"Mr. Wu, do you think that the top ten planes really have the fatal flaw of congenital insufficiency?"

Han Xuan asked Mr. Wu Zuoquan in front of him and said that this question has always existed in his heart from his previous life to this life, and now when he meets a party who knows the inside story, how can he not understand the reason.

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

From the first successful test flight on September 26, 1980, to 1985, Yun-10 flew a total of 130 takeoffs and landings, with a maximum range of 3,600 kilometers, a maximum speed of 930 kilometers per hour, and a maximum flight ceiling of 11,000 kilometers.

The cabin is arranged according to 178 seats in economy class and 124 seats in mixed class, with a maximum take-off weight of 110 tons, which meets the standard of a large aircraft.

The hardest part has already passed, and there are some small troubles left, which can definitely be overcome as long as the funds are in place.

Now they use supercomputers to simulate the aerodynamic layout, at that time they can only rely on experts to calculate and simulate, two days off a month, and the rest of the time to work at least twelve hours a day, and then the project is gone, even the main information has been searched by others, and then I have never seen it again, no one knows where I went, and several old friends have depression because of this.

However, over the years, I have thought that the launch of the top ten aircraft projects may be the best choice under the historical conditions at that time. ”

Han Xuan was stunned for a moment and asked him, "Why do you say that?" ”

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

It is several grades behind the current level, and if we want to successfully develop it, it is by no means possible to solve it by adding 30 million yuan, and halfway through the test flight, all the funds will be spent, and it is very likely that we will have to invest more than 1 billion or even billions of yuan to really get it out.

Others may not know that there were various malfunctions during the test flight, although it looked fine on the outside, but in fact, after the general design came out, it entered a very difficult process.

Many things can not be made in our country, such as the engine, which is purchased from Boeing, and many important parts and components are also purchased from abroad, which makes the cost high at the same time, and the maintenance cost is also greatly increased.

This can't be blamed on those designers, only the Chinese industrial system can't keep up, when the country just came out of the turmoil, when I reported to the top leaders, I told them what they needed to make airplanes, but the country couldn't get it, and important technology was blocked by the West.

Even if it persisted in that year, the products manufactured could only be compared with the performance of the first generation of large foreign aircraft, so the project was quietly shelved, and now the Yun-10 aircraft is still in the warehouse of our Shanghai Aircraft Factory, and occasionally I will go to see it......"

"Oh, that's wrong.

What has been lost is not just a product, but the technology development platform on which the Huaxia aerospace industry depends, which could not be done 20 years ago, as long as that set of things is kept, it may not be impossible now.

It's a pity that all of them were killed with a stick, wasting more than ten years of research results invested in the early stage, and a perfect large aircraft development system should have been formed at that time, and we have to start all over again in the future.

Will the project be re-established? I don't think it will be, people already think that the country can't build a big plane, because the confidence in the development of the aircraft has been lost, and how many people's hearts have been chilled, with the strength of a country, the money is worth it.

The mistakes of the past are now to be paid for, and now the purchase of aircraft from abroad will also be the same for more than a decade in the future, sending money to the pockets of Boeing and Airbus in vain to feed many people. ”

"Leave me and the old horse, every day in the face of Yun Shi in a daze, as if I can't control my legs, always want to take a look, waiting for the country to re-invest funds, the day when the design again comes, but unfortunately the old horse only waited for a few years, and then he left, and now I am left unlucky, urging the above to continue to develop......"

When Director Wu said this, his eyes were red, and he raised his arm to wipe it with his sleeve.

Although judging from the situation at that time, the country's decision was not wrong, but the hard work of more than ten years of hard work of the researchers and management was in vain, and they couldn't stand it personally.

The most sorry thing is that they are the youth and sweat of countless people, who were buried in the Yunshi project, but ended up in vain......

"I remember reading a sentence in a book that neither evil nor good is pure enough, so it seems painful.

If you had patted your ass and left the aircraft factory, you might not have had these troubles. ”

Han Xuan patted Director Wu on the shoulder to comfort him, feeling that the topic seemed to be off track, and continued to ask: "May I ask if there is something to come to me today?" ”

"Oh, I just happened to see the news of your coming to Yanjing in the newspaper, and I heard that the vast majority of the shares of Rolls-Royce Aircraft Engine Company in the United Kingdom are in your hands, so I want to talk to you about the purchase of aircraft engines."

"What, your factory wants to build an airplane?"

"Some time ago, I cooperated with McDonnell Douglas Aircraft Company in the United States to prepare for the production of MD90-30 aircraft, which is about to be acquired by Boeing, but the previous order is still counted, we will build two aircraft, so we want to purchase four cutting-edge engines from your company."

Hearing the word "cutting-edge", Han Xuan stared at Director Wu strangely.

If it weren't for the material technology, maybe even the fifth-generation F22 Raptor fighter that made its first flight last year would have been measured and copied with a tape measure.

Now, Han Xuan has a strange illusion that his company's products are also being targeted, looked at the sincere eyes of Director Wu on the opposite side, and asked him warily: "What kind of engine?" ”

"Trent 800 series.

I know the business is too small, but maybe we will expand our production capacity in the future, what do you think? ”

It is enough for small and medium-sized passenger aircraft to use the Trent 700 series, and the tonnage of the Boeing 777 is just 800......
