(The update in the past two days is a little less, originally said to return to Chengdu to update seriously, but I came back yesterday to find that Chengdu has been so hot that I can't code words just by wearing underwear, two fans blow against each other, sweat also keeps flowing, last night the two babies at home cried all night, and today I bought an air conditioner, but it took two days to install.) Pen | fun | pavilion www. ｂｉｑｕｇｅ。 info It's hot during the day, and there's no code word, and there's a power outage at night...... I'm sorry for you in the next two days. ）

Qiu Yue's identity, if he said anything, but the final result was not like this, it would affect the relationship between the Ninth Academy and the military, after all, the people of the Ninth Academy would definitely suspect that someone was obstructing it, just like when Yun Ten got off the horse, there were too many conspiracy theories.

Even, someone from the Civil Aviation Administration of China is clamoring that even if the Yun-10 is successfully developed, it will not buy the Yun-10 aircraft, and even, until now, the Yun-10 has not obtained the airworthiness certificate of the Civil Aviation Administration.

There are some problems in this, and the people of the Nine Courtyards are already very dissatisfied with this matter now.

"There's no need to say it's irrelevant. Yun 20 is just a basic platform, an early warning aircraft or something, and it can't be made in a short time. Everything we have needs to rely on ourselves to explore and study, and if we want to rely on the introduction from abroad, there is not much possibility at all, even if the international embargo has not begun to impose on us, it is impossible for us to obtain advanced technology...... "Liu Yijiu does not want to dwell on this matter anymore.

Qiu Yue can't do anything about this matter at all, even the old man and Long Yaohua and others are a little powerless, otherwise, Yun Ten is out, domestic civil airliners have a lot of demand, old planes like Trident are no longer usable, domestic aircraft, not to mention flying far, can not carry too many people.

With the liberalization of civil aviation's requirements for the identity of people who take planes, ordinary people can also take them, so that the civil aviation market has begun to develop, and the demand for large aircraft is getting bigger and bigger.

However, Yun Shi did not enter the eyes of the Civil Aviation Administration at all.

"The situation of Yun 20 is different from that of Yun 10, but based on the current flight situation of your Yun 10 over the years, I think you should continue to develop vigorously on Yun 10. It should be good to use as a trunk airliner, and after the Yun20 civilian version is studied, this aircraft can be modified and used as a regional airliner! Liu Yijiu didn't want to talk about Yun Shi, but Qiu Yue took the initiative to say it.

His words immediately made the eyes of Ma Fengshan and other technicians light up.

looked at the huge Yunshi next to him, then turned his head to Qiu Yue and asked excitedly, "Chief, does the central government have any new instructions for the Yunshi project?" ”

Liu Yijiu was also full of expectations, Qiu Yue would definitely not be groundless when he said this. These bigwigs above will never say anything that they are not sure of, otherwise it is that kind of ambiguous official language, Qiu Yue's words have been said to such an extent, obviously, it is the national high-level who has some ideas about the aircraft of Yun Shi.

Seeing everyone's expectation, Qiu Yue smiled helplessly, and then explained to everyone, "At present, it is only proposed that in order to support the development of the domestic aviation industry, you will fly around the country for ten days, and the Civil Aviation Administration has been negotiating with McDonnell Douglas in the United States, and now it is almost over." In the skies of our country, we cannot only fly large planes from abroad, but not our country's own large planes......"

"Really? In this way, does our Yun-10 have a chance to appear in the aviation market? Ma Fengshan and the other main persons in charge of the 10th project were so excited that tears were about to flow out at this time.

Yunshi has been engaged in it for almost 20 years until now.

The Ninth Academy has paid its own money and has been conducting various flight tests non-stop, and up to now, all the funds consumed have added up to at least more than 1.5 billion, but because of the obstruction of some people in the Civil Aviation Administration, the airworthiness certificate has not been obtained.

Qiu Yue said that if the central authorities have such an idea, it is natural that they must first solve the problem of airworthiness certificate.

"No one can say the specific situation now, besides, even if the central government is willing to vigorously support our large aircraft manufacturing industry, it must be on the basis of our civil aviation airworthiness certificate. All kinds of technologies must be fully mature, and all kinds of design flaws can be found. Liu Yijiu heard something from Qiu Yue's words.

The old man is selling himself a good thing.

If it weren't for the old man and others putting pressure on the Civil Aviation Administration, such a situation would not have occurred at all.

"Yes, Comrade Xiao Liu is right, it is necessary to solve these basic problems before it is possible to obtain orders. Several of our domestic airlines are currently operating at a loss, and they are all relying on state financial subsidies to purchase new aircraft, and the amount of funds required is not small. There is nothing wrong with the support of McDonnell Douglas because we can train a large number of skilled technicians in the process of working with them, and at the same time, our aircraft designers can learn their design ...... up close."

The co-production with McDonnell Douglas was initiated by the people at McDonnell Douglas, but in China, there are many people who support such a thing.

Because the Yunshi project was very political when it was established, many people thought that there were too many people who opposed the Yunshi and that there was a political purpose for getting off the horse, but in fact, only Liu Yijiu, who knew the specific situation in this era, knew about it.

Yun-10 has been developing until now, and it has taken several years longer than the time in history to completely dismount, with more than 5,000 sorties and more than 7,000 hours of flight time. While each flight was safe and trouble-free, only the research team knew how many design flaws they found during those flights.

It took an extra billion dollars to make the design really mature.

As for performance, it is actually much worse than the world's most advanced aircraft of the same type.

Otherwise, it would be impossible for Liu Yijiu to let the Ninth Academy continue to fund and support the continuous improvement of the project.

"In addition, civil airliners are different from military transport aircraft, and they have higher requirements for safety, because civil airliners fly every day, and even the flight time is relatively long every day, and each flight is carrying a large number of people......" Qiu Yue's words seem to have nothing to do with what he is saying now, but in fact, most of the people present can understand the subtext of these words.

Yun 10 does not have an airworthiness certificate, and this problem must be solved before we can say the next step.

After all, civil airliners are different from military transport aircraft, mainly used for the transportation of personnel, and the airworthiness certificate will be issued after the safety performance of the aircraft can be fully verified, which is a good thing for everyone.

Saying this, it is also a disguised explanation to Liu Yijiu why the big guy above did not directly put pressure on the Civil Aviation Administration and issue an airworthiness certificate to Yun Shi.

Liu Yijiu naturally understood this, and nodded vaguely at Qiu Yue, who had been staring at him, indicating that he understood and could understand. "That's true, so since we took over, Yun-10 has been constantly refining and improving, and at the same time conducting a lot of flight tests to verify our technical design. Even if there are no orders, we are not a loss, the reason why Yun 20 can complete the prototype for ground static pressure test so quickly, a lot of experience is due to the accumulation of a lot of experience in Yun Shi. ”

Inside the huge factory, there was a huge Yunxi that only had paint and some non-critical equipment not installed, standing quietly, and what these people talked about had no effect on it.

At the other end of the plant, a machine has completed the installation of the main structure such as the keel and girders, and there are many people busy next to the Yun 20 that have begun to take shape, and the assembly has not stopped because of the big guys.

It took a lot of time on this topic, and Qiu Yue changed the topic again, but it still didn't have much to do with Yun Twenty.

"At present, when the first flight of Yun 20 is successful, there will be two large aircraft in the large aircraft factory of the Ninth Academy, and I don't know what plans the large aircraft factory has in terms of production facilities and production capacity arrangements?" Qiu Yue's identity is a retired military bigwig, and the incoming deputy commander of the Blue Army, it is a little inappropriate to ask this question, although the question is about Yun 20, but even if the first flight is completed and the flight test is over, it will take several years.

Speaking of which, I still asked about the situation of Yun Shi.

Ma Fengshan and others didn't understand, but Liu Yijiu heard it from these words, and immediately said with a smile, "The design of Yunshi to the production process, all of which are the results of our own efforts in China, after we jointly researched the 70,000-ton large press with Erzhong, the strength problem of the main beam of our large aircraft has been effectively solved, and such a long test flight is also a test of the forging ability of our large press." After these key technical equipment have been effectively solved, we have a complete large aircraft production capacity...... Our large aircraft factory is located in Rongcheng, a lot of large parts and forging equipment long-distance transportation is not convenient, Erzhong, North Heavy Industry, Qin Fei, and some supporting units have begun to build production plants around this, so that the main key parts in Rongcheng and Deyang these places can be fully produced......"

Basically, after Yun 10 entered the Ninth Academy, Liu Yijiu continued to improve the supporting capacity of the large aircraft manufacturing industry.

What the Ninth Academy owns will be further developed and improved.

What the Ninth Academy does not have on its own, there are units such as North Heavy Industry, Erzhong, Shenfei, Qin Fei and even Hongdu Aircraft Factory to undertake the design and manufacture of some parts.

The world's most sophisticated scientific and technological equipment, and the large aircraft industry, which reflects a country's industrial strength and scientific and technological level, have begun to become perfect under the operation of the Y-10, a project that should have been eliminated.

"As for the engine, we have set up a research institute that mainly studies aviation power, and at the same time, an engine manufacturing company has been established next to it, and the manufacture of various precision machinery has also been established next to it...... At present, the design and production of large aircraft has been transformed from the original 708 to the 708 responsible for the design of the assembly and key technologies, and other domestic aviation units are responsible for the complete framework of some other systems and parts of the design......

Liu Yijiu has never reported the development of a large aircraft factory.

This is very different from their fighter jets, which are basically designed by the 611 Institute and produced by the 132 factory, and other domestic aviation units do not have much business in this regard.

A fighter jet is not the same as a transport plane.

Moreover, there are also some technical details that are involved in the secrecy.

"Your efforts are good. In the past, although there were many aviation units and more than a dozen aircraft factories in China, there was no perfect high-precision and cutting-edge aircraft R&D and production industry...... "Qiu Yue wrote down Liu Yijiu's report, he didn't understand this, but he could understand from Liu Yijiu's introduction that the Ninth Academy produces large aircraft, and any parts, even the most core aero engines and the most complex avionics systems of aircraft, are produced in China.

In other words, large aircraft do not need to import any parts from abroad!

Only high-end equipment that is completely localized can be said to have the strength of manufacturing.

"According to our plan, whether it is Yun 10 or Yun 20, in the first phase of capacity construction, the annual output will not be less than 12 aircraft, and various supporting factories around will be built according to this capacity or even higher capacity. After all, the production and manufacturing plants and processing capacity are relatively top in China, and it is completely possible to transfer the production capacity to other equipment...... "state-owned enterprises have such benefits."

Moreover, what China lacks most at present is high-end manufacturing capacity.

"With your development, Chengdu will become the city with the most high-end manufacturing capacity in the country! However, this place is located in the southwest, and the transportation is not very convenient......" Qiu Yue sighed a little.

In the 60s, when the country's third-line construction was carried out, most of the military enterprises were built in the southwest hinterland of the country, and the factories were all in the mountains, and there were some factories in Rongcheng, but they were some heavy industries that were not too important.

Heavy industry is mainly in the first line of Deyang Mianyang, while the high-end is in Daba Mountain.

Even in the 132 factory in Rongcheng, because it is only Shen Fei's backup company, there is no too advanced equipment, and it is nothing. China's industry is mainly concentrated in the northeast, which was left by the Japanese in those years, and a large part of the 156 heavy industry projects of the Soviet-aided republic were left there, and the country has been tilting its resources towards the northeast for decades.

Now, with the settlement of many industries in Rongcheng and the construction of more supporting industries in Rongcheng, Rongcheng, a non-industrial city, is rapidly transforming into a high-tech industrial city, just an aircraft manufacturing plant, there are two, one is the production and manufacture of J-10, J-11 132 factory, and the other is the Ninth Academy of large aircraft factory, which is not famous in China.

"There is nothing about transportation, after all, the important supporting facilities are in the surrounding area, mainly because the roads are really poor. However, in order to support our development, the provincial government and the municipal government of Rongcheng are currently vigorously building infrastructure facilities......" Liu Yijiu replied with a smile.
