackling key problems, behind which is hard work and silent hard work; Nearly 10,000 people have developed it, and the difficulties can be imagined.

Since the Y-10 project was established in 1970, and then to the successful first flight of China's first mainline aircraft with international mainstream standards and completely independent intellectual property rights, China's "big aircraft dream" has finally come true after 47 years.

Today's C919 large passenger aircraft 104 aircraft first flight successfully Today (August 1), China's self-developed C919 large passenger aircraft 104 aircraft (the fourth) completed the first test flight at Shanghai Pudong International Airport, marking the total number of domestic C919 large passenger aircraft that can be put into test flight work to reach four, and the test flight work will be further accelerated.

Let's review the "legendary route" of the first three C919s, the first domestic large passenger aircraft C919, and the first flight.

At 15:19 on May 5, 2017, Beijing time, China's self-developed new generation of jet trunk airliner C919 (numbered 10101) completed its first flight and successfully landed at Shanghai Pudong International Airport. On this day, Shanghai Pudong Airport attracted the attention of hundreds of millions of people. On this day, China's first C919 large passenger aircraft developed in accordance with international standards and with independent intellectual property rights made its first flight.

Taxiing, accelerating, take-off, ......The passenger plane carrying the glory and dreams of several generations of Chinese took off and soared freely in the blue sky of the motherland.

At 11:07 a.m. Beijing time on December 28, 2018, the third domestic large passenger aircraft C919 took off from the fourth runway of Shanghai Pudong International Airport and began to complete its first flight. At 12:45 p.m., after 1 hour and 38 minutes of flight, the third domestic large passenger aircraft C919 landed at Shanghai Pudong International Airport and completed its first flight. During this flight, 103 C919 aircraft completed 21 test points.

In fact, it can be manufactured now, and the successful completion of the test flight of the self-developed large passenger aircraft means that it is fast.

The chronic damage of sunlight to the body is frightening, but the acute damage is also very disturbing.

Now that the test flight has been successfully completed, it will definitely be ready to use it immediately.

The successful completion of the test flight of the self-developed large passenger aircraft means that it is fast.

Soon, in fact, it can be made now, but some have not been tested yet.

After all, the large passenger aircraft independently developed by China successfully completed the test flight, which shows that it is very soon.

Test flights mean fast.

How can you ask me about this, go ask the country.

It's almost there. As long as the research comes out, it will be popularized very quickly.

(1) Human ground activities are affected by the topography and need to open roads, trek through mountains and rivers, which hinder the desire of human beings to move at high speed without barriers, and the invention of airplanes solves these problems.

2) The invention of the automobile solved the drawbacks of cumbersome and slow transportation of traditional carriages and horses.

3) The invention of the light bulb solved the need for a bright, stable light source at night.

On December 17, 1903, the first aircraft built by the Wright brothers, the Flyer 1, successfully flew in North Carolina, USA.
