The assembly of aircraft is not as simple as assembly of other equipment.

Liu Yijiu did not ask too much about the imitation of f14.

He is more concerned about the double-three projects designed by China itself, which is completely independently designed.

Once, Long Yaohua also asked Liu Yijiu that the three-fold sound and the 30,000-meter-highest fighter is actually not too practical, and it is more technically difficult. What's more important is that even the bodies of excellent pilots cannot maintain their bodies in such a flying state for too long.

The three-mach degree can exceed one thousand meters in one second. The overloaded body in this state is difficult for a long time to bear. Otherwise, an excellent pilot will be scrapped.

The original goal required by the senior military leaders, or the initial project was only double 26, that is, the flight altitude was 26 meters and the flight degree was 26 Mach. It was itself under the responsibility of Shenfei 61. In the end, the 611 was established and then transferred to the 611.

It is precisely because of the high performance indicators and not very practical, that the main targets of combat are the Soviet "Counterfire" and the American B1B sound bomber, which do not have much effect on other fighter jets and heavy fighter jets.

Liu Yijiu didn't say anything at that time, but he had the reason to have to make a twin-three-performance aircraft fly in extreme environments, which had very high requirements for pilots.

In this way, it is necessary to improve the pilot's response ability and at the same time improve the pilot's physical fitness. This requires more in-depth research on the human body, which leads to genetic engineering and some research on the potential of the human body.

This project in the Ninth Academy has always been carried out in secret, and even the top ones have few big men who know it. Liu Yijiu wants to conduct research on this aspect openly.

At the same time, such fighter jets have a very powerful role in intercepting strategic bombers from afar. To become heavy fighter jets, the bomb load capacity is higher and the combat effectiveness is stronger.

The Republic does not need to be equipped too many times, dozens or hundreds are enough.

Moreover, as long as the Double Three Project is successful, there will be more extended results

Liu Yijiu had no choice but to ignore it.

The frame in front of me is just assembled with the keels in key bearing parts. The others have not yet begun to be assembled.

There are also two turbofan eight-motors, avionics systems, etc., because the metal parts have not been assembled yet and have not been transported to the assembly workshop.

"Is the thrust of the Turbo Fan Eight sufficient?" Liu Yijiu asked with a frown. You know, the indicator of Double Three is not easy to achieve.

Feng Lun, the chief designer in charge of the double three project, nodded hurriedly and said to Liu Yijiu, "The turbofan eight that Mr. Qi and his team were responsible for designing, has used a three-level fan and a nine-level rectification, and the thrust-to-weight ratio has reached 138 thousand nm per unit, and the thrust-to-weight ratio has reached 8."

In terms of motivation technology, Liu Yijiu proposed a lot of technical indicators, and many times he also proposed some key things, and he even gave some guidance on many projects.

However, he has not followed the experiment recently, but he did not expect that the turbofan team of the 611 Institute had achieved such great results in this regard.

Hearing Feng Lun's words, Huang Qiaosong couldn't help but smile, "Old Huang, the technical indicators of this turbofan 8 were proposed by Director Liu. Many key designs were also modified by Director Liu."

Liu Yijiu just shook his head and did not explain anything about Huang Qiaosong's flattery.

Heart disease in the aviation industry in the Republic has always been criticized, limiting the development of the entire aviation industry.

However, under the current circumstances, the technology of such a motivation is not too stable. Even if it is barely achieved, it can only be used for a long time. The turbofan 10 of that year has been built for decades. I don’t know how many planes finally mature after falling.

"This requires a high level of demand for the manufacturing industry. We cannot just pursue performance indicators, safety, and stability one-sidedly. This is what we need. It is not that the motivation of one or two units has achieved results, which means that we have done a very successful job in this regard.

"Liu Yijiu understands what these people think.

There was no special incident during the development of the WT8, which made him a little incredible.

There have been countless special situations in the research of WT10, which allowed the experts of the Republic to find solutions to the problems and continuously improve them.

During the process of scientific and technological research, you are not afraid of problems, you are afraid of not having problems.

That's why Liu Yijiu asked this question.

He always felt that this motivation was too easy. Even if the overall turbine disk design was adopted, the experience in this area would not be enough to support it.

Whether it is the Soviet Union or the United States, they are exhibited from generation to generation. However, China is different. It has been developed across several generations, and without any problems, it will make people feel a little uneasy.

"There was no big problem with the experimental process of WT8, right?" Liu Yijiu asked everyone.

Qi Hai, who was in charge of the design, was not here, and no one else could answer.

"This is the first advanced fighter aircraft independently designed in our country. The process can be slower and safety must be ensured." Liu Yijiu emphasized the issue of safe production.

At the same time, quality accidents must be taken seriously.

"Director Liu, these motivations should not be problematic. I heard from Mr. Qi that during the design process, we not only referenced our turbofan 6, but also the R15 motivation of the MiG 25 and the F3P412 afterburner turbofan motor of the F14."

"Don't tell me what should be. Perhaps the uncertain issue is related to the future of our entire project, to the safety of pilots, and even national defense security." Liu Yijiu became angry when he heard this.

In technical research, such uncertain words must never appear.

Feng Lun was speechless when he said this.

This matter can only be asked by Liu Yijiu to ask the chief designer Qi Hai, who was motivated.

"Where is Qihai now?" Liu Yijiu asked about Qihai's location.

Motivation is the first technical problem that domestic fighter jets need to overcome.

Before this, you still have to listen to Qi Hai’s opinion first, otherwise even if you fly successfully, it will be a big problem to display it quickly.

Not to mention, fighter jets such as the J-20 and J-31 of the Republic made rapid progress after flying, but in the end, the degree of equipment was greatly affected by the motive issues. At that time, the domestic turbofan 18 and turbofan 2 had many problems and could only be equipped with the motivations imported from the Russians.

Although the Russians were desperate by the US imperialists, they did not have the motivation to supply China in this regard, so they should not count on technology or other things.

There are only interests between countries, but no eternal friendship.

When needed, you will naturally become an ally.

In the end, the Russians almost completely turned to the West, otherwise the pressure on the Republic would not be so great.

Electronic systems and radar systems can be a little worse, the motivation and other things are the heart of the entire fighter and the soul of the entire fighter.

"At Phoenix Mountain Airport, our turbofan 8 is undergoing an aerial platform test during this period." Liu Yijiu kept asking various questions, which made Huang Qiaosong and others unable to cope with it.

When Liu Yijiu heard this, he looked at the imitation f14 that had been assembled in the opposite corner, and his brows frowned even tighter.

However, he didn't say anything, but waited for the explanation from the group of people in front of him.

"Director Liu, this is the case. Due to the tight time and heavy tasks, the test of the Turbo Fan Eight was not completed. In order to ensure the smooth flight work, we did not use the Turbo Fan Eight, but instead dismantled the F14. "Under the pressure of Liu Yijiu, even Zhu Kedao had to tell the truth.

Whether the turbofan 8 can allow the imitation of F14 to fly, and during the test flight after the flight, the maneuverability of the imitation of fighter jets must be tested, etc. In order to ensure the smooth progress of the project, Liu Yijiu rarely has time to come here, and other people from the Management Committee of the Ninth Academy have never seen it.

After discussion, Huang Qiaosong and others took this approach in order to successfully fly.

After the explanation, everyone looked at Liu Yijiu carefully. The imaginary anger did not come. Liu Yijiu just sighed helplessly, and then said to everyone, "Eat a meal in the canteen here at noon, and then we go to the Phoenix Mountain Airport to see the situation."

Of course, the group had nothing to say, it was just noon now.

A casual lunch was settled in the cadre canteen of 132. The group took several cars and headed towards the Phoenix Mountain Airport, the largest military airport at the Rongcheng Air Force Base.

Phoenix Mountain Airport, the largest military airport in the entire southwest, was built in 1931 and expanded into a military airport in 1937. Then the Republic was established and has been expanding. It is an important airport for the Chengdu Military Region Air Force.

There are not many residents around such airports, and it is difficult for new fighter jets to leak information.

The same is true for Taiping Temple Airport, but there are a large number of residents around Taiping Temple Airport. Moreover, the Rongcheng Exhibition will expand in the future, and the exhibition in the south and west will expand soon. Liu Yijiu even thought not to build it there, and in the end, he put the Yunshi production line and research base at Taiping Temple Airport. Because it was a civilian aircraft, there was no need to worry about leaking secrets in appearance or something.

As for the final exhibition in Chengdu, such a huge aircraft factory can prevent a city from expanding and changing its direction.

The vigilance of the Fenghuangshan military airport is no less weak than that of Taiping Temple today, because it is the Rongcheng Air Force Base. Although it is only equipped with master aircraft such as J-7, H-6, and Strong Five, it is also the foundation of the entire Rongcheng Air Force.

After Qi Hai heard that Liu Yijiu had arrived here, he waited at the airport entrance early.

Accompanied by Geng Liguo, the commander of the Phoenix Mountain Base.
