The top ten aircraft projects originated from an inspection by the Chairman of the National Congress. He said at the time: "The industrial foundation of the Shanghai Stock Exchange is so good, can you build large aircraft!"

So the "7o8" project, which is what people call "Yun Ten", was launched in a hurry. It started to be developed in 1971 and was successfully tested in 198o.

Back then, the entire airport was crowded with people, and the engineering and technical personnel, retired old designers, and severely ill old engineers all cheered and burst into tears. They successfully flew at one time, just like the later "919".

This test-flight engineering aircraft has almost flown across the country. When Tibetan areas encountered natural disasters, it also undertakes the task of transporting materials. People in China are happy to believe that China finally has a large aircraft comparable to Boeing 7o7.

However.

What made Han Xuan difficult to understand was that "Yunshi" such a major project related to the national strategic strength and status did not even have an official document to decide to dismiss. After the task was completed, it was terminated without reason and could no longer hear about it.

When Han Xuan gave up his research plan, he was still young. When he saw the sarcastic reports full of ridicule and disdain in the Wall Street Journal, he was extremely shocked. Even if he knew that the same was true in his previous life, he still felt lost.

At that time, Western media paid great attention to China's large aircraft project. When the news of the flight came, many foreigners even re-examined China's industrial system with surprise. Whether it was imitation or patchwork, it was at least really made.

Yun Shi, which marked the future and hope of China Aviation Industry, was strangled and died in the cradle. The dark side of it has been circulating on the Internet in later generations. When he saw those latecomers who made remarks, he didn't know what kind of mood he would look at this matter. Han Xuan was heartbroken and disappointed.

Due to the miscarriage of Yunshi, the domestic large aircraft project has become blank again. In the next twenty years, trillions of funds will be spent on purchasing aircraft abroad.

Some people have said that foreign forces do not want China to build planes themselves, so they bribed some people, which made the plan shelved. Some people say that the project was cancelled because of the technology not being up to standard and the lack of market.

To be fair, Han Xuan believes that there must be interference from foreign forces in this. At least if he is engaged in the large aircraft manufacturing industry, he will not easily allow other manufacturers to rise, especially in a large population country like China, which means huge market potential.

From an objective perspective, there must be dark stories in the whole thing, but they are no longer known to outsiders. The influence of a few people is by no means enough to dismiss this major project that concerns the fate of the country.

"Mr. Wu, do you think the top ten aircraft really have fatal flaws of congenital deficiencies?"

Han Xuan asked Mr. Wu Zuoquan in front of him this question, saying that this problem has always existed in his heart from his previous life to this life. Now when he meets a party who has clear inside information, there is no way he can't understand it.

The old man nodded and replied: "Well, Yunshi's fuel consumption is high, and the materials science is not as advanced as it is now, resulting in the weight of the fuselage heavier than that of foreign products, and the noise in the cabin is also high, but these problems are not impossible to solve.

From the successful test flight on September 26, 198o, to the 1985 Yun-Ten flights, a total of 130 take-offs, a maximum voyage of 3,600 kilometers, a maximum voyage of 930 kilometers, and a maximum flight ceiling of 11,000 meters.

The cabin is arranged in the economy class with a maximum take-off weight of 110 tons, reaching the standard of large aircraft.

The most difficult part has passed at the beginning, and there are some small troubles left. As long as the funds are in place, they can definitely be overcome.

Now we use grade computers to simulate pneumatic layouts. At that time, we could only rely on experts to calculate and simulate them. We had two days off a month and worked at least twelve hours a day for the rest of our time. Then the project was gone and even the main information was searched by others. We never saw it again. No one knew where we went. Several old friends suffered from depression because of this.

But over the years, I have already thought about the dismissal of the top ten aircraft projects, perhaps the best choice under the historical conditions at that time."

Han Xuan was stunned and asked him: "Why do you say that?"

"Because our country's industrial system was very backward at that time.

It is several levels behind now. If you want to successfully develop it, it will never be solved by adding 30 million yuan. Half the test flight is completed, all the funds will be spent. It is likely that more than one billion, or even billions of RMB, can be invested to truly get it out.

Others may not know that various fault problems occurred during the test flight. Although they looked fine, they actually entered a very difficult process after the overall design plan came out.

Many things cannot be made in our country, such as the motivation. They are purchased from Boeing. In addition, many important parts are purchased from abroad, which makes the construction cost high and the maintenance cost greatly increases. No domestic airline is willing to buy Yunshen, thinking that it is better to spend money to buy than to make it yourself.

This cannot be blamed by those designers, but only by the fact that the Chinese industrial system could not keep up. When the country had just emerged from the turmoil, I reported to the supreme leader and told them what they needed to make planes, but the country could not get it, and important technology was blocked by the West.

Even if I persisted back then, the products I made could only be compared with the performance of the first generation of large aircraft abroad, so the project was quietly shelved. Now the Y-Shen aircraft is still in the warehouse of our Shanghai airplane manufacturing factory. I will occasionally go and see it."

"Oh, it's wrong.

What we lost is not just a product, but the technological development platform on which China Aerospace Industry relies on. It could not be done twenty years ago. As long as we keep that set of things, it may not be impossible now.

Unfortunately, all the hits were killed by one blow, wasting more than ten years of research results invested in the early stage. At that time, a complete large aircraft driving system should have been formed, and we must start over from the future.

Will the project be re-established? I think it is definitely not. People already believe that large aircraft cannot be built in China, because the confidence in flying aircraft was lost. How many people's hearts are cold? With the power of a country, the money investment is worth it.

The past mistakes now require you to pay for this. Now, purchasing aircraft from abroad will be the same in the next ten years. You will be in vain to send money to Boeing and Airbus’ pockets to support many people.”

"Who said no, the entire project team was disintegrated. Another deputy factory director except me, patted his butt and walked away, and took his little immigrant to Austria. He was not upset.

Leave Lao Ma and I. Every day, I face Yun Shidai, and I seem to be unable to control my legs. I always want to go and take a look, wait for the country to invest again and design again. Unfortunately, Lao Ma only waited for a few years and left. Now I am unlucky, and urged him to continue driving..."

When Director Wu said this, his eyes were red, and he raised his arms and wiped them with his sleeves.

Although the country's decision was not wrong from the situation at that time, the researcher and management team's efforts over ten years were in vain. Even if they encounter such a thing, they cannot stand it.

What I am most sorry for is them. The youth and sweat of countless people were ruined by the 10th project, but they ended up in vain.

"I remember I once saw a saying in the book that evil and kindness are not pure enough, so it seems painful.

If you had patted your butt and left the plane factory back then, you might not have had these troubles.”

Han Xuan patted Director Wu on the shoulder to comfort him, feeling that the topic seemed to have gone astray, and continued to ask, "Is there anything wrong with me today?"

"Oh, I happened to see you coming to Yanjing from the newspaper. I heard that most of the shares of the British Rolls-Royce Aircraft Motive Company are in your hands, so I want to talk to you about purchasing aircraft motives."

"Why, your factory wants to build aircraft?"

"Some time ago, we cooperated with McDonald Aircraft Corporation of the United States to prepare for the production of md9o-aircraft. It was about to be acquired by Boeing, but the previous orders still counted. We will build two aircraft, so we want to purchase four cutting-edge motivations from your company."

Hearing the word "the most cutting-edge", Han Xuan stared at Director Wu with a strange look.

He had long known the "copycat" skills of the Chinese people. If the materials and technology were not up to standard, maybe even the fifth-generation F22 Raptor fighter that flew last year would be copied with a tape measure. There were countless motives for being tragically injured. He made great progress all the way, which greatly promoted the development of the motherland's aerospace industry.

Now, Han Xuan has the strange illusion that his company's products are also targeted. He looked at Director Wu's sincere eyes on the opposite side, and asked him with caution: "What kind of motivation?"

“Trentha 8oo series.

I know that the business is too uncertain and will expand production capacity in the future. What do you think?"

Small and medium-sized passenger aircraft are enough to use the Trent 7oo series. Boeing 777's tonnage is just right. Han Xuan still knows this, and he believes it even more. They have set their eyes on the latest technology of their company, and their expressions are immediately disappointed.
