Super military empire

Chapter 669: There are too many failures in Yun Ten (Greatly increased 2/5 for driden)

silence.

Even the entire air solidified.

This is one of the most serious problems facing the large aircraft project!

The four JT-3D engines imported from the United States were originally only used as spares. The large aircraft was initially prepared to use the domestic turbofan eight.

As a result, the turbofan eight succeeded, but it was not suitable for the use of large aircraft. The leaders of the large aircraft factory discussed and decided that the four spare engines were finally installed on the second prototype for flight test, so that Yunshifei was allowed to fly. Up.

This is a problem that everyone is unwilling to face. Whether it is the personnel of the 708 Institute responsible for designing the large aircraft or the related personnel of the 5703 factory responsible for the production of large aircraft, they are not engaged in engines!

The domestic package is not available, and they have no choice.

"Director Liu, if the country can provide practical engines, our aircraft can still fly!" Ma Fengshan has never contacted Liu Yijiu, but Liu Yijiu has sent people to contact him quite a few times. This is the first in China. No one wants to offend a unit that is willing to continue to inject funds into the big airplane, and it is a very wealthy unit.

What's more, Liu Yijiu was not dissatisfied with this project, but raised the most difficult question.

If the engine problem is not solved, even if the entire large aircraft continues, once the supply channel is cut off abroad, these aircraft will still not be able to fly.At that time, if foreign countries want to use this threat, it will be difficult to solve the problem.

"Director Liu, I don't think there is anything to worry about. Even if there are no Americans, we can introduce British bass engines, especially now that the domestic production technology of bass engines is introduced..." For Liu Yijiu, he won the vortex. Yan Ruyun is not clear about the progress of the Fanba team.

In Qin Fei, the technology of the bass engine, Qin Fei's people are also hesitating.

"Bass engine? According to what I know, localization is simply not possible. So far, no successful samples have been seen..." Liu Yijiu sneered.

"Isn't there our turbofan ten?" Wang Shunyi felt that Liu Yijiu was abnormal.

The whole person is like taking gunpowder. If he continues like this, there is no need to talk about it.The Ninth Academy is honestly hiding in the mountains and studying its own technology. How good is this. Why should you come out and do these things that are thankless and waste a lot of money?

Looking at Li Rui beside Liu Yijiu, Li Rui lowered his head, making Wang Shunyi even more confused.

Liu Yijiu is not a person who can affect things at work because of personal matters.

"Yes, Director Liu, I heard from Director Zheng Hao that the research and development of the turbofan 10 team of the 611 Institute has made breakthrough progress. The first engine sample has been trial-produced, and the test run is underway. If the turbofan 10 test runs It's over, no problem. I don’t think the engine will be a hindrance to our big plane going to the sky! Even then, we won’t worry about the safety of the big plane because of heart disease..." Hearing Wang Shunyi’s words, Yan Ruyun quickly agreed. .

The Ninth Institute took over the research work of turbofan eight a few years ago, and further studied turbofan ten on the basis of turbofan eight, and even samples came out, or Liu Yijiu was because they used a spare engine. Isn't the turbofan angry?

"Director Liu, during our development process, there are indeed many problems, but these problems are not impossible to solve, and we have solved all the problems that have arisen. Please rest assured about this. We are all engaged in technology. Yes, there will never be any negligence in the safety performance of the aircraft..." Ma Fengshan also knows that because of the domestic industrial base, many things have adopted native methods.

Don't worry about the safety performance, this is normal.

However, the test flight has just begun!Airplanes are nothing else. Test flights must be conducted, and it will take a long time and a lot of test flights to enter the market. Otherwise, once there is a problem, it is a big deal!

"As for the 58 imported finished parts you are referring to, if these can be kept up with the domestic materials and production process, everything will not be a problem. When I contacted the staff of the Ninth Institute, I also knew that if the Ninth Institute can It provides avionics systems, radars, even large presses, blasting welding technology, etc. These 58 imported finished parts can no longer be imported from abroad, and absolutely 100% domestically..." Ma Fengshan cleverly pushed the matter to the Ninth Institute Body.

The Ninth Institute has to intervene in the large aircraft plan not only because the Ninth Institute can provide a large amount of funds, but also because the Ninth Institute can provide strong technical support.

Technical support is what the big aircraft team needs most.

They are designing airplanes, not solving the problems that arise during the production of various parts.

After all, they are not experts in mechanical manufacturing, production processes, and even materials.

Liu Yijiu heard the words of Ma Fengshan, the chief designer who he respected, overcoming strength with softness. He couldn't help but smile, and immediately thought, it seemed that these were not the fault of these people.

The country's industrial foundation is poor, and he feels that he is bound to do everything. All of this cannot be a reason for his irritability.

Only by working hard to solve these problems, solving them step by step, so that the country gradually develops and becomes stronger in the process of solving these problems, is what he should do.He is irritable, purely because he is a little eager.

Engaging in technology is definitely not as simple as a dinner party.

You have to eat one bite at a time, and you have to walk step by step.

Even the United States and the Soviet Union did not develop and become strong in a short span of ten or twenty years.If it hadn’t been for the American financial crisis that the Soviet Union had almost emptied the entire American industrial base, and Hitler had attacked the entire Soviet Union with absolute power, which made their industry rapidly develop and grow during the war, the Soviet Union could not have competed with the American imperialists. strength.

And the US emperor, the development time is longer.Although it is not as profound as the history of an old industrial power such as the United Kingdom, the American industry has also developed for more than two hundred years to achieve today's achievements!

The Republic can spend less than half of the time on industrial development in just 30 years. With the current foundation, it is not bad. There is no need to complain or be upset.

"Lao Ma, I believe this can be done. What if these problems cannot be solved in a short time?" Although Liu Yijiu's attitude has improved a lot, the problem is still acute.

"If there is no way to solve these problems, we can still only adopt the current method and continue to import key parts and components in the process of continuous development. And get more data and experience from more test flights, and discover more The problem..." The current situation has turned into a separate confrontation between Liu Yijiu and Ma Fengshan, the chief designer of Yunshi.

Yan Ruyun was speechless. They just wanted to get the funds to assemble the remaining three prototypes. As for that?

Only 30 million is enough.

Immediately he was very dissatisfied and said to Liu Yijiu, a young man who was just looking for faults: "Director Liu, most of the remaining three prototypes have already been produced. All you need to do is to assemble these parts into a finished aircraft. That's it."

"Director Yan, things are not so simple, right?" Wang Shunyi understood what Liu Yijiu said.

At the beginning, Liu Yijiu didn't mention many of the defects of the big plane in order to win their consent.If the Shanghai Municipal Government and the current development status of the large aircraft continue, the entire large aircraft may not even be able to promote the entire domestic industrial system as they expected.

Now, Liu Yijiu is forcing the other party to hand over the management power to the Ninth Academy, and let the big aircraft develop in accordance with the Ninth Academy's ideas and promote the country's industrial system.

After all, they did not intend to guarantee no loss from the beginning, and they plan to invest at least two billion in large aircraft in the next ten years!

No one hopes that this 2 billion investment will be in vain!

Wang Shunyi’s demeanor was very serious. When everyone looked at him, he continued: “According to the technical data we have obtained, your first prototype for static pressure testing has been used since October 1976. More than 1,650 various faults were found in the row, and there were riveting quality problems, such as small rivets instead of large rivets, studs not riveted, missing rivets, etc.; important force-bearing parts were forced to be assembled; components were not coordinated, etc....especially the two wings There were 127 failures on the No. 10 rib of the important stressed part..."

This was only the first plane that did not go to the sky.

When Wang Shunyi said this, he did not end, but continued: "In the first quarter of 1978, the major aircraft factory conducted a quality inspection on the second prototype for flight test. Only the quality of the riveted parts was a problem, and 5312 appeared. Among them, there are 127 of the major quality problems, and a total of 825 pieces of scrapped and updated parts. These data are not wrong, right? Moreover, you did not completely report these data to the Ministry of Aviation Industry..."

These data are all so detailed and accurate, and everyone here is the main management unit of the entire large aircraft project.

Moreover, the Shanghai Municipal Government believes that this is the project they are in charge of. Even if it is not reported to the Ministry of Aviation Industry, as long as the problem is solved and the plane finally flies, there is no problem.

But I didn't expect that the people in the Ninth Hospital didn't know where they got the data!

Moreover, now that these data are taken out, they have no way to object.

There were problems in the first test, and the second was not improved. Instead, there were more. If it were not for a comprehensive and repeated investigation, it would be impossible to find out, and it might even be clear as soon as the plane flies!
